By Robert Follansbee and H. J. Dean. SCOPE OF REPORT. This volume, which is one of a series of 12 reports presenting results of measurements of flow made on streams in the United States during the year 1913, includes all data concerning the Rio Grande and its tributaries collected prior to September 30 of that year. Systematic study of run-off in the Rio Grande basin was begun by the Federal Government near Embudo, N. Mex., soon after the passage of the act of October 2, 1888, which authorized the organiza- tion of the irrigation survey under the direction of the United States Geological Survey. A camp of instruction for hydrographers was estabhshed near Embudo, and at this camp and the gaging station near by, the methods of stream measurements now in general use were systematized. In the spring of 1889 additional stations were estab- lished on the Rio Grande near Del Norte, Colo., and El Paso, Tex. From this beginning the work of measuring the waters of the Rio Grande basin has been expanded not only by the Geological Survey acting alone but by the Survey in cooperation with the American section of the International Water Commission ^ and the State engineers of Colorado and New Mexico. At the end of September, 1913, records had been obtained at 93 gaging stations. The present report contains not only all data concerning stream flow in the Rio Grande basin collected by the Survey and cooperating parties but also records furnished by individuals connected with private interests. Most of the records here assembled have been taken from the publications of the Geological Survey, but original estimates have been revised where later data have indicated errors. The most notable necessity for revisions was in the older estimates of winter flow of the Rio Grande at Del Norte and Lobatos, the fig- ures given in the present report being considerably lower than those first published. Tables of daily discharge not heretofore pubhshed have been supplied from the original computations. 1 Prior to July 1, 1910, International Boundary Commission. 10 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. The drainage area is stated in connection with the run-off data for only a few of the stations, and no estimates of run-off per square mile have been made, for the maps for the greater part of the basin are so poor and the unit run-off for different areas varies between limits so wide that such estimates would be of little value. The results of studies of precipitation, evaporation, and sedimen- tation as factors in determining the value of reservoir sites for storage of flood waters, on which future development must largely depend, are also presented in this report. COOPERATION AND ASSISTANCE. The American section of the International Water Commission began the work of stream gaging in 1897, by taking over the station at El Paso, Tex., formerly maintained by the Geological Survey. In 1900 a number of stations on the lower Rio Grande and tributaries below El Paso were estabhshed by the American and Mexican sections of the Commission, and in 1901 the station on the Rio Grande at San Marcial was taken over from the Geological Survey. These stations have been maintained to the present time under the immediate direction of W. W. FoUett, United States consulting engineer, through whom the chairman of the commission has furnished the records and to whom special acknowledgments are due. A large part of the field data for the Pecos River basin was furnished by the United States Reclamation Service, by whom the stations were maintained. Since 1909 the State engineer of Colorado has cooperated in the maintenance of the stations in Colorado and for 1912 and 1913 he has furnished all field data. From 1907 to 1912 the work in New Mexico was carried on under the immediate supervision of the Territorial engineer. During the later part of 1912 a cooperative agreement was made with the State engineer and an office of the Geological Survey was established at Santa Fe in connection with the State engineer's office. Acknowledgments are due also to the State engineers of Colorado and New Mexico for cooperation in making a complete seepage inves- tigation of the Rio Grande from Del Norte, Colo., to El Paso, Tex., for use in this report. The United States Forest Service has prepared the data used in compiling the statements regarding forestation in the drainage basin. Mr. W. L. Rockwell, irrigation engineer, Department of Agriculture, furnished the records of evaporation at the United States Experiment farm near San Antonio, Texas. Mr. R. H. Forbes, director of the Agricultural Experiment Station at Tucson, Ariz., furnished the records of evaporation near Phoenix, Ariz. BIBLIOGEAPHY. 11 Acknowledgments are also due to a number of corporations and indi\dduals for furnishing records, as noted in connection with each station affected. The writers have assembled and reviewed the stream-flow data here presented and have made such changes in previously published figures as were necessary to reconcile apparent discrepancies. They have also reviewed and discussed the results of investigations of pre- cipitation, seepage, evaporation, and sedimentation. BIBLIOGRAPHY.

The volume of water flowing in a stream — the "run-off" or "dis- charge" — is expressed in various terms, each of which has become associated with a certain class of work. These terms may be divided into two groups — (1) those which represent a rate of flow, as second- feet, gallons per minute, miner's inches, and run-off in second-feet per square mile, and (2) those which represent the actual quantity of water, as run-off in depth in inches, and acre-feet. The units used in this series of reports are second-feet, second-feet per square mile, run-off in depth in inches, and acre-feet. They may be defined as follows : "Second-foot" is an abbreviation for cubic foot per second and is the unit for the rate of discharge of water flowing in a stream 1 foot wide, 1 foot deep, at a rate of 1 foot per second. It is generally used as a fundamental unit from which others are computed by the use of the factors given in the accompanying table of equivalents. "Second-feet per square mile" is the average number of cubic feet of water flowing per second from each square mile of area drained, on the assumption that the run-off is distributed uniformly both as regards time and area. "Run-off (depth in inches)" is the depth to which the drainage area would be covered if all the water flowing from it in a given period were conserved and uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is usually expressed in depth in inches. An "acre-foot" is equivalent to 43,560 cubic feet and is the quan- tity required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation.

The data presented in this report cover the years beginning October 1 and ending September 30, and not, as in previous reports, the calendar years. At the first of January in most parts of the country a large amount of precipitation for the preceding three months is stored, either as ground water in the form of snow, or in lakes. This stored water passes off in the streams during the spring break-up. At the end of September the only stored water available for run-off in the streams is possibly a small amount held in ground storage. Therefore, the run-off for a year, beginning with October 1, is practically all derived from precipitation occurring within that year. The use of this climatic year in studies of stream flow is applicable only to work in the Temperate Zone, as south of about the twenty- eighth parallel of latitude precipitation is greatest during the sum- mer months. The effect of the rainy season in Mexico is shown in the run-off data for all stations on the Rio Grande below El Paso, Tex. For each regular current-meter gaging station the following data, so far as available, are given: Description of the station, list of dis- charge measurements, table of daily gage heights, table of daily dis- charge, table of monthly and yearly discharge and run-off. For sta- tions located at weirs or dams the gage-height table is usually omitted In addition to statements regarding the location and installation of current-meter stations the descriptions give information in regard to 16 WATER EESOUECES OP EIO GEANDE BASIN, 1888-1913. any conditions that may affect the constancy of the relation of gage height to discharge, covering such points as ice, logging, shifting chan- nels, and backwater; also information regarding diversions which decrease the total flow at the measuring section. Statements are also made regarding the accuracy of the data. The table of daily gage heights records the daily fluctuations of the surface of the river as found from the mean of the gage readings taken each day, usually in the morning and in the evening. The gage height given in the table represents the elevation of the surface of the water above the zero of the gage. All gage heights affected by the presence of ice in the streams or by backwater from obstructions are pubhshed as recorded, with suitable footnotes. The rating table is not apphcable for such periods unless the proper corrections to the gage heights are known and applied. Attention is called to the fact that the zero of the gage is placed at an arbitrary datum and has no relation to zero flow or the bottom of the river. In general the zero is located somewhat below the lowest known flow, so that readings of negative values shall not occur. The discharge measurements and gage heights are the base data from which rating tables, daily discharge tables, and monthly dis- charge tables are computed. The rating tables gives, either directly or by interpolation, the dis- charge in second-feet corresponding to every stage of the river recorded during the period for which it is applicable. It is not published in this report, but can be determined from the tables of daily gage heights and daily discharge as follows : First plot the discharge measurements for the current and earlier years on cross-section paper, with gage heights in feet as ordinates and dicharge in second-feet as abscissas. Then tabulate a number of gage heights taken from the daily gage-height table for the com- plete range of stage given and the corresponding discharges for the days selected from the daily discharge table and plot the values on cross-section paper. The last points plotted wiU define the rating curve used and will He among the plotted discharge measurements. After drawing the rating curve a table can be developed by scaling off the discharge in second-feet for each tenth foot of gage height. These values should be so adjusted that the first difference shall always be increasing or constant except for known backwater periods. The table of daily discharge gives the discharge in second-feet corresponding to the observed gage heights as determined from the rating tables. In the table of monthly discharge, the colunm headed "Maximum" gives the mean flow, as determined from the rating table, for the day when the mean gage height was highest. As the gage height is the U. S.

ACCURACY AND RELIABILITY OF FIELD DATA. 17 mean for the clay, it does not indicate correctly the stage when the water surface was at crest height, and the corresponding discharge was consequently larger than given in the maximum column. Like- ^vise in the column of ''Minimum" the quantity given is the mean flow for the day when the mean gage height was lowest. The column headed ''Mean" is the average flow in cubic feet for each second dur- ing the month. On this the computations for the remaining columns, which are defined on page 12, are based. The field methods used in the collection of the data presented in this series of reports are described in the introductory sections of United States Geological Survey Water-Supply Papers 261 to 272, inclusive, "Surface water supply of the United States, 1909." Plate I shows typical gaging stations. Plate II shows current meters used in the work. ACCURACY OF FIELD DATA AND COMPUTED RESULTS. The accuracy of stream-flow data depends (1) on the permanence of channel and of the relation between discharge and stage, and (2) on the accuracy of observation of stage measurements of discharge, and interpretation of data. In order to give engineers and others information regarding the probable accuracy of the computed results, footnotes are added to the daily discharge tables, stating the probable accuracy of the rating cin-ves used, and an accuracy column is inserted in the monthly dis- charge table. For the rating curves "well defined" indicates, in gen- eral, that the rating is probably accurate within 5 per cent; "fairly well defined," within 10 per cent; "poorly defined" or "approxi- mate," within 15 to 25 per cent. These notes are very general and pre based on the plotting of the individual measurements with refer- ence to the mean rating curve. The accuracy column in the monthly discharge table does not apply to the maximum or minimum nor to any individual day, but to the montlily mean. It is based on the accuracy of the rating, the probable reliability of the observer, and knowledge of local conditions. In this column A indicates that the mean monthly flow is probably accurate within 5 per cent; B, within 10 per cent; C, within 15 per cent; D, within 25 per cent. Special conditions are covered by foot- notes. In general the base data collected each year by the Survey engineers are published not only to comply with the law but to aflord any engineer the means of examining and adjusting to his own needs the results of the computations. The table of montlily discharge is so arranged as to give only a general idea of the flow at the station and should not be used for other than preliminary estimates. The deter- 41823° — wsp 358—15—2 18 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. minations of daily discharge allow more detailed studies of the varia- tion in flow by which the period of deficiency may be determined. It should be borne in mind that the observations in each succeeding year may be expected to throw new light on data already collected and published. GENERAL FEATURES OF THE RIO GRANDE DRAINAGE BASIN. LOCATION AND BOUNDARIES. The area nominally belonging to the Rio Grande basin comprises the San Luis Valley and the region westward to the Continental Divide in Colorado, the greater part of New Mexico (except the western fifth of the State, and an area in the northeast corner approxi- mately 140 miles square), the western panhandle region in Texas, and a comparatively narrow strip along the lower river; in Mexico it comprises the greater part of the State of Chihuahua, large parts of Coahuila and Nuevo Leon, and small parts of Durango and Tamauhpas. (See PL III.) In Colorado the boundaries of the basin are clearly marked by the almost continuous ring of mountains separating it from the Arkansas basin on the east and the Colorado basin on the north and west. In New Mexico the boundaries are much less sharply defined, especially on the western border which reaches the high plateaus or mesas that characterize the greater part of the western section of the State and that commonly are either without surface drainage channels or form closed basins draining toward the center. In general, however, the western boundary may be said to coincide with the Cejita Blanca Range, Chacre Mesa, Zuni Mountains, and the west end of the Datil and Black ranges. From the northeast corner of Grant County the boundary line runs southwest to Bear Mountain, whence it takes a southerly direction to the Mexican Hne. The east- ern boundary in New Mexico is more clearly marked. As far south as Las Vegas it consists of the extension of the Sangre de Cristo Range; southeastward from Las Vegas it is well defined by the divides between the fines of natural drainage, until it reaches the high plateau region in Roosevelt County, where it again becomes indefinite, as this region of high plains is devoid of surface drainage fines. Beyond the region of high plateaus, which does not extend east of the one hundred and second meridian, the boundary is fairly well defined to the Gulf, lying paraUel to the Pecos at a distance of about 50 miles to the east, and below the mouth of the Pecos roughly paralleling the Rio Grande at an average distance of 30 miles. In Mexico the boundary of the nominal drainage area coincides with the mountain ranges in the western part of the State of Chi- House Doc. 959 ; 63d Cong., 2d Soss.

It turns eastward in the northern part of the State of Durango and takes a generally easterly course to the Gulf at the mouth of the Rio Grantle. As in the United States, however, the effective drainage area of the river is considerably reduced by the large nonproducmg areas. TOPOGRAPHY. The topographic features of the area drained by the Rio Grande range in variety from mountain peaks 14,000 feet and more in eleva- tion to the low plains bordering the Gulf. The most important area as regards water supply is the mountainous part of the Colorado section above San Luis Valley, where the Rio Grande and its tribu- taries flow through narrow valleys whose sides extend up to the crest of the Continental Divide. San Luis Valley is a high level plateau at an elevation ranging from 7,500 to 8,000 feet. The New Mexico section of the basin is a high plateau region traversed from north to south by more or less parallel mountain ranges that form long, narrow vaUeys, some of which are completely inclosed. In this area elevations range from 13,000 feet in the moun- tains near Santa Fe to less than 4,000 feet in the valleys of the Rio Grande and Pecos. Below El Paso, in the trans-Pecos region of Texas, there is a mountainous area that probably extends into the Mexican part of the basin and that, in Texas, attains altitudes of 7,000 to 8,000 feet. East and south of the trans-Pecos region the country gradually becomes smoother, passing from the liigh-plateau region to the Coastal Plain by crossing the fall hne below the mouth of the Pecos. The Coastal Plain is characteristically a region of comparatively low rehef, but its surface is broken by occasional undulations and hills of considerable height. CLOSED BASINS. As the Rio Grande as far south as El Paso and beyond traverses the high plateau or intermountain region, the drainage boundaries include many areas from which neither the river nor its tributaries receive any surface run-off. SAN LUIS VALLEY. The nonproducing area nearest the headwaters is found in San Luis Valley, in Colorado, north of the Rio Grande. The drainage from the entire northern portion of the valley flows into a group of lakes, of which the San Luis is the largest. As these lakes have no surface outlet, the water is lost by evaporation or possibly in part by seepage. "The old overflow drainage course to the Rio Grande still exists, but it has been so blocked and concealed by incipient 20 WATEE EESOTJRCES OF KIO GEANDE BASIN, 1888-1913. sand dunes as to be very difficult to trace, except in its general fea- tures."^ The drainage area included in this nonproductive basin is approximately 2,700 square miles. BASINS BETWEEN RIO GRANDE VALLEY AND PECOS BASIN. Beginning about 25 miles south of Santa Fe and extending as far south as El Paso, there is a wide strip of country stretching from within a few miles of the Rio Grande valley eastward to the Guadalupe, Sacramento, and Jicarilla mountains and the Sierra Blanca. This area is divided lengthwise by the Organ and San Andreas mountains, the Sierra Oscura, and the Chupadera Mesa into two distinct basins, each draining toward the center and having no outlet for surface drainage. The western division comprises the Jornada del Muerto ("journey of death," so called by the earliest travelers from its desert wastes), which is separated from the Rio Grande valley by the mountain ranges paralleling it. Within this area, which is an almost level plain, surface waters from the mountains drain toward the center but sink into the porous soil before reaching very far out on the plain. There are no cross-drainage channels. The eastern division includes at the north Estancia Valley a closed depression comprising an area of approximately 2,000 square miles, without perennial streams except tiny ones in the mountains that sink as soon as they reach the plain, and the Encino and Pinos Wells basins, lying east of Estancia Valley. Owing to the relatively elevated position of this area it is possible that some of the ground water may find its way into the lower adjacent regions.^ South of Estancia Valley is the Tularosa Basin, 150 miles in maximum length, 60 miles in maximum width, and containing approximately 6,000 square miles.^ Southeast of the Tularosa Basin, and separated fronT it by the Hueco Mountains, is a large nonproducing area which stretches to the Guadalupe Mountains on the east and nearly to the Rio Grande in El Paso, Culberson, Jeff Davis, and northern Presidio counties in Texas, and which is another practically closed basin, draining toward a central area where the water is lost by absorption and evaporation.* The nonproducing area between the Rio Grande and Pecos valleys above El Paso comprises approximately 13,000 square miles. 1 Siebenthal, C.

Across the Rio Grande from the Jornada is another closed basin, known as La Mesa, which extends from a point near Las Cruces southward into Mexico, sloping gently to the south. West of La Mesa is a closed basin several hundred square miles in area, which is drained by Mimbres River, an interior stream. Thus, it may be considered that the western boundary of the effective drainage area follows the Mimbres Range and then turns eastward, reaching nearly to the Rio Grande and paralling that stream within a few miles to the Mexican line. BASIN EAST OF PECOS RIVER IN NEW MEXICO. The Rio Grande basin in southeastern New Mexico comprises a part of the plateau area known as the High Plains and contributes no surface drainage to the river, for the rainfall is quickly evaporated or absorbed. The western edge of the High Plains area lies roughly parallel to the Pecos at a distance of 1 5 to 20 miles. The strip of area between the edge of the High Plains and the Pecos is almost devoid of drainage channels extending to the river, as the streams quickly lose themselves in the soil. Thus practically no surface run-off reaches the Pecos from the area lying to the east in Chaves and Eddy counties, N. Mex. Farther south, in Texas, the drainage lines are somewhat better developed, insuring the entrance into the Pecos of surface drainage from the eastern part of its basin. BASINS IN MEXICO. The region known as La Mesa in New Mexico extends southward into Mexico and merges with other nonproducing areas, cutting down the effective area from which surface run-off is secured to a compara- tively narrow strip along the western side of the Rio Grande from Juarez nearly to the mouth of the Rio Conchos. East of the com- paratively narrow area drained by Rio Conchos there is a large bolson or nonproducing area comprising many hundred square mUes in the southeastern part of Chihuahua, western part of Coahuda, and north- ern part of Durango. These two regions comprise approximately one-third of the nominal drainage area of the Rio Grande in Mexico, PRECIPITATION. PERIODS COVERED BY RECORDS. Relatively so few rainfall records of any considerable length are available for this section of the country that, in order to obtain a uniform basis for determining the distribution of rainfall throughout 22 WATEE EESOUKCES OF KIO GEANDE BASIN, 1888-1913. the Rio Grande Basin, it was necessary to use the comparatively short period of 10 years, from 1903 to 1912, inclusive, but even this period was too long to include more than three or four stations in the Colo- rado portion of the area, so it has not been possible to show graphically the distribution in that section. The part of the basin in New Mexico is fairly well covered with 36 10-year records and with sufficient records of greater length to enable comparison between the 10-year mean and the station mean for periods ranging from 30 to 54 years. The following table shows this comparison: Comparison between 10-year mean and station mean in New Mexico. Station. Length of record. Station mean. 10-year mean. Discrep- ancy.

The part of Texas drained by the Rio Grande is so sparcely settled that it has been impossible to obtain records covering the 10-year period from 1903 to 1912 at more than a dozen points within or bordering it. But as the distribution of rainfall is more uniform in Texas than in the upper part of the Rio Grande basin, these records are sufficient to show the distribution approximately.

DISTRIBUTION. The records of precipitation in the Colorado part of the Rio Grande basin are few and for the most part scattering, especially at the higher altitudes. The longest record is that at San Luis (elevation 7,794) in the eastern part of the San Luis Valley, and tliis is con- tinuous only since 1891. At Marshall Pass (elevation 10,856) there is an 8-year record; at Cumbres (elevation 10,015), a 5-year record; at Hermit (elevation 9,843), a 3-year record; and at Antelope Springs (elevation 8,902), a 3-year record. The remaining records are either at lower altitudes or are too meager to be of much value. The existing data show the mean annual precipitation to be heaviest on the Conejos Mountains on the western boundary. The annual precipitation at Platoro (elevation 10,015) is upward of 22 inches, and at Cumbres (elevation 10,800) observations in 1877 and 1878 showed a mean precipitation of 36 inches. In the upper part of the basin, although the altitudes are nearly as great, the precipitation is somewhat less, as shown by a mean of 16 inches for 2 years at Hermit (elevation 9,843) and a mean of 16 inches for 8 years at Marshall Pass (elevation 10,856). The gi-eater precipitation in the Conejos Mountains is probably due to the fact that to the west there are no large mountain masses to induce precipitation before reaching the Conejos Range, as in the case of the mountains bounding the headwater streams. The precipitation rapidly decreases with the altitude, falhng from the values just given to a mean ranging from 7 to 9 inches in the San Luis Valley, where tlie elevation ranges between 7,500 and 8,000 feet. The influence of the Sangre de Cristo Range, located on the eastern border of the area, in inducing rainfall, especially during the prevaiUng periods of easterly winds, is seen by the increased pre- cipitation as these mountains are approached. At Blanca (eleva- tion 7,865) the mean for 3 years is nearly 10 inches, and at San Luis (elevation 7,794) the mean for 22 years is 11.6 inches. Two years' record at La Veta Pass (approximate elevation 9,500) gives a mean precipitation of about 20 inches. To show grapliically the mean annual distribution of rainfall throughout the New Mexico and Texas portions of the basin, lines of equal rainfall for variations of 2 inches have been drawn on the map (PI. III). Altitude has such a marked influence on precipi- tation, especially in the upper parts of the basin, that it was neces- sary to take this into account so far as possible in showing the approxi- 24 WATER EESOUECES OF EIO GKANDE BASIN, 1888-1913. mate position of these lines. In the eastern part of New Mexico the relation between the two is fairly well defined and is shown on the map. No attempt was made to show local areas of high pre- cipitation due to detached mountain ranges as the data were too meager. For the higher altitude in the mountains northeast of Santa Fe, use was made of records as short as five and six years. The lines show the mean distribution of rainfall in New Mexico for the 10-year period 1903-1912, which, as explained on page 22, will probably not differ more than 2 inches for the mean variation for a much longer period. The chief characteristics of the distribution are the narrow belts of low precipitation following the Rio Grande and Pecos Valleys and the two areas of high precipitation, one in the mountainous region just north of Las Vegas, where means of 24 inches were obtained, and the other in the area of high altitude on the western edge of the Pecos basin in Otero, Chaves, and Lincoln Counties, where a mean of 23 inches was recorded. For the remain- der of the State the precipitation (with the exception of the isolated mountain ranges) ranges from 11 to 17 inches. In Texas the lines of precipitation are not so well defined as in New Mexico and are probably several inches lower than the mean for a long-time period. It is seen that the precipitation increases fairly uniformly from 9 inches near El Paso to 19 inches at the mouth of the Pecos. From that point to the eastern edge of Starr County it rapidly increases to 25 inches at the mouth. E,ELATTON BETWEEN PRECIPITATION AND RUN-OFF: Comparison between precipitation and run-off for the various parts of the United States has been made by Henry Gannett, of the United States Geological Survey, who found that where the annual precipi- tation is less than 20 inches no definite relation exists, as apparently the needs of vegetation require that much. With less than this amount of precipitation the run-off will depend almost entirely on the intensity of the rainfall rather than upon its total annual amount. Short violent storms will cause a comparatively large percentage of the precipitation to run off as surface water, whereas the same or even a larger total precipitation occurring as gentle showers may have practically no run-off, the water finding its way into under- ground channels, evaporating, or being absorbed by vegetation. As there are only a few points in the Rio Grande basin where the annual rainfall exceeds 20 inches, it is seen that no definite relation exists between precipitation and run-off. Any possible relation is still fur- ther complicated by diversion of the waters for irrigation and by the large nonproducing areas in the upper parts of the drainage area. GENERAL FEATURES OF RIO GRANDE BASIN. 25 FORE STATION.' By far the greater part of the forested areas in the Rio Grande basin in Colorado, and to a somewhat less extent in New Mexico, are included in the national forests. Data concerning forested areas in Texas and Mexico are lacking, but in Texas, at least, these areas are relatively unimportant. The headwater area in Colorado contains three national forests. Of these the Cochetopa lies in the basins of the Saguache and other tributaries of the San Luis, whose waters do not reach the Rio Grande at least as surface run-off, so that this forest may be disregarded in considering the effective area with respect to the Rio Grande. The San Isabel Forest may be disregarded for the same reason, as it embraces the northern part of the Sangre de Cristo range, from which no surface run-off reaches the Rio Grande. The Rio Grande Forest includes practically all the mountainous area in Colorado which con- tributes surface run-off to the Rio Grande, except a relatively small section in the southern part of the Sangre de Cristo range, from which the surface run-off per square mile is considerably less than from the other mountainous areas. The area of the Rio Grande Forest is 1,858 square miles. Owing to a number of causes, such as areas above timber line, open parks and grassy plains within the timber, and areas burned over by forest fires not more than 59 per cent, or 1,100 square miles, of the area within the forest can be considered timbered. The various types of timber with the relative area of each are given in the following table : Relative types of forest cover in Rio Grande Forest. Commercial : Per cent o f area.

Tolerant species — those which endure much shade — will, of course, cause much more shade and permit a more dense growth than an intolerant species. The Ehgelmann spruce is very tolerant of shade, • Prepared from data furnished by the U. S. Forest Service. 26 WATER EESOUECES OF RIO GRANDE BASIN, 1888-1913. and yellow pine is most intolerant. In a scale of 10 the following table will probably illustrate very closely the density of the different types of forest cover: Density of forest cover in Rio Grande Forest. Density (in a scale of 10). Engelmann spruce 7 Douglas fir 5 Western yellow pine 3 Pinon 3 Willows and aspen 8 The foregoing tables indicate that the species having the greatest density of growth — namely, Engelmann spruce, willows, and aspens — cover nearly 1,000 square miles, and the species having a very much lighter growth cover 110 square miles. About 758 square miles within the forest lack forest cover. In New Mexico the forested areas are found only in the mountain- ous sections, as on the plains the rainfall is too small to permit timber growth. In the area drained by the Rio Grande above El Paso the forested area amounts to approximately 10,000 square miles, of which 7,000 square miles are included in the national forests. It is impos- sible to give a close estimate of the amount of open land in the for- ests, but it is probably between 25 and 35 per cent. Assuming 30 per cent as land not timbered, the effective area within the 10,000 square miles would be reduced to 7,000 square miles. In these forests the denser species, such as spruce, willows, and aspens found in Col- orado, comprise a very much smaller area of forest, and therefore the forests in New Mexico are much more open than those in Col- orado. The many streams which sink into the ground before reach- ing the Rio Grande make it almost irdpossible to state with any degree of accuracy the effective forest area covering drainage basins whose waters actually reach the Rio Grande. POPULATION. The Rio Grande drains a section of the United States that is very sparsely settled. The following table, compiled from the reports of the Bureau of the Census, shows a population of the drainage by counties for 1910, 1900, and 1890, and the population per square mile: POPULATION.

In the headwater region, where mining is the chief industry, the population is about 1 per square mile and shows a decrease with the decline of tliat industry. The agricultural region, comprising Saguache, Rio Grande, Costilla, and Conejos counties, Colo., chiefly in the San Luis Valley, showed a substantial increase from 1900 to 1910 and, as might be expected, has a considerable denser population. The New Mexico part has shown a slow increase in population except in the southeastern quarter of the State, where the increase has been rapid, largely owing to the extension of irrigation, especially in Chaves and Eddy counties. The most thickly settled section is the north-central part of the State where irrigation has been carried on extensively for many years. Here the density is 5.3 per square mile for Taos, 7.5 for Santa Fe, 4.8 for San Mguel, and 19.4 for Bernalillo. The other sections where the density is from 1 to 3 per square mile are chiefly given over to stock raising, although in the valleys along the Rio Grande itself there are many thousand acres of irrigated land. The most sparsely settled section of the entire drainage area is the trans-Pecos region of Texas and the counties bordering it on the east. Here the average density of population is less than 1 .0 per square mile. Leaving the high plateau region and coming to the coastal plain the density increases from 2.6 per square mile in Kinney County to 4.1 in 28 WATER EESOURCES OP RIO GRANDE BASIN, 1888-1913. Maverick, 7.0 in Webb — falls off to 3.0 in Zapata, increases to 4.9 in Starr and 6.0 in Hidalgo Bounties. In general, the rate of increase has been greater in Texas than in either New Mexico or Colorado. THE RIVER.^ GENERAL FEATURES. The Rio Grande rises near the crest of the Continental Divide on the eastern slope of the San Juan Mountains in Colorado, at an elevation of approximately 12,500 feet above sea level, takes a general south- easterly course, and discharges into the Gulf of Mexico, a few miles east of Brownsville, Tex, From its source the river foUows an easterly course through a narrow canyon-like valley nearly to Del Norte, where the steep sides of the valley recede to inclose the large, level park-like region known as the San Luis Valley, which extends for a distance of 150 miles north to south with maximum width of 50 miles, and through which the river flows for the most part between low banks. From Del* Norte the general course of tlie Rio Grande is southeastward to Garland Junction, where it becomes southward. Four miles above the Colorado-New Mexico hne, at the lower end of San Luis Valley, the river enters a canyon locally known as the Rio Grande Canyon, which continues to the head of Espanola Valley near Embudo. This canyon increases in depth from 100 feet at the State Hne to 700 feet near the mouth of Rio Hondo and appears from above as a gash in an otherwise level mesa. The fall of the river through the canyon is about 30 feet per mile. For a large part of its remaining course the stream passes through a succession of valleys or erosion basins which are separated by rock canyons and are limited in form and size by the character of the material in which they were excavated. From the lower end of the Rio Grande Canyon the river flows through Espanola Valley (which is 3 to 4 miles wide and extends to a point near San Ildefonso) and enters White Rock Canyon, a narrow gorge, about 20 miles long and in places 500 feet deep, which owes its existence to sheets of hard igneous rock that protect the under- lying sands and gravels. The fall in this canyon is about 10 feet per mile. At a point almost directly west of Santa Fe, the river enters Santo Domingo Valley, through which it flows to the upper end of San FeUpe Canyon, 7 miles south of the Indian pueblo of Santo Domingo. This vaUey is 1 to 3 miles wi.de and contains about 13,000 acres of bottom land that has been irrigated for many years. The greater part of this land Ues only a few feet above the bed of the river and is subject to frequent overflow. 1 The description of the part of the drainage basin in New Mexico is taken largely from Lee, W. T., Water resources of the Rio Grande Valley in New Mexico: U.S. Geological Survey Water-Supply Paper 188, 1907. THE EIVER. 29 Passing: throii2:h San Felipe Canyon, which is a short gor^e, the river entei-s Albuquerque Valley, through which it flows for a distance of about 35 miles until it reaches Isleta Narrows. Albuquerque Valley ranges in width from 1 to 5 miles and comprises approxi- mately 70,000 acres of bottom land. It is bounded on both sides by steep bluffs of sand and gravel. The narrowing at Isleta Narrows is caused by the presence of the hard igneous rock of an extinct volcanic cone west of Isleta. Below the narrows the river flows for 45 miles through Belen Valley, which extends to San Acacia and contains approximately 65,000 acres of bottom land. From Belen Valley the river passes through San Acacia Gorge — a short, narrow gorge, 250 feet deep, cut through an arm of the lava sheet which crosses the river course — and entei-s Socorro Valley, which extends southward to San Marcial, a distance of 40 miles and comprises about 60,000 acres of bottom land. Beginning a short distance below San Marcial is a narrow vaUey, about 40 miles long, which is cut in detritus and which differs from the othei-s in being very narrow and having no bottom lands. This valley is the site of the Engle reservoir under construction by the United States Reclamation Service. A few miles north of Elephant Butte the river enters a narrow rock canyon which extends to the end of the Caballos Mountains and in which, opposite Elephant Butte, is the Engle dam site. Below Elephant Butte Canyon the Rio Grande flows through Las Palomas Valley to Rincon, a distance of 50 miles. The bottom lands in this vaUey include approximately 26,000 acres. From Las Palomas Valley the river enters Selden Canyon, which is 18 miles long but is not so uniformly narrow as the previous canyons, containing about 8,000 acres of bottom land. Emerging from Selden Canyon at old Fort Selden, the river enters Mesilla Valley, the largest of the erosion basins of the Rio Grande, extending southward 50 miles to The Pass. The valley has a maxi- mum width of 8 miles and contains approximately 150,000 acres of bottom land. It is cut in unconsoUdated sand and gravel, its floor being 300 feet lower than the mesa level. Below Mesilla Valley, just above El Paso, the river flows through a narrow gorge about 90 feet deep, cut in a low ledge of hard rock. From El Paso to its mouth the river forms the boundary between the United States and Mexico. For a distance of 100 miles below El Paso it flows in a broad lowland known as El Paso Valley, 250 feet below the general upland level. This plain becomes gradually nar- rower, until it terminates at a point 100 miles southeast of El Paso and the river cuts through a narrow gorge, 5 miles long, formed by the southeastern extension of the Quitman Mountains. 30 WATER EESOURCES OF EIO GEANDE BASIN, 1888-1913. Below the canyon is another broad valley, 16 miles long, which terminates a few miles above the mouth of Glenn Creek. For the next 60 miles the river flows through a mountainous region where the valley is narrow and in many places gorgelike. Near Ruidoso the mountains recede, leaving a broad valley with comparatively gentle side slopes. This characteristic of the topography continues for the next 60 miles (measured in a straight hne) until at a point about 20 miles below Presidio the river again enters a canyon. Thence to the fall line, near Del Rio, the river flows through a succession of canyons and narrow valleys, with an occasional area in which the mountains are sufficiently far apart to include valleys of considerable area. From Del Rio to the mouth the river flows through the coastal plain region, which is characterized by comparatively low topographic reUef, and a few miles east of Brownsville, Tex., it discharges into the Gulf of Mexico. TRIBUTARIES. Above San Luis Valley the tributaries of the Rio Grande are perennial mountain streams, the most important (named in descend- ing order) being Pole, Lost Trail, Glear, Crooked, Calma, Willow, and Hot Spring creeks and the South Fork. Little water is diverted from the Rio Grande and its tributaries before it enters the valley, so the flow at that point represents the natural run-off from approximately 1,200 square miles of mountain area ranging from 8,000 to 14,000 feet in altitude. Through San Luis Valley the Rio Grande received no perennial tributaries from the north and east as the run-off from the Saguache and tributaries which drain the northern part of the valley is lost by seepage and evaporation before reaching the river. The Trinchera and the Culebra, which enter from the east, together with the Costilla, which enters from the west just south of the Colorado-New Mexico line, are important tributaries during the spring run-off and after heavy rains but are dry during portions of the year. From the west are received the waters of Wolf, Los Pinos, and San Francisco creeks in the vicinity of Del Norte, and Rio Alamosa, La Jara Creek and Conejos River, none of which, although perennial streams, represents the natural run-off from its drainage area on account of the many irrigation diversions and the possible seepage losses in crossing the valley. Between the State line and the mouth of Chama River the only perennial tributaries of importance are Rio Colorado, Rio Hondo, Embudo Creek, and Rio Taos. Chama River, which enters the Rio Grande at Chamita, is one of the most important tributaries of the upper river. From Chamita to Albuquerque the only noteworthy tributaries are Santa Cruz, Santa Clara, San Ildefonso, and Jemez RIO GRANDE, 31 rivers. As the Santa Cruz and San Iklefonso have their source in the Sangre de Cristo Mountains they are probably perennial streams, although confirmatory records are lacldng. The Jemez, which enters a short distance above Bernalillo, carries but little water to the Rio Grande except during the spring floods. The eft'ect that underground sources have upon the flow of the river is shown by the various seepage measurements made. (See p. 679.) From Albuquerque to El Paso the Rio Grande has no important perennial tributaries. The largest flood stream is Rio Puerco, which drains a large area but is dry at its mouth the greater part of the year. There are many smaller flood-water tributaries, such as the Alamosa, CuchiUo, Negra, Palomaso, Seco, Las Animas, and Percha, all entering from the west. The drainage from the east with the exception of a very small part, is cut off by the interior basin known as the Jornada del Muerto (see p. 20). Thi-oughout New Mexico, and, to a less extent, the trans-Pecos region of Texas, the tributary run- off comes chiefly in the form of flood flow following torrential rains. Note- worthy perennial tributaries are also lacldng in the Texas part of the drainage basin between El Paso and the Pecos, which enters the Rio Grande about 40 miles northwest of Del Rio. Devils River, which is also a perennial stream enters a short distance above Del Rio. Below Devils River the basin is so narrow that tributaries are unimportant. Little information is available regarding the Mexican part of the drainage area beyond the fact that the only noteworthy tributaries are Rio Conchos, which enters nearly opposite Presidio, and Rio Salado and Rio San Juan, which enter below Laredo. GAGING STATION RECORDS. RIO GRANDE AT THIRTYMILE BRIDGE, NEAR CREEDE, COLO. Location. — In sec. 13, T. 40 N., R. 4 W., in the Rio. Grande National Forest, about 30 miles southwest of Creede, a short distance above mouth of Squaw Creek. Records available.— June 18, 1909, to September 30, 1913. Drainage area. — 163 square miles (measured from topographic sheets). Gage. — Chain gage, 200 feet upstream from Thirtymile Bridge, washed out October 5, 1911. The flood of this date changed the mouth of Squaw Creek, making it enter above the gaging station. For that reason when the records were resumed April 8, 1912, a vertical staff gage was established a quarter of a mile above the old site and above the new mouth of Squaw Creek. The relation between the gages was not determined. Channel. — Apparently permanent at new site. Discharge measurements. — Made from car and cable, except during low stages, when they are made by wading. Winter flow. — Ice causes backwater during the winter months and records are discontinued. Diversions. — So far as known no water is diverted above the station, and therefore the records represent the natural run-off. 32 WATER RESOURCES OF RIO GRANDE BASUsT, 1888-1913. Storage. — A short distance above the station the San Luis Valley irrigation district is constructing a reservoir of 43,000 acre-feet capacity which, when completed, will materially modify the flow of the river. During the low water of 1912 the operation of the reservoir gates controlled the flow somewhat, and during 1913 the flow was almost wholly controlled. Accuracy. — Owing to the high altitude at this point it is possible that at certain seasons of the year the alternate melting and freezing may cause considerable diurnal fluctuation. For this reason the mean daily gage height taken from morning and evening readings may not represent accurately the true mean for the day. With this exception, conditions are favorable for accurate results and the records as a whole are considered good.^ Cooperation. — Station maintained in cooperation with Mr. J. C. Ulrich, of the San Luis Valley irrigation district, by whom the field data were furnished. Discharge measurements of Rio Grande at Thirtymile Bridge^ near Creede, Colo., in 1909- 1913. Date.

RIO GRANDE NEAR CREEDE, COLO. Location. — In the Rio Grande National Forest, at highway bridge about sec. 8, T. 41 N., R. 1 E., one-quarter mile from Wason siding, and 3 miles east of Creede. Nearest tributary, Willow or Goblin Creek, enters a short distance upstream. Records available.— April 24, 1907, to September 30, 1913. Drainage area. — 705 square miles. Gage. — An automatic recording gage, referred to the same datum as the chain gage used previously. Channel. — Practically permanent. Discharge measurements. — Made from bridge. Winter flow. — River frozen over during winter months; ice causes backwater at gage and discharge measurements are made to determine the winter flow. Diversions. — There are no court decrees for diversions from the Rio Grande above this station, but for diversions of 39 second-feet from tributaries. There are no reservoirs on the river between this station and the one at Thirtymile Bridge, but a large one is being built on Clear Creek, which enters between. Accuracy. — Records good. S8 WATER EESOUECES OF EIO GRANDE BASIN, 1888-1913. Cooperation. — Since 1911 this station has been maintained in cooperation with the United States Forest Service and the State engineer. The records for 1912 and 1913 were furnished complete by the State engineer. Discharge measurements of Rio Grande near Creede, Colo., in 1907-1913. Date. 1907.

Records available.— April 16, 1908, to September 30, 1913. From July 1, 1889, to November 30, 1906, a station was maintained about 4 miles below the present station and just above Los Pinos Creek. The flow at the two points is not directly comparable, as a number of small streams contribute water during certain seasons, and a small amount of water is diverted for irrigation. Drainage area. — Approximately 1,400 square miles. Gage. — Automatic recording gage, the property of the State engineer, installed November 8, 1910. This gage is referred to the same datum as was the chain gage installed May 16, 1908. The gage datum used at the original station remained unchanged. Channel. — Shifting from year to year. Discharge measurements. — Made from bridge at present station and from car and cable at original site. EIO GRANDE. 47 Winter flow. — River is frozen over during the winter monttie, and measurements are made to determine the approximate discharge. Diversions. — There are court decrees for diversions of 101 second-feet from the Rio Grande between the Creedeand Del Norte stations, and for diversions of 162 second- feet from intervening tributaries. Cooperation. — Station maintained since 1910 in cooperation with the State engineei, who furnished complete the records for 1912 and 1913.

The ice period for each winter is somewhat uncertain, but its begin- ning has been determined from the rise due apparently to backwater from ice which occurred either in November or December.

This evidence is corroborated by the measurements made during the winters of 190S-1909, 1909-1910, 1910-1911, 1911-1912. Measurements made in 1913 apparently contradict the above evidence, probably because both ice measurements in 1913 were made after periods of severe cold weather, when the flow was temporarily reduced below the average amount. Subsequent to 1910 the winter estimates have been based almost directly on the discharge measure- ments. From 1899 to 1903 the estimates were based chiefly on the flow at Eihbudo which was practically unaffected by ice, an allowance ranging from 150 to 250 second-feet being made for the increased flow be- tween the two points. From 1904 to 1909 the winter estimates were based chiefly on the low-water flow in the fall before the river froze over. Comparison being made with the same conditions at the Del Norte station. Prior to 1910 the winter estimates are uncertain owing to insufficient data, and can only be considered approximate. Those for 1904 to 1909 are only roughly approximate and have been given merely to complete the yearly record. Records for 1911-13 furnished by the State engineer. 41823° — wsp 358 — lo 7 98 WATER EESOUECES OP EIO GKAiSTDE BASIN, 1888-1913. RIO GRANDE AT EMBUDO, N. MEX. Location. — At Santa Barbara Tie & Pole Co.'s bridge, a few hundred feet below the Denver & Rio Grande Railroad eating house at Embudo, at the mouth of the box canyon at the entrance to Espanola Valley, near sec. 27, T. 23 N., R. 9 E. The nearest tributary, Santa Barbara Creek, joins the Rio Grande about 3 miles above the station. Records available.— December 21, 1888, to December 31, 1903; September 8, 1912, to September 30, 1913. Drainage area. — Approximately 10,100 square miles. Gage. — Automatic recording. From January 1 to February 28, 1889, a gage was maintained 1 mile above Embudo, but moved to a point 1,500 feet above the site of the present gage March 1, 1889, and used until December 3,1903. The datum of this gage remained unchanged from March 1, 1889, to December 31, 1903. On September 8, 1912, an automatic gage was installed which was referred to a new datum. Channel. — Subject to a change during flood stages, but fairly permanent at low stages. Discharge measurements. — By wading at low stages and from a cable during flood and medium stages. Winter flow. — Relation between gage height and discharge during the winter months little, if any, affected by ice. Diversions. — Between Lobatos station and Embudo the Rio Grande flows through a canyon, so that there is practically no diversions from the river. Accuracy. — Estimates of daily discharge for 1912 can be considered only fair; those for 1913 are good. Cooperation. — During 1912 and 1913 station maintained in cooperation with the State engineer; prior to that date by the United States Geological Survey alone.

Estimates for 1900 and 1901 have been revised. Those for 1900 are based on a rating curve well defined below 3,500 second-feet; those for 1901 are based on two well- defined rating curves, one used from Jan. 1 to July 27, and the other used for the remainder of the year. Daily discharges for 1902 and 1903 were ftirnished by the International Water Commission and are based almost directly on the discharge measurements. Daily discharge for 1912 determined from two fairly well- defined rating curves, and that for 1913 from a curve well defined except for the period Mar. 17 to Apr. 1, when the indirect method for shifting channels was used. The daily values for 1913 represent the mean of 24 hourly discharges and not the discharge obtained from the daily mean gage height. Dec. 21, 1912, to Jan. 17, 1913, estimated on account of ice.

(See footnote to daily gage heights.) 120 WATER EESOURCES OF EIO GEANDE BASIN, 1888-1913. RIO GRANDE NEAR BUOKMAN/ N. MEX. Location. — At the Denver & Rio Grande Railroad bridge, at the head of White Rock Canyon, 4 miles above Buckman, 2 miles below the Indian village of San Ilde- fonso, about sec. 18, T. 19 N., R. 8 E. The nearest stream is Tesuque Creek, which enters near San Ildefonso. There is an arroyo just above the station. Records available.— February 1, 1895, to December 31, 1905; June 23, 1909, to September 30, 1913. Drainage area. — Not measured. Gage. — Automatic recording gage installed in June, 1910. The original gage was located on the left bank, 180 feet above the bridge. On March 30, 1904, avertical staff gage was established at the bridge at a datum 2.02 feet higher than the original datum. The datum of the present gage is the same as that of the gage established in 1904. Channel. — Shifting, as a result of scour and fill of sand on lava bowlders. Discharge measurements. — Made from car and cable originally located near the gage, but moved 3 miles below the gage in 1910. No diversions or important tributaries between the two points. Winter flow. — Only slightly affected by ice. Diversions. — Between Embudo and Buckman the bottom lands in Espanola Valley are u'rigated extensively. In 1896 W. W. Follett, of the International Water Boundary Commission, reported that ditches having a capacity of 406 second-feet diverted water from the Rio Grande between the two points. Accuracy. — Prior to the flood in October, 1911, conditions were favorable for accurate results, but the flood caused considerable change which was not fully covered by field work. Thus the estimates from October, 1911, to May 1, 1912, can not be considered better than fair. The records thereafter can be considered good.

MEX. Location. — At the Atchison, Topeka & Santa Fe Railway bridge, 1 mile south of San Marcial, in sec. 19, T. 7 S., R. 1 W. No important tributaries enter in the imme- diate vicinity of the station. Records available. — January 29, 1895, to September 30, 1913. Gage. — Inclined staff gage established January 29, 1895, and carried away by flood in 1896. A wire gage was established in its place at the same datum. This was soon abandoned and the gage heights have since been measured with a graduated rod from the bridge deck to the water surface. The gage datum of the inclined staff and wire gages is still used . Channel. — Sandy and very shifting; current broken by a number of bridge piers. Discharge measurements. — Made from the downstream side of the bridge. Diversions. — Between Buckman and San Marcial the bottom lands along the river are extensively irrigated. In 1896 W. W. Follett, of the International Boundary Commission, estimated that ditches having a capacity of 1,779 second-feet diverted water from the Rio Grande between these points. Cooperation. — Station maintained since 1901 by the American section of the Inter- national Water Commission, by whom the records are furnished. 142 WATER EESOUECES OF RIO GRANDE BASIN, 1888-1913.

Location. — At the Haciendita, 9 miles above Presidio, and 8 miles above the mouth of Rio Conchos, one of the principal tributaries of the Rio Grande. On September 26, 1905, the station was moved 8 miles farther upstream and maintained at that point until July 6, 1909, when it was removed to the original site. As no tribu- taries enter between the two points the flow is the same at both sites. Records available.— May 22, 1900, to September 30, 1913. Drainage area. — Not measured. 204 WATER RESOURCES OF RIO GRANDE BASIK, 1888-1913. Gage. — Inclined staff. Relation between the gage readings at the two sites or between the two gages used at the present site not determined. Channel. — Shifting greatly.. Discharge measurements. — Made from car and cable. Diversions. — No data. Accuracy. — Owing to the shifting channel, discharge measurements are made very frequently and the estimates of daily discharge based almost directly on these. Cooperation. — Station maintained by the United States section of the International Water Commission, by whom the records are furnished.

Location. — At the east end of the canyon section, half a mile south of Langtry, and a few miles above the mouth of the Pecos. Records available. — May 1, 1900, to September 30, 1913. Drainage area. — Not measured. Gage. — Vertical staff. Channel. — Very shifting and subject to overflow at stage of 29.5 feet. The overflow extends 110 feet back of the main bank. Discharge measurements. — Made from car and cable. Floods. — Below the Rio Conchos the Rio Grande is subject to severe floods from that source. Since the records have been maintained the highest flood occurred Sep- tember 13, 1904, reaching a stage of 34.25 feet and a discharge of 132,000 second - feet. This is somewhat less than the maximum stage of 149,200 at the station below Presido, showing the slight retarding effect of the channel upon flood flow. Diversions. — No data. Accuracy. — Owing to the shifting of the channel very frequent discharge measure- ments are made and the estimates of daily discharge based almost directly on these. Cooperation. — Station maintained by the United States section of the International Water Commission, by whom the records are furnished.

RIO GRANDE NEAR BROWNSVILLE, TEX. Location. — One mile above Brownsville, opposite Matamoras, Mexico. Records available.— April 29, 1900, to September 30, 1913. Gage. — Vertical staff. Chaimel. — Shifting. Discharge measurements. — Made from car and cable. Natural storage. — Between Roma and Brownsville there are many lagoons (old river channels) which take river water during moderate floods, and a large area is overflowed deeply in large floods. Much of this water returns slowly to the river as the floods subside, thus making the flow more uniform at Brownsville than at Roma. Large quantities also leave the river entirely, reaching the Gulf of Mexico by other channels. Accuracy. — Although frequent discharge measurements have been obtained, no estimates of daily discharge have been made by the commission. Cooperation. — ^This station is maintained by the Mexican section of the International Water Commission, by whom the base data are furnished.

SAN LUIS CREEK BASIN. GENERAL FEATURES. San Luis Creek rises in Poncha Pass at an elevation of about 9,000 feet and flows southward across the San Luis Valley to the San Luis lakes. Although the San Luis itself rises at a comparatively low altitude, its numerous tributaries take their rise in the high moun- tains of the Sangre de Cristo and Saguache ranges at altitudes of 12,000 feet and over. From the Sangre de Cristo the lai^er tribu- taries are Cotton, Wild Cherry, Rito Alto, San Isabel, Crestone, WiUow, Spanish, Cottonwood, Deadman, and Arena creeks. Many of the tributaries from the eastern range reach the San Luis. Of those from the western ranges — Saguache and La Garita — only Kerber and Saguache creeks reach it, the other streams sinking into the porous soil of the vaUey soon after leaving the mountains. The San Luis drains the northern part of the San Luis Valley, which may be considered an interior basin as no surface water escapes from it. The drainage of the northern part of the valley is toward the San Luis lakes, where the water is lost by seepage and evaporation. The old overflow channel to the Rio Grande still exists, but it has been so blocked by incipient sand dunes as to be almost obliterated in many places. The rock formations of the western boundary of the drainage area dip toward and extend beneath the valley, as in the Conejos Range described in connection with the Alamosa and Conejos drainage basins. Little is known of the geology of the Sangre de Cristo Range, which forms the eastern boundary of the drainage area, but the axis of the range is in general made up of intrusive granite flanked on both sides by conglomerate. Between the eastern boundary and the western, where the higher peaks reach elevations of 14,000 feet above sea level, is the high-level plateau comprising the San Luis Valley. The slope of the eastern range of mountains is much more abrupt than that of the western, so that the alluvial fans formed where the streams debouch onto the valley floor are much steeper on that side. From the axis of the valley, which is occupied by the channel of San Luis Creek, the country rises to the foothills, steeply eastward, very gently westward, at first not more than 3 to 6 feet to the mile, but gradually increasing until near the foothills the rise is quite perceptible to the eye. The floor, of the valley, ranging in elevation from 7,500 to 8,000 feet above sea level, is covered with a series of blue clays and inter- stratified sands which yield artesian water. Flowing wells are most numerous in the area drained by Saguache Creek. SAN LUIS CREEK BASIN. 347 Precipitation in the vSaii Luis Valley probably ranges from 16 to 20 inches or more in the mountains to 13 inches at the upper end and 8 or 9 inches at the lower, but, owing to the porous character of the soil and to the lack of drainage channels, only a small part of the rainfall reaches the San Luis, the remainder being lost by seepage, as shown by the fairly abundant supply of underground water, and by evaporation. A general description of precipitation in the valley is presented on page 23. Tlie watei-s of the San Luis and its feeders are used for irrigation and are greatly overappropriated, there being adjudicated decrees for diversions of 1,900 second-feet, of which approximately 750 second-feet are for diversion from the Saguache and its tributaries. So far as known the only reservoir that has been built in the basin is the State reservoir near Saguache. It has a capacity of 954 acre- feet, but as it has no adjudicated rights, and as the flood flow of the Saguache is entirely appropriated, it has not been used to any extent. GAGING STATION RECORDS.

RIO ALAMOSA BASIN. GENERAL FEATURES. Rio Alamosa, one of the important tributaries of the Rio Grande in its upper course, rises in the Conejos Mountains at the western edge of the San Luis Valley, near the crest of the Continental Divide. Its general course is eastward across San Luis Valley, and it joins the Rio Grande about 6 miles below Alamosa. It has a few short tributaries in the mountainous part of its course but none after reaching the valley. The upper fourth of the Alamosa basin lies in the Conejos Range, where the elevations reach 12,000 feet and more above sea level and the river and its tributaries flow through narrow valleys. The detri- tus brought down from this mountainous section has been deposited 356 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. at its entrance to the valley in the form of an alluvial fan of sand or gravel, similar to those built up by practically all of the mountain streams entering the valley. As the gradients of the streams issu- ing from the Conejos Kange are not so steep as those of streams flowing from the Sangre de Cristo Range, the resulting fans are not so prominent. Across the valley the river flows in a shallow channel only a few feet deep, and owing to the porous character of the allu- vial fan it probably loses water by seepage after it leaves the moun- tains. The following description of the geology of the Alamosa basin is taken from ' 'Geology and water resources of the San Luis Valley," by C. E. Siebenthal: ' The western moimtains, the Saguache and Conejos ranges are made up on their eastern flanks, adjacent to the San Luis Valley, of alternations of gi-avel beds, andesitic flows, and rhyolitic tuffs cut through in places by dikes and volcanic necks of centers of effusion. These flows incline toward the valley with dips varying from 6° to 15°, and extend under it, being penetrated in some of the wells at the south end of the valley. [In the valley proper these flows are covered with a series of blue clays, having interstratified sand beds.] Alamosa Creek leaves the foothills about d miles west of Capulin, through a defile in the lava rim. The south side of the defile rises into a bluff a hundred feet high which is capped with pyroxenite-andesite 40 feet in maximum thickness. * * * The lower part is massive and lies upon a water-sorted conglomerate, at the contact with which the lava is much broken. Bowlders from the conglomerate seem to be drawn up into the lava, and it is penetrated by crevices and "chimneys" of loose- textured rock, apparently the result of steam escaping when the flow covered the con- glomerate. The conglomerate has a burnt, reddish color, and the sandy matrix is more or less consolidated and indurated. These gravel beds rise upstream and 300 yards west come to the top of the bluff where they are interbedded with and under- lain by brecciated pumice or rhyoUtic tuffs. * * * [It is believed that a period of local glaciation antedated the last lava flow in this vicinity.] The Alamosa glacier manifestly occupied the U-shaped valley down nearly to the "box-canyon," spread- ing across the flat west of Chiquita Peak into the valley of Cat Creek. Below the "box-canyon" there are two terraces both developed on the south side of the valley. The lower one, apparently alluvial, is 60 feet high and 100 to 150 yards wide. The upper one, 30 feet higher, is covered with bowlders, in part glacial, and has an irreg- ular surface. * * * A mile farther down the creek a third terrace sets in 35 feet high above the valley bottom. Precipitation on the Conejos Mountains, in which the Alamosa rises, is heavier than in any other part of the region drained by the Rio Grande. At Platoro (elevation 9,800) the mean precipitation is upward of 23 inches, and at Summit (elevation 10,800) the mean for 2 years shows approximately 36 inches. On the mountain summits it is probable that the precipitation is even greater, as it increases with the altitude. A large part of this occurs in the form of snow, which is the source of the high-water in the streams in May and 1 U. S. Geol. Survey Water-Supply Paper 240, pp. 29, 30, 33, 1910. RIO Al.AMOSA BASIN. 'rW Juno. Tlie precipitation in the valley part of tlie drainafije basin is ap])roximately 8 inclies. The only artificial storage on the Alamosa is that afforded by the Terrace reservoir, near Terrace post office in T. 36 N., R. 6 E. Its capacity is approximately 17,000 acre-foot at the present time, and it is designed to store the flood waters for use in irrigating lands in the Terrace Irrigation District. The waters of the Alamosa are used extensively for irrigation in the San Luis A'alley, there being court decrees for appropriation of 1,700 second-feet by direct diversion from the Alamosa, GAGING STATION RECORDS. RIO ALAMOSA NEAR MONTE VISTA, COLO. Location. — In the Rio Grande National Forest, in eec. 2, T. 36 N., R. 5 E., 28 miles southwest of Monte Vista, a short distance below the mouth of French Creek, and about 6 miles above the Terrace reservoir dam. Records available. — September 29, 1911, to June 4, 1912. Drainage area. — 91 square miles ^ (measured from Forest Atlas). Gage. — Vertical staff. Channel. — Data too few to be conclusive. Discharge measurements. — Made from bridge 1 mile above gage during high w^ater and by wading at ordinary stages. Winter flow. — No information. Diversions. — The station is above all diversions except a ditch and flume used for hydraulic power at Terrace reservoir, which takes water half a mile above. There are court decrees for diversions of 1,700 second-feet from Alamosa River below the station. Accuracy. — ConditiouB are favorable for fairly accurate results and the estimates are considered fair. Cooperation. — Station maintained in cooperation with the United States Forest Service.

Location. — About 1,000 feet below the Terrace reservoir dam, in sec. 14, T. 36 N., R. 6 E., about 24 miles northwest of La Jara. No important tributary within several miles. Records available.— April 18, 1909, to October 22, 1912. Drainage area. — 120 square miles (State engineer's report). Gage. — Vertical staff located at lower end of box canyon. Channel. — Fairly permanent. Artificial control. — The flow from the reservoir is controlled by two 4-foot circular valves, and therefore the records, though they show the entire amount of the natural flow (less seepage and evaporation losses), do not represent the natural fluctuations. The total capacity of the reservoir is 17,000 acre-feet, of which about 7,000 acre-feet was utilized during 1912. Cooperation. — The records have been taken from the report of the State engineer, and were furnished by Mr. John E. Field, engineer for the San Luis Land and Irri- gation Co.

CONEJOS RIVER BASIN. GENERAL FEATURES. Conejos River rises on the eastern slope of the Conejos Mountains, on the southwestern boundary of San Luis region near, the head- waters of the Alamosa, nearly at the crest of the Continental Divide, flows northeastward as far as Platoro, then makes a sharp turn to the south following that direction for 10 miles, when it gradually bears to the eastward and then northward, entering the Kio Grande at Austin, about 6 miles below the mouth of the Alamosa. Just east of Conejos the river divides and flows to a point east of Manassa in two channels which there unite. Three miles above the mouth it again divides and enters the Rio Grande at two points a mile or more apart. Within the mountains the Conejos has many short tributaries, but after reaching the valley it receives only one tribu- tary of importance, the Rio San Antonio. The upper third of the Conejos basin lies in the mountains, with elevations reaching 12,000 feet. The detritus brought down in this portion of the basin has formed a long alluvial fan at the point of debouching into the valley. This fan is in part confined between the Mogotes Mountains and the San Luis Hills and in part extends south of the latter into New Mexico. Owing to the porous character of the material of the alluvial fan, it Is probable that there is some seepage loss in the flow of the Conejos after leaving the mountains. The river flows across the San Luis VaUey in a shallow channel, skirt- ing the western edge of the San Luis Hills. The mountains of the Conejos Range, which comprise the upper third of the area drained by the Conejos, are made up in their eastern slopes (adjacent to the valley) of alternations of gravel beds, ande- sitic flows, and rhyolitic tuffs cut through in places by dikes and the volcanic necks of centers of effusion. These flows incHne toward the valley with dips varying from 6° to 15° and extend under it. In the valley proper these flows are covered with a series of blue clays interstratified with sand beds, which yield flowing artesian water in many wells in the lower part of the drainage area. The rainfall on the Conejos Mountains is heavier than in any other part of the region drained by the Rio Grande. At Platoro (eleva- tion, 9,800) the mean precipitation is upward of 23 inches and at Cumbres (elevation, 10,015) it is about 26 inches. A large part of this precipitation is snowfall, which is a natural storage until May and June when its melting causes the high water. The precipita- tion rapidly decreases with the altitude, falling to about 8 inches iii the valley section of the drainage. The waters of the Conejos are extensively utihzed for irrigatior' in the valley, there being adjudicated decrees for appropriations of 3,476 second-feet by direct diversion. This amount is equal to the entire flow of the river during the height of the flood period. CONEJOS RIVEK BASIN. 863 GAGING STATION RECORDS. CONEJOS RIVER NEAR MOGOTE, COLO. Location. — At highway bridge near Mogote. Records available. — From September 1, 1899, to March 31, 1900, and from April 17, 1903, to October 31, 1905, at a station about 4 miles above Mogote; April 22 to June 21, 1906, and March 21, 1907, to October 5, 1911, at Jacob's ranch, 8 miles above Mogote. January 1, 1912, to September 30, 1913, at present site. Drainage area. — Not measured. Gage. — Staff gage, originally located at wagon bridge at Conejos, but moved to a point 500 feet below on November 5, 1899. The datum of the gage remained per- manent as long as used. At the station established in 1907 a chain gage was used, referred to the same datum as a rod gage used by Mr. Antoine Jacob during 1905 and 1906. This datum remained unchanged until the station was changed in 1911. Channel. — Fairly permanent at present site but shifting at original site. Discharge measurements. — Made from bridge. Winter flow. — Ice causes backwater during the winter months. Diversions. — There are court decrees for diversions of 3,476 second-feet from Conejos River, all but about 66 second-feet being diverted below the present station. Accuracy. — Data prior to 1903 too meager to permit estimates of daily discharge being made. From 1903 to 1905 conditions were favorable for estimates, which are considered fair; the estimates since 1907 are considered good and for some months even excellent. Cooperation. — During 1912 and 1913 station was maintained by the State engineer, who furnished the complete records. Discharge measurements of Conejos River near Mogote, Colo., in 1899-1913.

GENERAL FEATURES. Costilla Creek rises on the western slope of the Sangre de Cristo Range Gocally known as the Costilla Mountain) in the Sangre de Cristo grant, Taos County, N. Mex,; it first flows southward, then, making a sharp turn, flows northwest, entering Colorado near Cos- tilla; at Eastdale it turns to the southwest, again crosses into New Mexico, and joins the Rio Grande a few miles south of the Colorado- New Mexico line. It has no important tributaries and sends no water to the Rio Grande except during the spring high stage and after heavy rains. The upper part of the drainage area comprises the western slope of the Sangre de Cristo Mountains from which the greater part of the water supply is derived. The lower and by far greater part of the area is included in the Cerro Mesa, a smooth tract of land at a general elevation of 8,000 feet above sea level. Precipitation in the Costilla basin decreases from 23 inches or more at the crest of the Sangre de Cristo Mountains to 13 inches or less at the mouth. GAGING STATION RECORDS.

Rio Colorado drains an area lying on the western slope of the Sangre de Cristo Mountains in northern New Mexico. It rises in the south- eastern corner of T. 28 N., R. 14 E., at an elevation of nearly 10,000 feet above sea level, flows north for a distance of 6 miles, then turns and flows in a general westerly course to its junction with the Rio Grande, in sec. 17, T. 28 N., R. 12 E. Its principal tributaries are Bitter and Cabresto creeks from the north and Goose, Placer, Pioneer, and Columbine creeks from the south. Above Questa the country is mountainous, with elevations ranging from 8,000 feet at Questa to more than 10,000 feet at the divide. In this section the tributaries flow through narrow valleys, though the valley of the Colorado itself has gently sloping sides. Below Questa and north of the river the basm includes the southern end of a large smooth mesa known as Cerro Mesa, but south of the Colorado the surface is more broken. The mean annual precipitation in the upper part of the drainage basin, on the western slope of the mountain range, is 24 inches or more; at the mouth of the river, on the mesa, it is about 13 inches. W. W. Follett, in his report on the ''Distribution of waters of the Rio Grande," states that irrigation is carried on extensively in the southern portion of the Cerro Mesa, in the vicinity of Questa. There are no reservoirs in operation in the basin of the Rio Colorado. GAGING STATION RECORDS RIO COLORADO ABOVE QUESTA, N. MEX. Location. — Five miles above Questa, in Taos County, and about 5 miles above Cabresto Creek, the nearest tributary, near sec. 2, T. 28 N., R. 13 E. Records available. — April 5, 1910, to September 4, 1911, when the station was discontinued. Drainage area. — Not measured. Gage. — Vertical staff; table of gage heights for 1910 refer to a gage at a different datum and location. Channel. — Apparently permanent. Discharge measurements. — Made by wading. Winter flow. — No information available. Diversions. — No data. Accuracy.— Owing to the small number of gage heights, satisfactory estimates can not be made. Cooperation. — Station maintained in cooperation with the United States Forest Service and the State engineer. 1 Also known as Red River.

EIO COLORADO BELOW QUESTA, N. MEX. Location. — Two miles below Questa, at the head of Lower Canyon, near sec. 1, T. 28 N., R. 12 E., below all important tributaries, the nearest one above being Cabresto Creek. Records available. — April 8, 1910, to September 30, 1913. Drainage area. — Not measured. Gage. — Vertical staff. Channel. — Shifting during high water. Discharge measurements. — Made by wading or from car and cable, Winter flovr. — Slightly affected by ice during December and January of each year. Diversions. — There are no diversions below, but, for several miles above, diversions are made for irrigation. Accuracy. — Owing to radical changes in the stream bed, estimates of discharge were not made in 1910 and 1911. The estimates made during the first part of 1912 can not be considered better than fair, but those thereafter can be rated as good. Cooperation. — Station maintained in cooperation with the United States Reclama- tion Service and the State engineer. Discharge measurements of Rio Colorado below Questa, N. Mex., in 1910-1913. Date.

RIO HONDO BASIN. GENERAL FEATURES. Rio Hondo, one of the comparatively few perennial tributaries of the Rio Grande, rises near the crest of the Taos Mountains — the southern extension of the Sangre de Cristo Range — and takes a general westerly course to its junction with the Rio Grande about sec. 31, T. 27 N., R. 12 E. Its chief tributaries are Long Canyon, Lake Creek, South Fork, and Turkey Creek. The drainage of the Rio Hondo is mountainous for the most part. The Hondo reaches 10,000 feet, while of its tributaries Long Canyon nearly reaches 11,000, Lake Fork 12,000, and the South Fork 10,000 feet, insuring a supply of water from the snows of the higher moun- tains. In the lower half of the area the altitude ranges between 8,000 and 9,000 feet. No records have been taken within the Rio Hondo basin, but from records of neighboring areas it is probable that the mean annual pre- cipitation for the lower portion of the basin is between 14 and 15 inches, while in the upper portion it may reach 24 inches, owing to the greater altitude. In FoUett's report on the "Distribution of the waters of the Rio Grande" it was stated that prior to 1896 there were six irrigation ditches having a total capacity of 69 second-feet taking water from the Rio Hondo for irrigation in the valley below Cristone. GAGING STATION RECORDS. RIO HONDO NEAR ARROYO HONDO, N. MEX. liocation. — At highway bridge at Dunn's ranch, 200 yards above the mouth of the stream, 1 mile west of Arroyo Hondo post office, near sec. 31, T. 27 N., R. 12 E. No tributary between station and mouth. Records available. — April 8, 1910, to September 30, 1913. Drainage area. — Not measured. Gage. — Inclined staff. Channel. — Shifting. Discharge measurements. — Made by wading at low stages and from a bridge at high stages. Winter flow. — Ice causes slight backwater during portions of the winter months. Diversions. — None below, but several diversions for irrigation are made above. Accuracy. — Owing to the discrepancy in the gage heights recorded by the hydrographer and the observer, no estimates of discharge were made in 1911 and the first part of 1912. The estimates for the last part of 1912 and those for 1913 are considered Cooperation. — Station maintained in cooperation with the United States Reclama- tion Service and the State engineer.

RIO TAOS BASIN. GENERAL FEATURES. Rio Taos is formed by the junction of the Rio Pueblo, Rio Fer- nando, and Rio Grande del Rancho near Los Cordovas, a few miles west of Taos. The headwater streams rise on the western slope of the southern extension of the Sangre de Cristo range, known locally as the Taos Mountains. The general course of the streams is west- ward, and below the junction Rio Taos flows southwestward, joining the Rio Grande about 7 miles below the junction. The chief tribu- tary of Rio Pueblo is Rio Lucero. Rio Fernando has no important tributary. The principal tributaries of the Rio Grande del Rancho are Rio Chiquito and Arroyo Miranda. Above the junction of the principal headwater streams the area is mountainous, elevations ranging between 7,000 and 10,000 feet or higher, and the streams flow in canyons. Below the junction Rio Taos crosses a level mesa, which is 7,000 feet in altitude and is known as Taos Valley. At the crest of the mountains the mean annual precipitation is 24 inches or more, but it decreases rapidly with decrease in altitude, being only about 14 mches at Taos and throughout the lower part of the basin. The precipitation in the mountains is largely in the form of snow, which is the chief source of supply of the stream. In his report on the Rio Grande, issued in 1896, W. W. Follett states that the area of irrigable land in Taos Valley is fully 40,000 acres, but that the water supply is only sufiicient for about half this land, and it has been utihzed for the last 50 years or more. At the time the report was issued it was estimated that ditches having a total capacity of 316 second-feet diverted water from Rio Taos and its tributaries. GAGING STATION RECORDS. RIO PUEBLO DE TAOS NEAR TAOS, N. MEX. Location. — Two miles above Taos Pueblo, 4J miles northeast of Taos, at Glorietta Grove, near sec. 2, T. 25 N., K. 13 E. A number of intermittent tributaries enter above and below the station. Records available. — March 12, 1910, to September 30, 1913. Gage height records prior to December, 1910, are fragmentary and hot published. Drainage area. — Not measured. Gage. — Automatic recording. Installed by the United States Indian Service Decem- ber 19, 1910. A vertical staff gage was installed first, but was destroyed before July 12, 1910. On October 12, 1910, a new gage was installed which was referred to a datum 0.27 foot lower than the original. The automatic gage was referred to the datum of the second gage. Channel. — Somewhat shifting, especially during high stages. Discharge measurements. — Made by wading. Winter flow. — Ice causes backwater during the winter period. RIO TAOS BASIN. 391 Diversions. — None above this statiou, but several are made just below. Accuracy. — The few discharge measurements indicate that there was not much shift during 1911, and therefore the estimates may be considered fairly good. The esti- mates for 1912 are fragmentary and can only be considered fair. Those for 1913 may be considered good. Cooperation. — Station maintained in cooperation with the United States Forest Service, United States Indian Service, and State engineer. Discharge measurements of Rio Pueblo de Taos near Taos, N.

CHAMA RIVER BASIN. GENERAL FEATURES. Chama River rises on the western slope of the Conejos Mountains, a few miles north of the Colorado-New Mexico line, at an approximate elevation of 12,000 feet above sea level, flows in a general southerly course which finally becomes southeasterly, and enters the Rio Grande at Chamita, about 30 miles north of Santa Fe, in the Espanola Valley. It has a number of short tributaries, the most important being the Brazos, Horn, GaUinas, Cebolla, Puerco, and Caliente. The drainage area is bounded on the east by that of the Conejos River, which merges with the Black Mesa, and on the west by the Continental Divide. It consists chiefly of high plateaus and moun- tain ranges. The upper portion of the river above the mouth of the Brazos is in a canyon, but between the Brazos and the Nutritus the river flows through a low fertile mesa. Below this point it again flows through an ahuost continuous canyon to Abiquiu, where it enters the Chama Valley which continues to the mouth. From its mouth as far up as Gallinas Creek the Chama itself and all its tributaries are muddy, but above the Gallinas the water is somewhat clearer, especially that of the Brazos. All the tributaries that enter below the Cebolla, except the Puerco, have broad sandy channels near their mouths, and in this part of their courses lose much of their water by seepage and evaporation. The loss in the Caliente, Oso, El Rito, Lower Canyones, and Horn rivers is especially large.^ The chief source of the perennial flow of the streams is the snow that falls on the western slope of the Conejos Range. At Cumbres (elevation 10,015) on the eastern slope the annual precipitation is upward of 25 inches, and as the prevailing winds are from the west 1 For seepage in the Chama itself see p. 690. 408 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. it is probable that on the western slope the precipitation is even more. The only record in the upper Chama Basin is at Chama (elevation 7;848) where the mean precipitation is 23 inches. South from the source the precipitation decreases, being about 15 inches at the mouth of the Gallinas, 13 inches at Abiquiu, and 12 inches at the mouth. Much of the precipitation of the lower portion of the basin comes in the form of violent rains which subject the river to sudden floods. Irrigation is carried on extensively in the valleys bordering the Chama and some of its tributaries. FoUett, in his report on the "Distribution of the waters of the Rio Grande," states that prior to 1896 there were ditches having a total capacity of 1,141 second-feet diverting water from the Chama and its tributaries, of which 352 second-feet was the total capacity of ditches diverting water from the Chama itself.

Location. — At the Denver & Rio Grande Railroad bridge, about half a mile northeast of Chama, 2 miles above the mouth of Little Chama River, in see. 13, T. 31 N., R. 3 E. Records available. — September 23, 1912, to September 30, 1913. Drainage area. — Not measured. Gage. — Vertical staff. Channel. — Permanent at low stages, but subject to a shift during flood stages. Discharge measurements. — Wading at low stages and from a bridge during flood stages. Winter flow. — Ice effect during the winter months. Diversions. — Very little water is taken out for irrigation above this point; conse- quently the discharge at this point approximates the natural run-off. Accuracy. — The estimates can be considered good. Cooperation. — Maintained in cooperation with the Tierra Amarilla Land Grant Co., Chama, N. Mex., and the State engineer.

The area drained by the Kio Puerco Hes west of the Eio Grande between the basin of the Jemez on the north and the Salado on the south. Rio Puerco rises on the western slope of the Jemez Mountains in the northern part of Sandoval County and flows in a general southerly direction to its junction with the Rio Grande at La Joya in the Belen Valley. Aside from the violent storms which furnish the waters lor the sudden floods to which the river is subject, almost the entire water supply is received from the Jemez Mountains. The only tributary of importance is San Jose River, known in its upper portion as Bluewater Creek, which during the spring has considerable flow. The soil over which the Puerco flows is so porous that except at times of violent storms there is no flow at the mouth, and therefore the Rio Puerco is only a flood-water tributary of the Rio Grande. During flood a great amount of silt is carried in the river. FoUett, 438 WATER RESOURCES OP RIO GRANDE BASIN, 1888-1913, in his report on the Rio Grande, states that this may reach as high as 15 per cent. The surface of the basin is much broken and comprises in the north- western half the barren Chama Mesa which ends at the San Mateo Mountains on the south. The general elevation of this mesa is approximately 7,000 feet. South of the San Mateo Mountains is the valley of the San Jose or Bluewater Creek. This stream rises in the Zuni Mountains on the Continental Divide, leaves them near Blue- water, and flows through a valley having a rich alluvial soil washed down' from the mountains. The valley of the Puerco itself is also alluvial and has been formed in the same way. At the mouth of of the Puerco the elevation is about 4,700 feet, indicating a compara- tively heavy fall throughout the course of the river. The lines of equal precipitation on the map (PI. Ill) indicate that for the portion of New Mexico adjacent to the Puerco drainage the mean precipitation is about 14 inches for the northern and western edges of this area, except on the crest of the Jemez Mountains, which rise some 2,000 feet or more above the general mesa level. Although no records are available, it is probable that precipitation is somewhat greater at the higher altitudes than on the mesa^ and it decreases to approximately 10 inches at the mouth of the river. Little of this precipitation is in the form of snow ; it occurs chiefly as violent storms which may produce severe floods. Within the boundaries of the basin there are many areas of considerable size which do not send surface streams to the Puerco or its tributaries owing to their broken topog- graphy and porous soil. These areas are too small and indefinite to be shown on the map with the large nonproducing areas. The alluvial valleys of the Puerco, San Jose, and their tributaries are irrigated as extensively as the smaU water supply will permit. In his Rio Grande report Follett states that prior to 1896 there were ditches having a combined capacity of 580 second-feet diverting water from the Puerco and its tributaries. A storage reservoir with a capacity of 20,000 acre-feet, which can be increased to 70,000, has been built on Bluewater Creek in T. 12 N., R. 12 W., for irrigation, but the water supply at this point is so small that the effect of the reservoir on the flow of the Bluewater is small.

Pecos River, one of the most important tributaries of the lower Rio Grande, drains an area comprismg approximately 32,000 square miles and extending from the Taos Mountains in northern New Mex- ico to the southern edge of the western panhandle region in Texas. Its source is on the eastern slope of the Santa Fe Range in the extreme western corner of Mora County, at an elevation of 11,000 feet, and its course is southward nearly to Punta Pajarita, thence southeastward to the southeast corner of Guadalupe County, thence southward again to Carlsbad, and then once more southeastward to its junction with the Rio Grande at Moorhead, Valverde County, Tex. Except for some of the upper tributaries the branches of the Pecos are inter- mittent, though at times they carry large floods. The chief tributa- ries are Rio de la Vaca, Rio Tecolote, Gallinas River, Canyon Blanco, Pentado Canyon, Alamo Gordo Creek, Salt Creek, Felix, Penasco, Seven Rivers, Delaware, Toyah, and Comanche creeks. Below Fort Sumner there are no important tributaries from the east, as the boundary of effective surface drainage of the Pecos parallels the river at a distance of 50 miles. The few streams in this section rise in the edge of the high plains but lose their waters in the porous soil within a few miles. Many of the streams in the western portion of the basm sink before reaching the Pecos, and it is probable that the streams actually reaching the Pecos lose much water by seepage after leaving the mountains. The upper Pecos flows through narrow valleys and deeply cut gorges nearly down to Fort Sumner, and in this portion of the basin the elevations range from 4,500 feet to 11,000 feet above sea level. Below Fort Sumner the canyon-like walls of the Pecos are replaced by low rolling hills and at Roswell the gradation from the flood plains to the rolling prairie of the lower part of the drainage basin is imper- ceptible. Arroyos and gulches are rare, and canyons are practically unknown. Elevations in the lower section of the basm range from 1,000 feet at the mouth to 4,500 feet near the foothills. The distribution of precipitation throughout the Pecos basin is somewhat peculiar. Near the source of the river there is a very small area in which the mean annual precipitation is 20 mches or more, but, as shown on the map (PI. Ill), the rate drops to 15 inches at Anton Chico and less than 13 inches at Santa Rosa. From this point to Carlsbad there is a narrow strip coinciding practically with the imme- diate valley of the Pecos where the precipitation is between 12 and 13 inches, and east and west of this narrow area it increases to 15 inches or more. Below Carlsbad the increase is fairly uniform to 19 inches at the mouth. Except on the mountains in the upper section of the PECOS RIVER BASIN. 453 basin, where much of it occurs as snow, by far the greater part of the precipitation is the rain of the summer storms. The Carlsbad project of the United States Reclamation Service irri- gates about 20,000 acres in the vicinity of Carlsbad. The irrigation plan provides for the storage of water in Lake McMillan on the Pecos near Lakewood, and in a storage and distributing reservoir on the same river near Carlsbad, controlled by the Avalon dam, and the diversion of water from the Avalon reservoir into a canal system watering lands on both sides in the vicinity of Carlsbad. The two reservoirs have a combined capacity of 72,000 acre-feet, thus exerting a marked effect on the flow of the Pecos below Carlsbad. Irrigation is also extensively carried on in other sections of the Pecos Valley, especially in the vicinity of Pecos, Tex. THE PECOS FLOOD OF 1904.^ Late in September, 1904 — chiefly on the 28th and 29th — a remark- ably heavy rainfall occurred in the northern part of the eastern half of New Mexico and in an area about 125 miles long and 50 miles wide lying just west of Roswell. Arabella and Hot Springs, N. Mex., seemed to be the two centers of the greatest precipitation in the Pecos Valley basin. An observer near the headwaters of Pecos River says: Between the 26th and 30th of September, 1904, very heavy steady rains fell over nearly the entire Ten-itory. The greatest damage occurred on Thursday morning, September 29, over the eastern slopes of the mountaijis and along the valleys and lowlands of the northern portion, but the floods were nearly as destructive over the eastern slope of the several moimtain ranges in the southwest portion and over the Hondo in the southeast. In an area 500 by 300 mUes reports show that a rainfall of 3 to 7 inches fell within the space of 24 to 48 hours. The flood waters reached Roswell, N. Mex., on September 29, and in the evening of that day the water broke over the banks of the Hondo at 8 p. m., and in 15 mniutes the main street of that city was under water and the dike erected for the protection of the city swept away, Ukewise the railroad bridge north of the city. The flood at this place lasted only four days, but lines of communications were so damaged that no mail was delivered until October 10. The opera house and about 15 dwellings were destroyed. The crest of the flood reached Carlsbad, N. Mex., at 3 a. m. October 2. The irrigation works were badly damaged, the cotton gin and all bridges on Pecos River were swept away, and the railway track for miles up and down the river was submerged. On October 3 the water reached a height of 9 feet on the United States Geological Survey gage 6 miles above Pecos, N. Mex., and it continued to rise slowly for about 48 hours. This rise was so gradual that it could scarcely be noted from hour to hour. At 10 p. m. on October 4 it began to rise on the gage at the rate of about 1 foot an ' Abstracted from United States Geol. Survey Water-Supply Paper 132, pp. 111-llG, 1905. 454 WATEE EESOURCES OP EIO GEANDE BASIN, 1888-1913. hour, and about this time four leaks occurred in the levees of the Barstow Irrigation Co., 3^ miles above the flume, on the west side of the river, which were built to protect the West Valley [system from flood waters. This water soon entered the canals, and by 3 a, m. October 5 the canals were filled and soon overflowed so rapidly that many breaks were made in the West Valley canals. Daybreak of October 5 showed a sluggish flood of murky red and gray spread from half a mile to 2 J miles in width on either side of the river. The cur- rent in the main channel of the river did not seem as boisterous as on the previous days, but at many points along the river currents were running out over the banks into and through the surrounding flats, covering the whole country to the foothills from 2 to 4 feet deep. At 8 a. m., with 19 feet by gage, the flume gave two little snaps, its center bowed downstream, the ends tore loose, the flume slowly rose, emptied its water, broke in two, and the two hulks floated downstream. These two parts, each about 100 feet in length, finally grounded, one about 1| miles below the flume and the other at a point about 5 miles below where it had caught on the banks of the river and formed a perfect bridge across the river channel. This section of the flume held this position till the gage read 10.50, but on the night of October 12 a small rise raised the water on the gage to 14, and in the meantime drift had caught above this part of the flume, and the added force carried the broken flume on down the river to the highway bridge east of Pecos City, where it passed under in some almost miraculous manner and caught against the railroad bridge a few hundred feet below. It was soon wrecked sufficiently to allow it to pass under this bridge. It may be remarked here that these two bridges (about 1 mile east of Pecos City) were the only structures that remained across Pecos River during the flood. This was due to the fact that at high water a large portion of the flood waters (perhaps half) flow out on the east side of the river channel and through a quarter-mile trestle work on the Texas & Pacific Railway. On October 15 the gage at the flume read 9 feet, thus showing that the flood that swept through Roswell, N". Mex., in about three days had spread out enough to make some 10 days of extremely high water near Pecos. About October 20 most of the outlaying water had drained back and it had left a deposit of reddish clay and fine sand where the water was sluggish and coarse sand where the water was swift. The depth of this deposit varied from 0.20 to 0.40 feet, except at certain isolated points where a deposit of over 1 foot was left. Above the main canal of the Barstow Irrigation Co., on the east side of the river, the water reached a depth of 4 feet, and it required a period of two weeks to drain this water off. After the flume went out on October 5 the water level dropped about 0.30 foot, showing that the flume had little effect on holding PECOS RIVER BASIN. 455 the water back. On tlie west side of the river two-thirds of the alfalfa was killed by the flood and about 50 per cent of the cotton was lost. Out of 900 acres 700 were flooded. On the east side some thousand acres were heavily flooded and as much more lightly flooded. The sorghum was injured very slightly, but from 25 to 50 per cent of the cotton heavily flooded was lost. Very few of the plants were killed, but the bolls were so soaked that they soured and were ruined. This flood did its greatest damage at its beginning in New Mexico, and the damage became less as it approached the Rio Grande. The flood was caused by concentrated floods in two localities in New Mexico. Below Carlsbad the rainfall was moderate, and it decreased in intensity to the south. GAGING STATION RECORDS. PECOS RIVER NEAR COWLES, N. MEX. Location. — At highway bridge about sec. 28, T. 18 N., R. 12 E., three-fourths of a mile below the old Cowles post office, 5 miles below the present Cowles post office, which is at Windsor, midway between the Espiritu Santo and Mora Creeks, about half a mile below the mouth of Willow Creek. Records available.— March 9, 1910, to September 30, 1913. Drainage area. — Not measured. Gage. — Automatic recording. A gage of the Bristol type was installed June 5, 1912, in place of a Friez automatic gage. On April 9, 1913, the Bristol gage was removed and on April 18, 1913, a Friez gage was reinstalled. These gages were all referred to the same datum. Channel. — Fairly permanent except dining high water, when it may shift slightly. Discharge measurements. — Made from bridge during high water and by wading at ordinary stages. Winter flow. — Ice causes back water during a portion of the winter months. Accuracy. — Conditions are favorable for accurate results and the record should be reliable. The estimates can be considered good, but on account of doubtful gage heights estimates were not made from August to December, 1912. Cooperation. — Maintained in cooperation with Mr. E. H. Fisher, Albuquerque, N. Mex., and the State engineer. Discharge measurements of Pecos River near Cowles, N. Mex., in 1910-1913. Date. 1910. Mar. 7 10 Apr. 23 23 June 9 AuR. 20 Sept. 7 Oct. 31 1911.

PECOS RIVER AT SANTA ROSA, N. MEX. Location. — Originally established at the Chicago, Rock Island & Pacific Railway bridge at Santa Rosa. When the station was reestablished in 1910 it was moved about 400 feet downstream to the highway bridge, 1 mile above the mouth of Rio Agua Negra Chiquita, in sec. 11, T. 8 N., R. 21 E. Records available.— May 5, 1903, to December 31, 1906; February 1, 1910, to July 31, 1911; September 21, 1912, to September 30, 1913. Drainage area. — 2,780 miles (measured from Land Office map). Gage. — The original gage was a staff bolted to the bridge pier. A chain gage is used at the present station. Channel. — Very shifting. Discharge measurements. — At the original station, made from car and cable and by wading; at the present one, from the bridge and by wading. Winter flow. — Practically no ice at this station. Flood stage. — During the period covered by the records there was but one eerioua flood, which occurred September 29 and 30, 1904, when the river reached a recorded stage of 23.0 feet. Accuracy. — Owing to the shifting character of the stream and insufficient measure- ments, no estimates of discharge were made prior to 1906. Since that date esti- mates are available which are considered reliable. Cooperation. — The United States Reclamation Service maintained the station from 1904 to 1906, but since 1910 it has been maintained in cooperation with the State engineer. 41823° — wsp 358 — 15- -30 466 WATER EESOUKCES OF EIO GEAFDE BASIN, 1888-1913.

PECOS RIVER NEAR FORT SUMNER, N. MEX. Location. — At Arinosa, 4 miles northwest of Fort Sumner and 3J miles above the Atchison, Topeka & Santa Fe Railway bridge, in sec. 12, T. 3 N., R. 25 E. The nearest tributary is an arroyo entering from the west a short distance below. Records available.— June 12, 1904, to February 28, 1910; September 16, 1912, to September 30, 1913. Drainage area. — Approximately 5,300 square miles. Gage. — Original gage, a vertical staff. On July 5, 1905, an inclined staff was estab- lished at the present location, 1 mile downstream. The datum of the latter gage has remained unchanged. Channel. — Very shifting. Discharge measurements. — Prior to 1912, flood discharge was measured by floats and estimates from elope measurements, using Kutter's formula. Low-water measurements were made by wading. Since 1912 high-water measurements have been made from car and cable. Winter fl.ow. — Slush ice sometimes forms at the station and thin ice forms along the edges of the river, but results are not greatly affected by ice. Accuracy. — Owing to the very shifting channel, the estimates can only be considered approximate except those for 1910, 1912, and 1913, which are fair. Cooperation. — During 1912 and 1913, station maintained in cooperation with the State engineer. Discharge measurements of Pecos Riverncar Fort Suvaner, N. Mew, in 1904-1910, 1912-13. Date.

PECOS RIVER NEAR DAYTON, N. MEX. Location. — Three miles east of Dayton, in T. 18 S., R. 26 E., half a mile above the mouth of Penasco River. Records available.— March 24, 1905, to September 30, 1913. Drainag-e area. — Not measured. Gage. — Vertical staff. The original gage, which was located 100 feet below the mouth of the Penasco River, was washed out September 6, 1905, and was relocated Sep- tember 7, 1905, half a mile upstream. Datum unchanged since then. Channel. — Shifting during high water. Discharge measurements.- — Made from car and cable. Winter flow. — Ice has little effect on the relation of gage height to discharge. Diversions. — The station is about 10 miles above the dam at the outlet of Lake McMillan, one of the reservoirs in the United States Reclamation Service Carlsbad project, which irrigates about 20,000 acres in the vicinity of Carlsbad. Accuracy. — Owing to the shifting character of the stream, the estimates can not be considered in general better than fair. Those for 1912 and 1913 are, however, good. Cooperation. — Since 1908 station maintained by the United States Reclamation Service, which furnished the field data. PECOS RIVER BASIN. 489 Discharge measurements of Pecos River near Dayton, N.

Location. — Three miles southeast of Lakewood, half a mUe below the McMillan reser- voir dam, in sec. 11, T. 20 S., R. 26 E.; no tributary between the .station and the reservoir; Seven Rivers enters 3 miles below. Records available. — January 11, 1906, to December 16, 1911, when the station was discontinued. Drainage area. — Not measured. Gage. — Inclined staff. The original gage was at the lower side of the dam, but was moved to a point near the lower end of the outlet canal February 8, 1906. On May 8, 1906, it was moved to its final location. Channel. — Shifting. Discharge measurements. — Made from car and cable a quarter of a mile above the railway bridge of the Eastern Railway of New Mexico. Winter flow. — Not affected by ice. Diversions. — Lake ^IcMillan is the upper reservoir in the Carlsbad project of the United States Reclamation Service. Although the flow from the lake passes the station, the flow over the flood spillways reaches the river below the station and is not recorded. Accuracy. — Although the channel is shifting, sufficient discharge measurements were made to allow estimates of discharge, ha\'ing a fair degree of accuracy, to be made from 1906 to 1909. No estimates were made for 1910 and 1911. Cooperation. — Station maintained by the United States Reclamation Service, which furnished the field data.

PECOS RIVER AT AVALON, X. MEX. Location. — Half a mile below the Avalon dam, in sec. 11, T. 21 S., R. 26 E., and 6 miles north of Carlsbad. Records available. — January 6, 1906, to March 16, 1907. From June 18 to October 10, 1891; April 1 to November 30, 1895; January 1, 1899, to December 31, 1903; records of the flow through the headgates and over the spillway of the Avalon dam were compiled by the Pecos Irrigation Co. These records, together with estimates of flow used in irrigation during 1904, were published in the Fourth Annual Report of the United States Reclamation Ser\'ice, page 271, from which the records here- with have been taken. Drainage area. — Not measaired. Gage. — Vertical staff. Channel. — Fairly permanent. Discharge measurements. — Made from boat and cable. 508 WATER EESOUECES OF RIO GRANDE BASIN, 1888-1913. Controlled, flow. — In addition to the storage afforded in Lake McMillan (see Pecos at Lakewood), Avalon reservoir, which acted as the distributor for Lake McMillan prior to October, 1904, when its dam was washed out, had additional storage capacity of 6,300 acre-feet when built. Accuracy. — Conditions were favorable for accurate results for 1906 and 1907 and the records are considered reliable.

MARGUERETTA FLUME NEAR PECOS, TEX. Location. — At the crossing of the Barstow Irrigation Co.'s canal over Pecos River, about 6 miles above Pecos and 3 miles below the head gates of the canal. Records available. — ^January 1 to December 31, 1898; January 1, 1900, to June 30, 1907. Gage. — Vertical staff located at the east end of the flume, having its zero at the bottom of the flume. The gage was originally located at the west end of the flume, but as water was sometimes wasted into the river just beyond this point, the gage heights did not at all times represent the amount used for irrigation. For that reason the gage was moved to the east end November 17, 1905. Channel. — Shifting, due to deposits of silt at different times. Discharge measurements. — Made at the east end of the flume. Diversions. — About 10 second-feet are diverted into the West Valley ditch above the flume and at times water is wasted from the flume into the Pecos above the station, so the records subsequent to November 17, 1905, do not represent the amount of water actually diverted, but the amount available for irrigation below the crossing. Prior to that date, except for the West Valley ditch, the records represent the amount of water diverted. Accuracy. — Owing to the shifts of channel the estimates in general can not be con- sidered better than fair. 41823°— wsp 358 — 15 34 530 WATER EESOUKCES OF EIO GEANDE BASIN, 1888-1913.

Location. — Immediately above the high bridge of the Southern Pacific Railroad near Moorhead. No tributary between the station and the mouth. Records available. — May 1, 1900, to September 30, 1913. (Also gage heights for 1898.) Drainage area. — Not measured. Gage. — Vertical staff bolted to bridge pier; read with field glasses from the top of the cliff. Nothing is known regarding the gage used in 1898. Discharge measurements. — Made from car and cable. Channel. — Shifting. Diversions. — The records at this station do not represent the natural run-off, as water is diverted extensively for irrigation. Floods. — The highest known flood occurred April 6, WOO, and reached a stage of 35.75 feet upon the gage subsequently established. The floods of the lower Pecos are of a very flashy character. Accuracy. — Owing to the shifting channel conditions very frequent discharge meas- urements are made, and the estimates of daily discharge based almost entirely on these. Cooperation. — Station maintained by the United States section of the International Water Commission, by whom the records are furnished.

GENERAL FEATURES. Gallinas River, one of the most important tributaries of the upper Pecos, rises on the eastern slope of the Santa Fe Mountains, about 20 miles northwest of Las Vegas, flows in a general southeasterly course, and enters Pecos River at La Junta, on the northern edge of Guadalupe County. It receives no important tributaries. The Gallinas flows through narrow valleys and canyons from its source at 9,000 feet elevation to its mouth, except in a stretch about 10 miles long in its lower course, where it flows across a comparatively open valley. The entire basin is rough, the mountains of the head- water region giving way to mesas deeply cut by drainage lines. Below Las Vegas the Gallinas receives little if any drainage from the region to the north, as this is devoid of drainage lines and has many sinks. From this large noncontributing area and the almost entire absence of tributaries, it is evident that the chief source of the water supply is the Santa Fe Mountains. The mean annual precipitation at the headwaters of the Gallinas, in the Santa Fe Mountains, is 20 inches or more, and it decreases to PECOS RIVER BASIN. 561 18 inches at Las Vegas and 13 inches at the mouth. Except on the headwaters, the precipitation occurs chiefly as rain during the summer months. In 1903 the United States Reclamation Service began the investi- gation of a project to irrigate 10,000 acres in the vicinity of Las Vegas. It was proposed to utiUze a reservoir site lying 5 miles north of Las ^>gas and 2 miles east of Hot Springs. The reservoir, which would have a capacity of 38,000 acre-feet, was to be suppUed with water by diverting the flood run-off from Sapello, Gallinas, San Gui- jucla, and Arroyo Pecos creeks. Further than making the surveys and maintaining records of flow, nothing has been done by the Recla- mation Service. GAGING STATION RECORDS. GALLINAS RIVER NEAR LAS VEGAS, N. MEX. Location.— At Las Vegas Hot Springs, 6 miles northwest of Las Vegas, near sec. 1, T. 16 N., R. 15 E. No tributaries between the station and Las Vegas nor for several miles above. Records available.— August 13, 1903, to May 31, 1912; December 1, 1912, to Sep- tember 30, 1913. Drainage area. — 89 square miles (measured from topographic sheets). Gage. — Vertical staff, 600 feet above the power house footbridge, installed to replace the original gage which was washed out September 29, 1904; datum of new gage 0.71 foot lower than that of the original gage. Channel. — Somewhat shifting during high water. Discharge measurements. — Made from the footbridge during high water and by wading at ordinary stages. Winter flow. — Gage heights unaffected by ice, as channel is kept open by the hot springs. Diversions. — A short distance above the station is a timber dam which forms a pond from which ice is cut. This dam does not control the flow in any way. A small amount of water is diverted at this point for storage by the Agua Pura Co., which furnishes Las Vegas and the Santa Fe Railway ^"ith water. A mile below the station is a dam which diverts the flood flow of the Gallinas to the San Guijuela Basin. The fall of the river is so heavy that the gaging station is above the influence of this dam. During the last of February, 1913, the Agua Pura Co. began diverting water 1^ miles above the station. Accuracy. — Although the river is somewhat shifting at this station, it is believed that the estimates of discharge are reliable. Cooperation. — Diu"ing 1912 and 1913 station maintained in cooperation ■with the State engineer. 41823° — wsp :!58^15 36 562 WATER EESOURCES OF EIO GRANDE BASIN, 1888-1913.

HONDO RIVER. BASIN. GENERAL FEATURES. Hondo River, one of the intermittent tributaries of the Pecos, is formed by the junction of the Rio Ruidoso and Bonito Creek in the northern part of T. 11 S., R. 17 E. It flows eastward and enters the Pecos 6 miles southeast of Roswell. The chief tributaries are North Spring and Berrendo rivers from the north, and South Spring River from the south. The basin comprises the eastern slope of the Sierra Blancas, where elevations reach 12,000 feet above sea level, and the southern slope of the Sierra Capitan, whose altitude is somewhat lower. On the head- waters of tributary streams there are a number of lakes which are fed by springs, and thus insure a perennial flow in the upper part of the Hondo. Farther down the water is diverted to such an extent for irrigation that there is no flow in the lower river except during floods. The river also probably loses much water by seepage through the PECOS EIVER BASIN. 579 porous soil of the Pecos Valley, over wliich it flows in its lower course. So porous is the soil that ji iniiubcr of streams that should be tributary to the upper stretch of the Hondo lose their waters in the ground before reaching it. The lines of equal precipitation for the southeastern part of New Mexico (PI. Ill) indicate that the mean annual precipitation in the mountains at the upper end of the basin is approximately 23 inches. It rapidly decreases with the altitude, being about 16 inches at Fort Stanton and 12 inches at Roswell, near the mouth. The precipitation occurs cluefly during the summer months, although there is a light snowfall in -the mountains. Irrigation has been carried on extensively in the Hondo basin, especially on the headwater streams, for many years. The United States Reclamation Service has constructed a system, known as the Hondo project, wliich is designed to store the flood waters in Hondo reservoir, located in T. 11 S., Rs. 22 and 23 E., for use in irrigating 10,000 acres in the vicinity of RosweU. The reservoir has a capacity of 40,000 acre-feet. GAGING STATION RECORDS. HONDO RIVER AT HONDO RESERVOIR SITE, NEW MEXICO. Location. — Just below the diversion dam for the Hondo reservoir, in sec. 34, T. 11 S., R. 22 E., 12 miles southwest. of Roswell. No tributaries within several miles. Records available. — June 7, 1903, to December 31, 1906. Drainage area. — Not measured. Gage. — Inclined staff; datum unchanged. Channel. — Shifting. Discharge measurements. — Made from near-by footbridge. Diversions. — The normal flow is diverted for irrigation above the station, leaving only the flood flow available for storage in Hondo reservoir. Storage. — Hondo reservoir has a capacity of 40,000 acre-feet and is designed to store the flood waters of the river. As it was not completed until 1906, it is possible that prior to that year little, if any, water was stored during the period covered by the records. Accuracy. — Owing to the shifting channel and insufiicient measurements, estimates of daily or monthly discharge for years prior to 1906 have not been made. P^or that year the estimates can be considered only approximate. '580 WATER EESOUECES OF EIO GEANDE BASIN, 1888-1913.

HONDO RIVER AT ROSWELL, N. MEX. Location. — At the bridge at the intersection of Main and Vegas Streets, Roswell. Between Roswell and the mouth the Hondo receives North and South Spring rivers, which are fed by springs at their source. Records available.— June 8, 1903, to February 28, 1906. Drainage area. — Not measured. G-age. — Inclined staff. A new gage was set August 8, 1905, and it is not known whether it was referred to the original datum. This gage was lowered 3 feet February 8, 1906, and all gage heights for 1906 were referred to the later datum. Channel. — Shifting. Discharge measurements.^ — Made from bridge. Diversions. — The normal flow is diverted for irrigation above the station. Storage. — Hondo reservoir has a capacity of 40,000 acre-feet and is designed to store the flood waters of the river. As it was not completed until 1906 it is possible that prior to that year little if any water was stored during the period covered by the records. Accuracy. — Owing to insufiicient data, estimates of daily and monthly discharge have not been made for periods prior to 1906, and estimates for subsequent periods are only approximate.

PENASCO RIVER BASIN. GENERAL FEATURES. Penasco River, an. intermittent tributary of the Pecos, rises high on the eastern slope of the Sacramento Mountains and takes an east- erly course to the Pecos, which it enters near Dayton. The tribu- taries are chiefly confined, to the upper portion of the basin, except Bluewater Creek, which enters near the Chaves-Eddy County line. The principal tributaries are Elk and Chiquito creeks. The topography of the Penasco basin is similar to that of the Hondo, the upper portion including the eastern slope of the Sacra- 590 WATER EESOUECES OF EIO GEANDE BASIN, 1888-1913. mento Mountains and reacliing to their crest. Throughout its upper course the Penasco is a perennial stream, but, owing to the porous soil of the Pecos VaUey, across which it flows after leaving the foothills of the Sacramento Mountains, the water sinks into the ground, leav- ing only flood water to reach the Pecos. The precipitation in the basin of the Penasco decreases from 23 inches and more at the crest of the Sacramento Mountains to 21 inches at Elk and 12 inches at the mouth. Most of the precipitation occurs during the summer months. GAGING STATION RECORDS. PENASCO RIVER AT ELK, N. MEX. Location. — At Elk post office, in sec. 5, T. 16 S., R. 16 E.

DELAWARE RIVER BASIN, GENERAL FEATURES. Delaware River rises in the northern part oi Culberson County, Tex., on the eastern slope of the Guadalupe Mountains, flows north- eastward, and joins the Pecos a few miles above the New Mexico- Texas Hne. The only important tributaries are the headwater streams forming the Delaware. The mean annual precipitation, as determined from the lines of equal rainfall (PL III) is about 13 inches for the area drained by the Delaware. On the headwaters, which rise at a considerably higher altitude, it is probable that the precipitation is somewhat greater. GAGING STATION RECORDS. DELAWARE RIVER NEAR MALAGA, N.

GENERAL FEATTJBES. Devils River rises in the western part of Sutton County, Tex., and takes a general southerly course to its junction with the Rio Grande at Devils River, in the southern part of Valverde County. It has no important branches. Except the Pecos, it is the most important tributary of the lower Rio Grande that enters from the Texas side, and in some years, owing to the extensive diversions from the Pecos and the lighter rainfall on the basin of that stream, it contributes more run-off. The area drained by Devils River hes on the southern extension of the Great Plains region known as the Edwards Plateau — a high mesa or table-land sloping gently upward toward the northwest — unforested except for scattered dense patches of scrub live oak, and covered with a thick growth of grass. The predominant rock of the area is a rough limestone, whose surface is level, as a rule, but is cut deeply by the few streams. Devils River flows in canyon for much of its course. Owing to the general flatness of the surface, drainage lines are few, and much of the run-off coUects in shaUow sinks so that the effective drainage area of the river is uncertain. Records of rainfall at points within and adjacent to the basm show the mean annual precipitation to be about 20 inches and to occur chiefly during the summer months. DEVILS RIVER BASIN. 699 GAGING STATION RECORDS. DEVILS RIVER AT DEVILS RIVER, TEX. Location. — Near the mouth of Devils River and opposite the station of the same nuine on the Southern Pacific Railroad. Records available. — May 1, 1900, to September 30, 1913. Drainage area. — Not measured. Gage. — Vertical staff. Channel. — Rocky and rough, with fissures and faults. Discharge measurements. — Made from car and cable. Floods. — The highest recorded flood occurred April 6, 1900, reaching a stage corre- sponding to 25.4 feet on the gage subsequently established. The next highest stage was 15.25 feet, the discharge being 52,400 second-feet. Accuracy. — Owing to the uncertain conditions of channel, very frequent discharge measurements are made, on which the estimates of daily discharge are based almost directly. Cooperation. — Station is maintained and records are furnished by the United States section of the International Water Commission.

Mimbres River drains an interior basin (see pp. 18-21) cliiefly in the northeastern part of Grant County, N. Mex. It rises on the west slope of the Mimbres Range, in T. 14 S., R. 10 W., and flows in a south- erly direction until its waters are lost in the desert plain in Luna County. It has no important surface tributaries, as the waters of Whitewater Draw, Lampbright Draw, and Cameron Creek are lost a short distance from its channel, but it is possible that they reach the Mimbres by seepage. The upper part of the basin, which furnishes a practically perennial flow to the Mimbres at least as far as the gaging station near Faywood, lies in mountainous country between the Continental Divide and the Mimbres Mountains, with elevations ranging from 5,000 to 8,000 feet above sea level. The lower part of the basin is a comparatively flat, gently sloping plain, in wliich elevations range from 4,200 to 5,000 feet above sea level and above which rise isolated mountains. In its course across this plain the river is intermittent for many miles before its waters finally disappear east of Deming. The lines of equal rainfall for the southwestern part of New Mexico (PI. Ill) indicate that the mean annual precipitation in the Mmbres basin decreases from 17 inches or more in the upper part to 10 inches in the vicinity of Deming. Although there are no records of rainfall in the mountainous part of the area, it is probable that the precipi- tation at the higher altitudes exceeds 17 inches. Little water is used for irrigation above the gaging station near Faywood, but below that point much of the flow is diverted. With- out storage, which has not yet been provided, the possibilities of irrigation from the Mimbres are small, as it is chiefly a floodwater stream. A good dam site located near the gaging station could be utilized to form a reservoir that would store sufficient water to reclaim several thousand acres of land along the river. GAGING STATION RECORDS. MIMBRES RIVER NEAR FAYWOOD, N. MEX. Location. — About 6 miles northeast of Faywood Hot Springs, in sec. 7, T. 20 S., R. 10 W., 10 miles from Faywood, a station on the Silver City branch of the Atchison, Topeka & Santa Fe Railway. Records available.— April 8, 1908, to September 30, 1913. Drainage area. — Approximately 450 square miles. Gage. — Automatic recording, installed August 13, 1909, at a point 200 feet upstream from the site of the chain gage originally installed. The chain-gage datum was lowered 4.00 feet on July 8, 1909, and the datum of the recording gage ia about 3.00 feet higher than the new datum of the chain gage. Channel. — Very shifting. 644 WATER RESOURCES OF RIO ORANDE BASIN, 1888-1913. Discharge measurements.^ — Made from car and cable during high water and by wading at other times. Winter flow. — Practically no backwater from ice at this point. Accuracy. — Owing to the meager data and shifting channel no estimates of discharge were made for 1911. The estimate for the other years are either approximate or fair, except for the last half of 1912 and for 1913, for which they may be considered good . Cooperation. — During 1912-13 station was maintained in cooperation with the State engineer. Discharge measurements of Mimbres River near Fayioood, N. Mex., in 1907-1913. Date. Hydrographer.

Cooperation. — Maintained in cooperation with the State engineer of New Mexico and the Chino Copper Co., Hurley, N. Mex. The following discharge measurement was made by E. L. Redding: August 15, 1913; gage height, 2.15 feet; discharge, 8.4 second-feet. Daily gage height, in feet, of Whitewater Draw at Hurley, N. Mex., for 1913. Day. July. Aug. Sept. Day. July. Aug. Sept.

CAMERON CREEK AT FORT BAYARD, N. MEX. Location. — Near the pumping plant at Fort Bayard, in sec. 25, T. 17 S., R. 13 W. 1 mile below the mouth of the nearest tributary, Beartooth Creek, an intermittent stream. Records available. — ^January 17, 1907, to September 11, 1911; August 6, 1912, to September 30, 1913. Drainage area. — Not measured. Gage. — Vertical staff for high stages and inclined staff for medium and low stages. Channel. — Shifting . Discharge measurements. — Made by wading. For the greater part of the year the flow comes from springs and amounts to less than 1 second-foot. Winter flo-w. — Ice does not appreciably affect the flow at this station. Diversions. — The intake for the Army post water supply is above the station, and a small amount of water is also diverted for garden irrigation. Accuracy. — Owing to the shifting character of the stream and a lack of high-water discharge measurements, estimates of flow are only approximate. Data 1911 to 1913 insufiicient for estimates of discharge. Cooperation. — Station maintained in cooperation with the United States Army and the State engineer.

MISCELLANEOUS MEASUREMENTS. 673 MISCELLANEOUS MEASUREMENTS. Discharge measurements have been made at many pouits in the Rio Grande drainage basin other than regular stations. These measurements have been compiled from the annual reports of the United States Geological Survey and arranged in accordance with the general rule for presenting discharge- data. The measurements on the Rio Grande itself are given first, begimiing with the measurement nearest the source and following the stream toward its mouth. Measurements on tributaries are arranged in the same order and follow those on the main stream. The measurements in this list do not inciude those made during the seepage investigations in 1911 and 1913. Miscellaneous measurements in Rio Grande drainage basin. Date.

In the arid regions, where water in large quantities is used for irrigation and where much of the soil and the underlying strata is porous, the surface tributaries of a stream do not furnish all the water in certain sections and diversions do not account for all the losses that occur in other sections. This unaccounted for gain or loss in flow is called seepage and represents the water that percolates through the ground either into or away from the river. The underground water reaching the river — which is called return seepage — may have entered the ground within a comparatively short distance of the point at which it reaches the river or many miles away and in an entirely different drainage basin. If, for example, water is diverted to irrigate porous soil in a valley the lower end of which is crossed by a dike, the dike may force the percolating irriga- tion water near enough to the surface to permit it to reenter the river; or, if there is no dike across the valley, the transverse slope of the valley toward the river may be so great that the percolating water is speedily returned to the stream. An example of return seepage occurring at a point remote from its origin is found where water per- colating through the ground enters a porous stratum which leads it finally to the river many miles away. This water may have been applied to the soil for irrigation or it may have been the natural percolation from rainfall. A thorough knowledge of the geologic formation of a drainage basin is necessary to determine whether return seepage is water originally diverted for irrigation in the upper part of a drainage basin or from natural ground water that may have originated in an entirely different basin. Nor is there any certainty that conditions of seepage remain constant throughout the year. Thus seepage investigations can show little more than the actual quantities gained or lost in different sections of a river at the time the measurements are made. It is highly desirable, however, that the investigation be made at a time during wliich the river and its tributaries remain at constant stage and chiefly for this reason such work is usually carried on in the fall of the year or early spring, when little water is being diverted and the flow is nearly constant. Thus results do not show the actual condition during the irrigation season when the river stage is changing, except by assuming that seepage conditions are fairly constant. Seven separate investigations to determine the gams and losses from seepage in the Rio Grande have been made at mtervals since 1900. Of these, five have covered a part of the river in Colorado, 680 WATER EESOUECES OF EIO GEANDE BASIN, 1888-1913. three the canyon section between the Colorado-New Mexico line and the gaging station at Embudo, two between Embudo and San Marcial, and one between San Marcial and El Paso. STUDIES ON THE RIO GRANDE IN COLORADO. THE MEASUREMENTS. The investigations covering the part of the Rio Grande in Colorado were made by the State engineer and the results, except for the measurements made in 1913, were pubUshed in the biennial reports. As the same measuring points were not used in the various series of measurements it is not possible to present the results in a compara- tive table. For that reason the results of each investigation are given separately, as originally published.

It is stated that frequent dupli- cate measurements showed no change in stage, so it is possible that the hydrographer kept ahead of the falling stage. SEEPAGE. 683 INTERPRETATION OF RESULTS. Tn order to study the effects of seepage, the river above the State Bridge at the entrance to the Rio Grande canyon, a few miles above the New Mexico line and a few miles from Lobatos, Colo., may be divided into three sections (1) the stretch above the Del Norte station, (2) that from the Del Norte gaging station to Monte Vista, and (3) that from Monte Vista to the State Bridge. Above the Del Norte gaging station little if any return irrigation water reaches the Rio Grande as most of the canals divert water below that point. Therefore any return water in all probability is natural undergi'ound flow from the mountains through which the river flows. The measurements made during the latter part of August 1900, show a gain from the South Fork to the Del Norte bridge of 48 second-feet, which is greater than for any other section during that investigation. On the other hand, the measurements made in 1903 showed little if any return seepage above the Del Norte station but a steadily increasing return below that point. The alluvial fan built up by the Rio Grande extends from the entrance of the river into the San Luis Valley (near the Del Norte gaging station) nearly to Monte Vista, as shown by Siebenthal in his report on the San Luis Valley.*^ Across this fan, as might be expected, occur the greatest seepage osses above the State Bridge, although the various investigations have shown that these losses ai-e not constant. During the measure- ments in 1907, for example, no losses appeared in this section. The greatest losses found were 26 second-feet in September, 1908, between Del Norte and the head of Prairie canal, and 31 second-feet between the same points in October, 1913. Measurements in August, 1900, showed a loss of 26 second-feet in a short stretch of river above Del Norte, at the upper edge of the, alluvial fan. From Monte Vista nearly to the State Bridge the Rio Grande flows across the San Luis Valley, the upper part of which is extensively irrigated. In this section the gains from seepage far outweigh any losses that may occm\ In general, the various series of measurements show an increase of return seepage, the total below Monte Vista being 32 second-feet during August, 1900, 23 second-feet in Septem- ber, 1903, 23 second-feet in September and October, 1908, and 13 second-feet in October, 1913. The 1907 measurements terminated at the mouth of the Conejos, but between that point and Monte Vista, the total return seepage was 67 second-feet. aJJ. S. Geol.

Three separate investigations of the seepage conditions of stretches of the Rio Grande in New Mexico have been made; one in March, 1911, from the State Bridge near Lobatos to San Marcial, another in October, 1913, from Lobatos to El Paso, and a third in October, 1913, from Lobatos to Embudo, at the lower end of the Rio Grande Canyon. The first was made by the United States Geological Survey, the second by the United States Geological Survey in cooperation with the State engineer of New Mexico, and the third by the State engineer of Colorado.

Mex., of 0.7 foot on March 11. This rise is thought to haye been caused mostly by Chama River, which enters the Rio Grande a short dis- SEEPAGE. 685 tance above, but a part was uiuloubtedly due to melting of snow and a rain which occurred in the region around Taos about March 7. This rise, however, preceded the measurements all the way down, and as the Buckman gage record shows the stage of the river to have been practically constant for the several days succeeding the rise during which measurements were made, it is thought that the condi- tion of the river was fairly even throughout the period. From the State line down to a point a few miles below Embudo the river flows through a box canyon which is cut in a lava forma- tion and ranges in depth from 50 feet at the State line to about 1,000 feet at Embudo. In this stretch the river in accessible at only a few places, as little water is contributed over the surface except by Rio Taos and Embudo Creek. The water flowing at the heads of several other streams sinks soon after it reaches the sheet of lava that borders the river on either side and enters the river as seepage. Between Embudo and Buckman the canyon widens out into a narrow valley in which some irrigation is carried on, and the river spreads out over a sandy bed and among islands. From Buckman the river flows in a comparatively narrow chaimel through White Rocks Canyon to Cochiti. At Cochiti the valley opens again into a flat sandy plain, and thence practically to San Marcial the river spreads out over a broad bed and among sand bars. Along this stretch considerable irrigation is practiced. At the Lobatos, the mouth of the Rio Hondo, San Juan, Buckman, Cochiti, and San Marcial, very good measurements of the Rio Grande were obtained. Conditions at the other measured sections were unfavorable and results are only fair. It should be noted that the river loses little, if any, water by diver- sion or otherwise above Embudo, and that below Embudo more or less water is being div^erted for irrigation; also, that in the lower stretch considerable loss from evaporation results from the spreading of the river over so much area and the openness of the valley. LOBATOS TO EL PASO. A special investigation of gams and losses in the Rio Grande from seepage between the State bridge near Lobatos, Colo., and El Paso, Tex., was made October 20 to 30, 1913, under the direction of Glenn A. Gray, district engineer in charge of the Santa Fe district. The stream was divided into four sections, a hydrographer being detailed to each section. The discharge was measured at various intervals along the main stream, at the mouth of each tributary, and at the headgate of each diversion. Automatic gages are maintained on the Rio Grande at the State bridge near Lobatos, Colo., at Embudo, N. Mex., Buckman, N. Mex., 686 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913. on the Cliama River at its mouth near Chamita, N. Mex., and on the Rio Puerco at its mouth. Staff gages, read twice daily, are main- tained on the Rio Grande at San Marcial, N. Mex., and El Paso, Tex., and on the Rio Hondo at its mouth. These gages showed the stream to be falling gradually during the last of October, with no floods to interfere with the investigation. From available maps, automatic gage records, and discharge meas- urements it was estimated that 10 days would be required for water to flow from the State bridge to El Paso, Tex. By the aid of the automatic gage charts, the estimated rate of flow, and the discharge measurements the entire seepage data were corrected to represent measurements of the same water passing different sections. These data represent natural conditions as they were found above Selden, N. Mex. Below this point the flow is controlled by the Leas- burg diversion dam, which irrigates a large area. It was found ex- tremely difficult to draw conclusions from observations below Elephant Butte, and in view of the fact that the Elephant Butte dam will soon control the flow to the New Mexico-Texas State line, more attention was given to that part of the stream above this point.

"While the Survey engineers were making measurements to deter- mine seepage between Lobatos, Colo., and El Paso, Tex., the State engineer of Colorado made an investigation from the State Bridge, near Lobatos, Colo., to Embudo, N. Mex. The following table has 688 WATER EESOUECES OF EIO GEANDE BASIN, 1888-1913. been compiled from data furnished through the courtesy of the State engineer: Seepage measurements on the Rio Grande from State Bridge, near Lobatos, Colo., to Emhudo, N.

To make the results of the various measurements directly com- parable, an allowance must be made for changes in the flow of Rio Grande, as determined in the first and third series of measurements. In the first investigation the flow was measured at the head of the box canyon 1^ miles below Questa and about 8 miles above the mouth, and as there are no intervening tributaries, the discharge at the mouth was assumed to be the same; in the second series of measurements, the discharge was determined both at the head of the canyon and at the mouth, and it was found that the flow increased in the canyon from 28.1 to 67.1 second-feet, a gain of 39 second-feet. Therefore it is evident that the discharge for Rio Grande, as determined in the first investigation, did not represent the entire flow entering the Rio Grande. It is impossible to state what the increase was in March, 1911, when the first seepage measurements were made, but as under- flow is much more constant than surface run-off, the results wiU be more nearly correct if the increase of 39 second-feet is apphed to the discharge of the Rio Colorado, making it 69 second-feet instead of 30 second-feet, as given originally. This \vill reduce the seepage gain between the Lobatos station and Dunn's bridge from 134 to 95 second- feet, and reduce all subsequent values in the last column by the same amount. In the third series of investigations tlie measurement was made 4 miles below Questa, and the results obtained were practically the same as those obtained in the second series at the head of the box canyon. Therefore it is evident that this discharge of 30 second-feet should be increased by 39 second-feet to show the flow of Rio Colorado at its mouth — especially as the second and third series were made SEEPAGE. * 689 within a few days of each other. Thus the flow of Rio Colorado entering the Rio Grande was 63 second-feet, and the seepage gain between Lobatos and Dunn's bridge 88 second-feet instead of 127 second-feet, as given in the preceding table. This change also reduces the total seepage gain at Embudo from 130 to 91 second-feet. A smaller increase, amounting to 4.3 second-feet, was found on Rio Taps between Los Cordovas and the mouth, but this correction, being relatively unimportant, has not been applied to the first and third series of measurements. To study in some detail the seepage conditions along the Rio Grande in New Mexico, the river may be divided into three sections: (1) Rio Grande canyon extending from the State Bridge near Lobatos, Colo., to Embudo, N. Mex.; (2) Espanola Valley and White Rocks Canyon, extending from Embudo to Pena Blanca, and (3) the section from Pena Blanca to El Paso. An attempt was made to compare by sections the results of the various seepage investigations but, except for the part of the Rio Grande canyon above Dunn's bridge, the results are so discrepant that the attempt was abandoned, and instead, the general effects of seepage in different parts of the river is discussed in connection with the measurements made in 1913. Except for a few small ditches below Glenwoody, there are no diversions for irrigation in the Rio Grande Canyon and, therefore, any return seepage does not come from near-by irrigation water diverted from the Rio Grande, as it probably does in San Luis Valley, but must come from a source more or less remote and may be either return irrigation water or natural underground water. The investi- gations in the upper part of this section all show a comparatively large return seepage. The measurements made in 1911 determined this to be 95 second-feet, whereas the two separate investigations in October, 1913, found it to amount to 140 and 88 second-feet, respec- tively. There is httle seepage in the lower section of the canyon. From Embudo to the mouth of the Chama near San Juan there was no return seepage and seepage losses amounted to 74 second-feet. These losses are accounted for by the porous soil over which the river flows in Espanola Valley. From the mouth of the Chama to the lower end of White Rocks canyon, near Pena Blanca, return seepage amounted to 104 second-feet, half of which occurred in the lower end of Espanola VaUey in the 4 miles between San Juan and Espanola. Measurements made in 1913 showed that practically no return seepage reached the river below White Rocks Canyon, and that seepage losses were large. From Pena Blanca to Bernalillo there was little seepage loss, in spite of the fact that tliis section is irri- 41823°— WSP 358—15 44 690 WATER EESOUECES OP RIO GRANDE BASUST, 1888-1913. gated extensively, and had been irrigated within a few weeks of the measurements. The absence of return seepage is probably due to the very porous soil in the river bed itself and to losses by evaporation of the water diverted for irrigation. This same condition is more marked in the lower part of the Albuquerque Valley and the Belen Valley in the section extending from Bernalillo to San Acacia near the mouth of the Arroyo Salado. The most rapid state of seepage loss in the New Mexico portion of the Rio Grande occurred between Bernahllo and Albuquerque, where, in a distance of 20 miles, the loss amounted to 100 second-feet, in a section extensively irrigated both during and prior to the investigation.^ Below Albuquerque the seepage loss is less, being practically nothing as far as Las Lunas, but from that point to the lower end of the Engle Reservoir site at Elephant Butte, the investigations showed seepage loss aggregating 254 second-feet in 130 miles. Between Elephant Butte and El Paso the seepage loss is much smaller — only 59 second-feet in 116 miles. STUDIES ON CHAMA HIVER. In addition to the seepage investigations on the Rio Grande itself, an investigation has been made of the seepage losses and gains in Chama River from Chama to its mouth. The gains and losses from seepage were investigated along Chama River from Chama, N. Mex., to the mouth of the stream by measuring the main stream, tributaries, and diversions at various points. The investigation was begun at Chama, N. Mex., October 28, 1 9 13 , by Frank O'Brien, junior engineer. United States Geological Survey, who car- ried the work to a point 46 miles south by river, or the mouth of the Gallinas River. From this point to the mouth of the Chama the work was done by John E. Powers, hydrographer for the State of New Mexico. Other investigations have been planned for the Chama River basin as it is beheved that stage of stream, preceding climatologic conditions and seasonal elements, are influential factors in regulating seepage in a basin. Automatic gages are being maintained on Chama River just above the confluence with the Rio Grande, El Vado, and Park View, and a staff gage is read twice daily at Chama. An automatic gage is also being maintained on Brazos River at the mouth of the Bos Canyon, so that the flow of the largest tributary of Chama River can be determined. During the period covered by this investigation the gages above El Vado showed some diurnal change caused by the melting snows. These changes in stage did not affect the flow at El Vado or that 1 It may be noted that during the measurements in March, 1911, return seepage amounting to 185 second feet was found in this section. The flood which occurred in the Chama during the latter measurement made the results below the mouth of that stream uncertain. SEEPAGE. 691 part of the stream below this point. The stage remained constant during the period from October 28 to November 3. Heavy rains aromid Abiquiii, Espanola, and north of Chamita caused the Chama, above the mouth of Ojo CaUente, to rise slightly, Ojo Caliente to carry 39 second-feet of water, and the lower Chama to rise about 1 foot. The data taken along the stream were corrected for time interval by means of the gages along the Chama and the velocities as obtained from the various discharge measurements. In this way it has been estimated that water that passed Chama the morning of October 29 reached the Rio Grande the morning of November 1. Chama River flows through a fertile valley from Choma to a point a short distance above the mouth of Nutritus Creek, where it boxes up and passes through a canyon to El Vado Valley. At the end of El Vado Valley, which is about 4 miles long, the stream passes through the Canyon de Chama, opening into Gallinas Valley. From Gallinas Valley it flows through a canyon above Abiquiu, whence it passes through a valley that joins the Espanola Valley of the Rio Grande. The topography along some sections of the Chama is so rough that it is exceedingly difficult to carry on an investigation of this kind. The following tables show the results of this work as compiled from the discharge measurements taken in the Chama basin on the main stream, tributaries, and irrigation ditches carrying water; also the record of daily gage heights taken from the various gages in the basin for the period of investigation : 692 WATER RESOURCES OF RIO GRANDE BASIN, 1888-1913.

It should be noted that 21 per cent of the flow is lost by seepage between Chama and Park View, and 42 per cent returns through seepage between Park View and the mouth of Nutritus Creek. In the canyon below the mouth of Nutritus Creek there is a gain of 17 per cent, in El Vado VaUey a loss of 31 per cent, in Canyon de Chama a gain of 13 per cent, in GaUinas VaUey a gain of 64 per cent, in Abiquiu Canyon neither gain nor loss, and in Abiquiu VaUey a loss of 29 per cent; the net result is a gain of 55 per cent between Chama and the mouth of the stream. EVAPORATION. THEORY OF EVAPORATION. The waters of the Rio Grande and its tributaries are already so fully utilized that any increase in development must come chiefly through storage of the flood waters. Whenever water is stored, and especially in a climate so hot and dry as that characterizing the greater part of the Rio Grande basin, it causes serious losses. The following brief discussion, based on "The general theory of evaporation" given in the Weather Bureau's Manual for Observers, is presented to show the factors that influence the rate of evapora- tion, in order that the magnitude of the phenomenon for any par- ticular locality may be better understood. From the surface of any sheet of water when the air rests upon it without motion, as in a calm, a series of vapor-pressure tubes extend upward, gradually spreading out into a sheaf like the magnetic lines surrounding the poles of a magnet. The vapor pressure at the water surface is a maximum, depending on the temperature of the water EVAPORATION . 695 surface. The pressure at any point in the tube varies inversely with its distance from the water surface and is a minimum at the dew point of the air. In other words, there is a vapor bhinket over the water surface caused by the particles of water passing from the water surface into the air. This blanket is densest at the water surface and becomes thinner as the distance above the water surface increases. The total depth or tliickness of the vapor blanket is determined by the relation between the vapor pressure at the water surface and the vapor pressure of the dew point of the air, Wlien these two are equal, there is little if any evaporation. When the difference between the two pressures is greatest (the pressure at the water surface being the greater) evaporation takes place at a maximum rate. When the vapor pressure of the air increases beyond the dew point there is a negative flow of vapor in the form of rain (or snow). From the foregoing it is evident that two very important factors influencing evaporation are the temperatures of the water and of the air. It may be noted that the drier the air the less its vapor pressure and, therefore, the greater the evaporation. Thus both temperature and humidity (or amount of moisture) of the air influence evaporation. Another most important factor is the velocity of the wind across the water surface. The wind blows away the densest portion of the vapor blanket that is in direct contact with the water surface, and in its place brings in drier air whose vapor pressure is much less. This greater difference in vapor pressure between the water surface and the air in contact with it immediately induces a greater rate of flow along the vapor tubes — just as the amount of water delivered by a pump against a pressure head is increased as soon as the pressure head is reduced. METHODS OF MEASUREMENT. The most direct way to determine evaporation is actually to measure the loss of water in a pan. The United States Weather Bureau, which carried on extensive experiments with evaporation pans placed in various surroundings, found that pans placed in the ground absorbed so much heat from the soil that the temperature of the water was greater than that in near-by ponds and reservoirs, and therefore the evaporation recorded was greater than simultaneous records from pans floating in the water; also, that pans placed at different heights above the water surface showed different results, depending on their relative positions in the vapor blanket. In problems involving storage the actual evapora- tion from the water surface should be determmed, and, as evaporation is very sensitive to atmospheric conditions within an inch or two of the water surface, the most desirable position in which to place the measurmg pan is to float it on the water itself. Unfortunately, in bodies of water exposed to high winds it is impossible to prevent the 696 WATER EESOUECES OP RIO GRANDE BASIN, 1888-1913. waves from slopping into the pan and vitiating the results, and there- fore it is usually necessary to select a relatively sheltered point in the pond or reservoir rather than one which is exposed to the effect of the average wind. The error introduced by this selection of location is within the limits of error allowable in solving hydrauhc problems dealing with storage and use of water. As more evaporation records are taken from ground pans than from floating pans, the following experiments are cited to show the errors that may be introduced by using the ground-pan records. At Hermiston, Oreg., and at Granite Reef, Ariz., the Weather Bureau found that evaporation from the pans set in the ground was greater than that from pans of the same size floating in water. The ground-pan record at Hermiston shows a total annual evaporation of 97.29 inches for the floating pan, 68.05 inches, or an excess of 43 per cent more than the water record. At Granite Reef the ground pan gave 115.18 inches and the floating pan 97.74 inches* an excess of 18 per cent. On the other hand, Prof. L. G. Carpenter, in his experiments at Fort Collins, Colo., found the temperature of the water in the ground pan to be less than that in near-by lakes and reservoirs, and increased his annual results from 46.3 inches to 59.5 inches, an increase of 28 per cent, to obtain the evaporation from reservoir surfaces. A like excess of floating-pan records over those for ground pans was found by Desmond Fitzgerald near Croton Reservoir, New York. It is evident from these experiments that records from pans set in the ground do not give the same results as floating pans, nor is it known definitely whether the ground-pan rates are too large or too small when applied to reservoir surfaces. Though the records from pans floating on the water surfaces are open to criticism, they approach much nearer true conditions for evaporation from large water surfaces than do the records from pans set in the ground. RECORDS OF EVAPORATION. So far as known, there are but three points in the Rio Grande drainage basin where evaporation records from pans floating in the water have been taken — at Fort Bliss near El Paso, Tex., at Lake Avalon near Carlsbad, N. Mex., and at Santa Fe, N. Mex. Records from pans set in the ground have been kept at several points. FORT BLISS. From 1889 to 1893 the United States Geological Survey kept an evaporation pan, 3 feet square and 10 inches deep, in the Rio Grande at Fort Bhss near El Paso. Owing to the difficulty of obtaining observations the results are fragmentary. The monthly summaries are given in the following table: EVAPORATION.

SANTA FE. Since May, 1913, records of evaporation have been obtained by the United States Geological Survey from a pan 3 feet square float- ing m an irrigation reservoir on Jones's ranch, three-fourths mile west of Santa Fe. The monthly summaries of evaporation are given in the followuig table: Evaporation, in inches, at Santa Fe, N. Mex., 1913-14. 1913.

The foregoing records are too brief to give conclusive evidence regarding evaporation in the Rio Grande Basin. It should be borne in mind, however, that the annual evaporation varies less than ram- fall or run-off, and therefore long-time records are not so essential. No records of evaporation from floating pans in the Colorado part of the basin, which includes the San Luis Valley, are available, but an approximate estimate can be made for San Luis Valley from the Santa Fe records. San Luis Valley is 600 to 1,000 feet higher than Santa Fe and is surrounded by mountains. The higher altitude tends to reduce the mean temperature and thus reduce evaporation. The effect of the lower temperature is at least partly offset by the greater altitude, which tends to increase evaporation by reducing atmospheric pressure. As these factors are more or less compensat- ing, it is believed that evaporation in the San Luis Valley will not differ greatly from that at Santa Fe. HECOEDS FROM PANS SET IN THE GROUND. Although records of evaporation as determined from pans set in the ground are Hable to large errors and must be used with caution, the following table showing the annual evaporation is presented to show the variation at different points and under different conditions : Evaporation from -pans set in the ground.
