Department of the Interior, United States Geological Survey, Hydrographic Branch, Washington, D. C, May 5, 1904. Sir: I have the honor to transmit herewith a manuscript by John C. Hoyt and Robert H. Anderson, relating to the hydrography of the Susquehanna River drainage basin, and recommend its publication in the series of Water-Supply and Irrigation Papers. In this paper has been brought together, in such form as to be of use to both the general and the engineering public, all the available hydrographic information in regard to this important area. It is intended that this paper shall be published in sequence with another (No. 108) entitled "Quality of Water in the Susquehanna River Drainage Basin, by Marshall Ora Leighton, with an Introduc- tory Chapter on Phj^siographic Features, by George Buell Hollister." The combination of the two papers will make available a large amount of valuable information with reference to the resources of this important river system. Very respectfully, F. H. Newell, Chief Engineer. Hon. Charles D. Walcott, Director United States Geological Survey. 7 HYDROGRAPHY OF THE SUSQUEHAMA RIYER BASIN, By John C. Hoyt and Robeet H. Anderson. IlS^TRODUCTIO?^. A detailed study of the hydrographic features of the Susquehanna River drainage basin has revealed the existence of a large amount of interesting data. These, however, are widely distributed in various publications and manuscripts which are in most cases inaccessible. This paper has been prepared to meet the constant demand for this information from both the general and the engineering public. The general deductions are intended to give the general reader a compre- hensive review of the principal conditions which exist in this area, while the base data have been given for the use of the engineer, so that he maj' make his own deductions and have sufficient data for estimates in hydraulic investigations. ACKNOWIiEDGME:N^TS. The records and reports of the United States Geological Survey have been the chief sources from which the data on flow have been obtained. These records have been carefully revised and in many cases recomputed. New rating tables based on all the discharge measurements to date have been prepared and the tables of estimated discharge have been revised to agree with these rating tables. These recomputations will account for the differences between the figures herein presented and many of those in the previous reports, as the latter were prepared from year to year with such information as was available. Special acknowledgment is due to E. G. Paul, resident hydrographer for Pennsylvania, who established the gaging stations and under whose direction the discharge measurements in this State have been made. The stations in New York were established and have been maintained under the direction of R. E. Horton, resident hydrographer for that State. The base data from which the precipitation tables have been pre- pared were taken from the published reports of the United States Weather Bureau. lO HYDEOGKAPHY OF SUSQUEHANNA BASIN. [no. 109. The tables showing the utilized horsepower in 1900 are from manu- script schedules furnished by the manufactures division of the Twelfth Census. In the preparation of descriptive portions of the paper Vol. XVI of the reports of the Tenth Census (Water Powers, Part I), Rogers's Geology of Pennsylvania, and the Army Engineers' reports have been largel}^ drawn upon. The annual reports and original records of the Chief of Engineers, United States Army, have furnished valuable information in regard to declivity, and the profiles herewith given are largely based upon them. The data for McCalls Ferry have been furnished through the kind- ness of Dr. Gary T. Hutchinson, of New York City, who is interested in the power development at that point and had charge of extensive surveys and studies there in 1902 and 1903. Special mention is due Boyd Ehle and R. H. Anderson, who established and carried on the measurements at the McCalls Ferry gaging station. Acknowledgment is also due to Frank H. Brundage, H. J. Saunders, L. R. Stockman, and other members of the hydro-computing section of the United States Geological Survej^ for assistance given in the computations and in other work connected with the preparation of the many tables. DESCRIPTIOIS^ OF DRAINAGE AREA. ■ GENERAL FEATURES. The Susquehanna River basin is the largest and most important drainage area commercially in the^North Atlantic States, although it is not the most important as regards water power, The headwaters of this river system are on the elevated plateau which separates the waters which flow south and east into the Atlantic streams from those flowing north and west into the Mississippi, St. Lawrence, and Great Lakes. Geologically, this watershed lies in four physiographic divisions: the Allegheny Plateau, the Allegheny Mountains, the Great Allegheny Valley, and the Piedmont Plateau. Its distribution among these provinces is approximately as follows: Allegheny Plateau, 56 per cent; Allegheny Mountains, 31 per cent; Great Allegheny Valley, 6 per cent; Piedmont Plateau, 7 per cent. As the physical features of the foregoing divisions and the early history of the formation of this basin, as well as the qualitj^ of the water, have been fully discussed by Messrs. G. B. Hollister and M. O. Leighton in Water-Supply Paper No. 108, further discussion here is omitted. The Susquehanna drainage basin, as shown in fig. 1, has a total area of 27,400 square miles. It comprises 21,060 square miles in Pennsyl- vania, or about 47 per cent of the area of the State; 6,080 square miles in New York, or 13 per cent of the area of the State; 260 square miles in Maryland, or about 2 per cent of the area of the State.

BED OF SUSQUEHANNA RIVER AT McCALLS FERRY CABLE STATION, DURING LOW WATER. fNDEKSON.] DESCRIPTION OF DRAINAGE AREA. 19 SUSQUEHANNA RIVER BELOW WEST BRANCH. STisquehanna River is joined by the West Brancli at Sun bury, Nortbumberland County. Below this point the river drains an area of 9,230 square miles. It flows nearly south, between Northumberland, Dauphin, and Lancaster counties on the east and Snyder, Juniata, Perry, Cumberland, and York counties on the west, passing then into Maryland, where it flows between Cecil County on the east and Har- ford County on the west, and empties into Chesapeake Bay at its northern extremity. Below the mouth of the West Brancli the fall becomes more irregu- lar than above, and there are rapids where the stream flows over a rocky bottom. In the lower part of its course from Marietta to Havre de Grace the river occupies a deep valley, varying in width from a few hundred yards to more than 2 miles, and on either shore it is for the most part bounded by rocky bluffs surmounted by a table- land 100 to 500 feet above the stream. The channel is in many places filled with small rocky islands, some of which are cultivated. Pis. I, J5, and YIII show typical views of this part of the river. The fall of the main river is rapid. Its elevation at the mouth of the West Branch is about 400 feet above mean sea level at Havre de Grace. The distance between this point and Havre de Grace is about 125 miles, hence the mean slope of the main river is nearly 3^ feet per mile. The slope is, however, extremely variable, being over 5 feet per mile in the lower 40 miles and about 2| feet per mile in the upper 40 miles. The change in slope takes place as the river passes from the Allegheny Mountain and the AUeghenj^ Valley regions to the Piedmont Plateau region. The tables on pages 207-210 give the elevation of the river and its branches at various points, and Pis. XXVIII and XXIX show their profiles. This part of the river is described by Prof. H. D. Rogers as follows:'* Between Northiimberland and the Kittatinny Valley the river leads its through many striking scenes. It is studded with many little islands, most of which are covered with trees or bushes to the water's edge, and it is here a wide and majestic river, flowing alternately for long reaches across highly cultivated belts of coun- try and past the ends of steep and rugged mountains. Passing out from the mountains it traverses a beautiful country in the Kittatinny Valley, dividing Dauphin from Cumberland County. Quitting the limestone valley the river next traverses the red-shale belt, between the villages of Highspire and Bain- bridge, crossing a rather monotonous country, except at the Conewago Falls, or rapids, where numerous hard trap dikes impede its course and cause it to rush in wild tumult, by deep and dangerous sluices, for a long distance between black and jutting reefs. At Chickies Ridge, 1 mile above Columbia, the river leaves the smoother country and passes between a range of high and picturesque crags. "With two or three intermissions, caused by the softer limestone valleys which it next crosses, it runs the whole way thence to the vicinity of Port Deposit, or nearly to the Chesapeake Bay, between steep naked and half naked hillsides, rising <« (reol, Pennsylvania, p. 49. 20 HYDROGRAPHY OF SUSQUEHANNA BASIN. [no. 109. from 300 to 400 feet above its channel. In some parts of this long reach, as at Washington Borough, the river is greatly dilated and is filled with rocky islands and projecting reefs. In other localities its rugged banks approa jh. and the river rushes with tremendous force, especially during freshets, through these deeper gorges. The traveler, who finds only a rough and very toilsome path along its eastern shore from Turkey Hill to Port Deposit, a distance of more than 30 miles, will choose to descend it by its right bank along the towpath of the canal. He will pass an almost unbroken succession of interesting rocky scenes, affording much geological instruction, and he will witness many beautiful bits of river per- spective, but he will find himself pent in all the way between the bold river hills. The principal tributary below the West Branch is the Juniata, which has its source in Bedford, Blair, and Somerset counties. Pa., at an ele- vation of about 2,000 feet above sea level. The divide between its waters and those of the Ohio attains in places a height of nearly 2,800 feet. The valley of the stream is narrow and the banks are generally high. The stream has a number of both large and small tributaries. Doctor Rogers describes the -Juniata as follows : "- This second great tributary of the Susquehanna has two chief upper divisions, the Frankstown and the Raystown branches, both of which, like the main stream below their junction, traverse much beautiful scenery. We will trace the Franks- town Branch as that which is most accessible. After gathering its headwaters from the eastern slope and the foothills of the Allegheny Mountains it begins to assiTine the volume of a small river near Frankstown. Below this point it first passes the cove of the Lock Mountain, a curious district of conical hills, in struc- ture like the Muncy Hills of the West Branch. Its course is now by a wild and rocky gorge through the Lock or Canoe Mountain into Canoe Valley. Winding northeastward through this valley it next goes through Tusey Mountain into Hartslog Valley by an interesting curving pass of the form of the letter S. The mountain, which consists of two ridgesi^,4s trenched along its center for the pas- sage of the river, and the western ridge iSu moreover, breached at Water street by a lateral not3h, which gives passage to a small tributary stream and heightens much the pisturesqueness of the place, which is further enhanced by a great stone slide covering the ends of the mountain. Crossing Hartslog Valley it next trav- erses Warrior Ridge, passing by the Pulpit Rocks. Emerging from the Warrior Ridge and deflecting more toward the east it crosses the Huntingdon Valley and passes by the northern end or knob of Terrace Mountain or Slideling Hill , receiv- ing first the Raystown Branch, which nearly doubles the volume of its waters. Here, bending southward, it follows a picturesque gap through Stoi:e Ridge, and turning more eastward it presently enters the deep cleft in Jacks Mountain called " Jacks Narrows,"' upon the western side of which the mountain is covered with a great stone slide or field of naked angular blocks of sandstone, which imparts a most desolate aspect to the pass, especially when the forest is not in leaf. On emerging from Jacks Narrows the river crosses a succession of open valleys divided by narrow ridges until it meets the base of Blue Ridge in Sugar Valley. There it makes a great loop, turning in an oxbow backward till it reaches Newton Hamilton, where it flows with many large sinuosities longitudinally through the Juniata or Lewistown Valley to the deep synclinal ravine called the ' ' Long Nar- rows," formed by the near approach of the Blue and Shade mountains. The Long Narrows of the Juniata is a narrow trough between mountain ridges, deeply trenched on their flanks and thickly clothed with timber on their lower slopes and a Geol. Pennsylvania, p. 50. HOYT AND ANDEKSOX f] DESCRIPTION OF DRAINAGE AREA. 21 at their base, and overspread nearer their snnimits with extensive sloping sheets of dark-gray angular blocks. The pass is 7 miles long and is one of the wildest and most impressive within the mountains. At the eastern end of the Long Narrows the river tvirns southeastward and winds between hills and valleys across the country to the base of the Tiiscarora Mountain, passing Mifflintown, Mexico, and other villages. Below New Mexico it sweeps the base of the Tuscaroi-a Mountain for several miles, until it turns abruptly across its eastern end a mile northwest of Millerstown. Below Millerstown the river crosses the Wildcat and Buffalo val- leys, washing the end of the Buffalo Mountain. Pursuing its course, the Juniata, after making two or three bends, flows through a belt of hills called the " Half- Fall Mountain," where, as at nearly all its passes through the larger sandstone ridges, it is impeded by ledges of hard strata and thrown into ripples or rapids. From the Half-Fall Rapids it flows between steep but low cliffs and hills for about 4 miles farther, to its entrance into the main Susquehanna at Duncans Island, having followed a winding course entirely across the central zone of the Appa- lachian chain through a distance of nearly 200 miles. SUSQUEHANNA RIVER ABOVE WEST BRANCH. This portion of the stream and its tributaries drain an area of about 11,140 square miles, of which 6,080 are in New York and 5,060 in Pennsylvania. It rises in Otsego Lake, in Otsego County, N. Y., which is about 7^ miles long and 1^ miles wide, and has an elevation of about 1,193 feet above sea level. It flows in a south- westerly direction through Otsego, Chenango, and Broome counties, N. Y., into Susquehanna County, Pa. It then flows in a westerl}^- northwesterly direction through this county and again enters New York and takes a westerly course through Broome and Tioga coun- ties to near the western boundary of Tioga County, where it turns south and enters Pennsylvania. Before leaving New York its volume is rapidly swelled by many large tributaries. After entering Pennsyl- vania the second time it flows through Bradford, Wj^oming, Luzerne, Columbia, Montour, and Northumberland counties to its junction with the West Branch, above Sunbury. This portion of the drainage basin is varied in character. In New York it is a rolling and sometimes rather broken country, forming the plateau bounding the mountain region on the north. The stream has a very uniform declivity in this part of its course and offers compara- tively little power. Its bed is gravel or sand, with an occasional rocky ledge. Its banks are moderately high, shelving, and are sub- ject to overflow only in extreme freshets. After it enters Pennsylvania it flows through the mountain regions, and its course is in many places tortuous as it winds along the paral- lel ranges of hills. In general, however, its fall is gradual, its bed being composed mostly of drift materials — gravel, sand, and bowl- ders. The banks, as in New York, are generally high and are seldom overflowed, although the river has an extreme rise of as much as 30 feet. In this portion of the drainage area is located the great Lackawanna and Wyoming coal basin, and J. H. Dager reported upon this, in sub- ^2 HYDROGRAPHY OF SlTSQtJEHANlSrA BASIN. Ixo. 109. stance, as follows: "• This basin extends from Nanticoke on the sonth- west, where the river emerges from the Coal Measures, to Carbondale on the northeast. It is about 50 miles in length and averages o^ miles in width. It is surrounded by the Allegheny Mountains, which are composed of the Catskill formation and rocks of the Carboniferous system. In this vicinity there are several workable seams of coal, ranging from 3 to 14 feet in thickness and at depths varying from nothing to 800 feet. These seams are from 10 to 200 feet apart vertically, and are underlain by sandstone and fire clay. From the outcrop of the Coal Measures just above Pittston to the New York State line the country is traversed by long, narrow, parallel ranges of mountains whose axes are nearly at right angles to the gen- eral direction of the river. At bends on the convex side there rise from the shore abrupt cliffs from 200 to 400 feet in height, opposite which, with one or two exceptions, are gently sloping cultivated lands. Professor Rogers refers to this portion of the river as follows : * That portion of the Susquehanna River which flows near the northern boundary of the State passes from its sharp elbow, called the " Great Bend," to the mouth of its affluent, the Chemun;^ River, through a charming, broad valley, bounded by soft slopes terminating in wide, table-shaped hills. It is a fertile and very beautiful district, and with its westward extension, the plain of the Chemung River, is rapidly becoming one of the most attractive agricultural districts of New York. From the mouth of the Chemung River to Pittston, where the river suddenly tvirns at a right angle on entering the Wyoming coal field, it flows, with many bendings, along a deep and picturesque valley, almost identical in its fea- tures with that o" the corresponding st,retch of the Delaware, the main difference being that the bed of the valley is wider^and the hillsides confining it less moun- tainous. From the mouth of the Lackawanna, at Pittston, where it enters, to Nanticoke, where it leaves the beautiful Wyoming Valley, the scenery along the river is wholly different. It flows through a broad and almost perfectly level, smooth plain — the Wyoming and Kingston flats — composed of a deep bed of dilu- vium or drift. On either side of this plain rise the rolling hills of the coal basin, and behind these the long, gentle slopes of the high mountain barriers, which frame in the whole scene. At Nanticoke the river turns abruptly northward out of the coal basin, through its steep barrier, by a highly pictiiresque pass, and then sweeps again as suddenly westward to run for several miles in a closely confined trench batween the outer and the inner ridges of the basin. It does not, however, run round the western end of this, but at the ravine of the Shickshinny turns suddenly southward and cuts across its point, leaving a high, isolated hill of the coal strata on its western or right-hand side. Disengaging itself by a fine pass from the southern barrier of the coal basin, it passes out into an open valley and makes another rectangular bend, to run once more toward the west, parallel with the Nescopeck Mountain, which it follows to the neighborhood of Catawissa. Beyond this point it maintains its general course westward, somewhat south, parallel with the southern base of Montour Ridge, all the way to Northumber- land, where it is joined by its great tributary, the West Branch. In some portions of this long reach of the river the scenery adjoining it is uncommonly rich and pleasing. A remarkably fine view up the river is presented from the hills on its west bank, a little below the mouth of Fishing Creek. a Ann. Rept. Chief of Engineers, U. S. Army, 1884, pt. 1, p. 873. cGeol. Pennsylvania, p. 48. Anderson.] DESCRIPTION OF DRAINAGE AREA. 23 WEST BRANCH OP SUSQUEHANNA RIVER. The drainage basin of the West Branch has an area of approxi- mately 7,030 square miles, all of which is in Pennsylvania. The West Branch has its sources in the mountains of Cambria County at an elevation of not less than 2,000 feet above sea level. It flows first in a northward direction, receiving some tributaries from Indiana County on the west, into Clearfield County. Gradually bending to the right, it flows northeast between Center and Clinton countieSj east through Clinton and Lycoming counties, and south between Union and Northumberland to join the main stream above Sun- bury, Pa. The watershed of this stream occupies the high table-lands of the north-central part of Pennsylvania. The crest of the watershed has an elevation of from 500 to 1,200 feet above sea level in the vicin- ity. of the junction of the West Branch and the main stream, in- creasing to about 2,200 feet at its southwestern part; thence along its western side it maintains this latter elevation to its northern line, where, in the northern part of the Pine Creek basin, it attains an elevation of over 2,600 feet. Along the remainder of the northern crest the height quickly falls to about 1,200 feet, but rises again to about 2,000 feet along the eastern crest of the divide. The highest points in the State are along the crest of this watershed. As far up as Queens Run the fall of this branch is comparatively small, while above that point, in the mountain region, it is much greater. Furthermore, the banks of both the stream and its tribu- taries above Queens Run are generally high, and there are few low grounds subject to overflow. Below Queens Run the river traverses a wide, fertile valley, without, however, overflowing its banks to any considerable extent. The bed of the river is generally gravel and sand, with a rocky ledge at places. In former years this portion of the drainage was largely used by lumbermen for floating logs. On most of the streams splash dams were built, sometimes flooding con- siderable areas, and serving to hold the logs which were sent down until a sufficient number were collected. The gates in the dam were then raised, letting the water out suddenly, so that the logs were car- ried down on the swell or wave to the next dam or to the main river, where the natural current would be sufficient to carry them along. As the forest areas are now largely cut off, but very little logging is done either on this or other portions of the river. Professor Rogers describes this branch of the river as follows : ^ The tipper part of the West Branch of the Susquehanna, and also its tributa- ries, the Sinnemahoning, Kettle Creek, Pine Creek, etc., draining the high plateau northwest of the Allegheny Mountains, flow through deep trenches in the hori- zontal strata, very analogous in their features to those which give passage to the Delaware and the Main or North Susquehanna, in the northeastern part of the State. Prom the mouth of the Sinnemahoning out into the Bald Eagle Valley, aGeol. Pennsylvania, p 49. 24 HYDEOGUAPHY OF SUSQUEHANNA BASIN. [no. 100. the river hills are very high and steep, and admit extremely narrow strips of ground betvpeen their feet and the river, except near the oj^enings of the lateral streams. The trough through which the lower half of Pine Creek flows is equally profound. Entering the valley between the Allegheny Mountains and the Bald Eagle ridge, the river pursues a beautiful winding course the whole way from Lockhaven to the neighborhood of Muncy, alternately sweeping toward the middle of the cultivated valley and back again, close in to the base of the steep and wood-covered ridge. Near Muncy it turns with a broad majestic curve round the end of the Bald Eagle Mountains, and in a few miles deflects from a southwest to a west course, throtigh a highly fertile, richly cultivated open country, till it strikes the base of the Blue Hill, or range of red sandstone cliffs above Northumberland. Southwest of Muncy the river crosses a singular belt of deeply eroded country, full of conical hills. NAVIGATION. Information in regard to navigation along Susquehanna River and its tributaries is now only of historical interest. The official records of Pennsylvania and other papers published during the early part of the century show that from the first settlement Susquehanna River and its tributaries were regarded as a possible means of navigation. In this relation the following quotation from Dager's report is of interest : ^ General Sullivan, to punish the Six Nations, late in August, 1779, organized a force of 3,000 men and moved north from Wyoming, the artillery and stores being drawn up the North Branch in 150 boats. At Tioga he was joined by Gen- eral Clinton with 1,000 New York troops. The latter had marched from Albany to Otsego Lake, where, flnding the water too low to flo t his bateaux, he built a dam across the stream, by which the lake was raised several feet, and when the dam was cut away the discharge wavQfloated his boats down to Tioga. The Indians fled in dismay at the sigl^t of a flood in the midst of the summer drought, believing it a signal of the dis|pleasure of the Great Spirit. From this might be inferred that Otsego Lake could be made a reservoir to pay tribute to the river when there was an insufficient flow. On March 9, 1777, an act was passed declaring Susquehanna River a public highway as far down as Wrights Ferry, and later on, March 31, 1785, the whole river through Pennsjdvania was declared a public highway. An appropriation of £6,290 was made as early as April 11, 1791, for the improvement of the navigation of Susquehanna River. Other appropriations were made from time to time and active canals were maintained from Havre de Grace to the New York State line, on the West Branch from Northumberland to Lock Haven, and on the Juniata from Juniata Junction to Holidaysburg. Between 1800 and 1830 several plans were proposed for connecting Susquehanna River with the Great Lakes and Avith Mississippi River. Nothing, however, came of any of these projects, and with the com- ing of the railroads the canals were gradually abandoned, being in most cases bought by the railroad companies. The North Branch extension, from the New York State line to Pittston, was abandoned in 1868 or 1869. The canal from Pittston down was used more or less « Ann. Eept. Chief of Engineers, U. S Army. 1884, pt. 1, p. 876. HOYT AND ANDERSON. MEASUREMENTS OF FLOW. 25 until the fall of 1874, but the high floods of the spring of 1875 caused so much damage that no boats were ran after that date above Wilkes- barre. The Lackawanna Canal served as a feeder for the Wilkes- barre Branch until the spring of 1882, when it was abandoned to the Nanticoke dam. The canals below Sunbury were abandoned about 1890. MEASUEEMEIVTS OF FEOW. The records of the measurements of flow in the Susquehanna drain- age have been divided into two classes : First, those at regular sta- tions, where systematic observations have been carried on over a series of years; second, those at miscellaneous stations, which consist of short or broken series of observations. There have been nine reg- ular stations maintained, as given in the following list: Gaging stations in the Susquehanna drainage basin. ' Stream. Location. Date established.

The bench mark is a chiseled draft on the corner of the left abutment on the upstream side. Its elevation 2() HYJDROGKAPHY OF BUSQUEHANNA BASIN. [no. 109. is 23.71 feet above gage datum. This bridge is located about 800 feet upstream from the junction of Chenango and Susquelianna rivers. A rift extends diagonally across the stream underneath the bridge. The gage is above a stretch of smooth water extending from the crest of the rift to the dam 2,800 feet upstream, and the gage readings are not affected by backwater from Chenango River at ordinarj^ stages. On account of unfavorable conditions of Washington Street Bridge discharge measurements are made at Exchange Street Bridge, which is 1,900 feet upstream.

[no. 109, CHENANGO RIVER AT BINGHAMTON, N. Y. This station was established by R. E. Horton July 31, 1901. The gage is located on the upstream side of the first span from the right bank of Court Street Bridge, Binghamton. It is a boxed wire gage secured to the vertical supports of the hand railing. The bench mark is a circular chisel draft on the upstream corner of the bridge seat on the left abutment. Its elevation is 84.02 feet above gage datum. Court Street Bridge stands squarely across the stream, which has a nearly horizontal bed of gravel and small cobblestones, affording a smooth, uniform current for gaging. The channel is obstructed by three masonry piers supporting the four spans of the bridge, 79 feet clear width each, the bridge having a total length of 337 feet between abutments. The bridge is situated 2,500 feet above the confluence of Chenango and Susquehanna rivers. A small rift below the bridge cuts off backwater from the Susquehanna at ordinary stages of the rivers. For periods during freshets or at times when there is an abnormal rise on one stream, accompanied by a similar rise in the other stream, either the Chenango or Susquehanna River record at Binghamton may be affected by backwater, indicating a too great discharge. For freshets of considerable duration the flow of the two streams will be more nearly equalized. Gage readings on Chenango River, as well as those on Susquehanna River at Binghamton, are taken by E. F. Weeks. In estimating run-off of Chenango River the area directly tributary to storage reservoirs from which diversion is made to supply Erie Canal has \been deducted from the total area naturally tributary to Chenango River. In estimating the run-off of Chenango River the area directly tribu- tary to storage reservoirs, from which diversion is made to supply Erie Canal, has been deducted from the total area naturally tributary to Chenango River, as follows: Square miles. Nattiral tributary area « , 1, 580 Diversion area, 6 reservoirs at head of Chenango River, whose overflow is turned into Erie Canal through Oriskany Creek 30 Diversion area, De Ruyter reservoir, at head of Tioughnioga River; out- flow turned into Erie Canal through Limestone Creek 18 48 Net area used for Chenango basin 1, 532 Above estimate of diversion area is approximate. No allowance for direct inflow to feeder channels from additional areas nor fo.' waste into original stream. Gross area, from which more or less run- off is diverted, is about 105 square miles. a From Bien's Atlas of New York State. Areas tributary to reservoirs are from New Yort- Barge Canal Report, 1900.

The Wilkesbarre station was established by E. G. Paul ou March 30, 1899. The standard chain gage is located on the upstream side of the Market Street Bi'idge. The length of the chain from the end of the weight to the marker is 40.83 feet. The gage is read once each da}^ b}^ W. S. Bennett, the bridge keeper. When this gage was estab- lished, there was found to be a gage ]3ainted on the bridge pier, being a portion of one established by the AVeather Bureau. The lower part of this gage, erected in Januarj^ 1898, originally consisted of heavy cast-brass plates graduated to feet and tenths. The gage plates were made in i-foot sections and bolted to the stone bridge pier. The two lower sections of the brass plates had been torn away by ice, so that there was no graduation below the 8-foot mark, but readings were made by the figures painted on the stone pier. The zero of this old gage is at the base of the dressed-stone portion of the pier and is reported to be 535 feet above sea level. During low stages of the river the water recedes from the pier, rendering it impracticable to read the gage. So far as could be ascertained, this 44 HYDKOGRAPHY OF SUSQUEHANNA BASIN. [no. 109. has not been connected with the citj^ datnm. On account of tlie low water, which in 1897 liad gone below the city datum, it was decided to put the zero of the new gage 4 feet below the zero of the old Weather Bureau gage, so as to obviate minus readings. In order, therefore, to compare with former records, it is necessary to add 4 feet to the old figures. The danger mark of this Weather Bureau gage is at 14 feet, or 18 feet of new gage, as at this elevation the west bank of the river is under water in places. River reports from this localit}^ were furnished as early as 1888. During low water measurements were made by wading at a better cross section, at Retreat, 10 miles below Wilkesbarre. The elevation of the Market Street toll bridge above the river bed requires 65 feet of cable to sound across the section. Observations of fluctuations of Susquehanna River are made by the Weather Bureau above Wilkesbarre, at Towanda, Pa., where the drainage area is estimated to be 8,000 square miles. The river gage, made of iron 1 foot wide and one-half inch thick, is on the east side of the road bridge over Susquehanna River, and is securelj^ bolted to the masonry of the pier. The graduation is from to 25 feet. The highest water was 29 feet in March, 1869, and the lowest, —0.1 foot, in October, 1895. The danger line is at 16 feet. The elevation of the zero is 633.7 feet. Discharge measurements are made from the downstream side of the bridge, which has a total span of 700 feet between abutments. The initial point for soundings is the end of the iron handrail on the left bank, downstream side. The ch^nel is straight for about one-fourth mile above and below the station.^ There is a bar across the river about one-half mile above the station, and another at about the same distance below, with deep water between these two points. This makes a sluggish current at low stages. The right bank is low and overHows at a gage height of about 20 feet. The left bank is above ordinary floods. The bed of the stream is composed of sand and gravel and is somewhat shifting. There is but one channel, broken by 3 bridge piers. There are a few willows growing under the right span. The bench mark is the extreme west end of the stone doorsill of the north entrance to the Coal Exchange Building. Its elevation is 32.99 feet above uase datum.

Paul.- It is located at the Mill Street Bridge, 600 feet south of the public square, Danville, Pa., near the Pennsj^lvauia Railroad sta- tion at South Danville. The box of the standard chain gage is bolted to the hand rail on the lower side of the bridge 200 feet from the right bank. The length from the end of the weight to the marker is 42.85 feet. The gage is read once each day by E. F. Bell. Discharge meas- urements were made from the lower side of the Mill street covered wooden highway bridge. This bridge was carried away by the ice on March 9, 1904. From that time until the water dropped below gage height, 5 feet, its stage was observed on the Weather Bureau gage. After the water fell below 5 feet its stage was measured approxi- mately, until September 30, 1904, by means of temporary gages set by the gage reader. This bridge had a total span of about 1,300 feet. The initial point for soundings was at the end of the wooden hand rail on the left bank, downstream side. The channel is straight for about one-half mile above and below the station. The right bank is low and liable to overflow. The left bank is high and is not subject to over- flow~ The bed of the stream is rocky, with some gravel, and is per- manent. There is but one channel, broken by the six bridge piers, which do not obstruct the flow to any considerable extent. The cur- rent is moderately rapid, except at very low stages, when it becomes sluggish. The bench mark is the extreme south end of the stone doorsill at the east entrance to the city filter plant. Its elevation is 31.7 feet above gage datum. HOYT ANDERSO ^^°] FLOW OF SUSQUEHANNA AT DANVILLE, PA. 57 Discharge measurements of Susquehanna River at Danville, Pa., 1899-1903.

HOYT AND ANDEESO ID "I N.J MEASUREMENTS OF FLOW. 67 WEST BRANCH OF SUSQUEHANNA RIVER AT M'lLLIAMSPORT, PA. This station was established March 1, 1895, by George D. Snyder, who was at that time city engineer. On August 16, 1901, a standard chain gage was installed on the uxjper side of the Market Street Bridge. It is i-ead once each day by Henry H. Guise, who is employed in the city engineer's office. The length of the chain from the end of the weight to the marker is 40.29 feet. Discharge measurements are made from the lower side of the Market street iron highway bridge. The initial point for soundings is the face of the abutment on the left bank. The channel is straight for several hundred feet above and below the station, is broken by four bridge piers, and is about 1,000 feet wide at the station. There is a dam about one-half mile above the station. Both banks are high and rocky. The bed of the stream is composed of gravel and silt, and will probably change to some extent in the shore spans. The current velocity is sufficient for accurate measure- ment, except at extreme low stages. The bench mark is a cut in the face of the left abutment 10,07 feet above gage datum.

ANDEKSON.] MEASUBEMENTS OF FLOW. 93 JUNIATA RIVER AT NEWPORT, PA. Juniata River rises in Center County, Pa., and flows in a general southeasterly direction into Susquehanna River 15 miles above Har- risburg. Its drainage area is mountainous and for the most part covered with forest growth. This station was established at Newport, about 15 miles above the mouth of Juniata River, March 21, 1899, by E. G. Paul. The standard boxed chain gage was located on the covered wagon bridge which was 800 feet east of the public square at Newport, Pa. It was attached to the bridge timbers inside of the bridge near the right bank. The length of the chain from the end of the weight to the marker was 39.54 feet. The gage is read once each day by A. R. Bortel. Bench mark No. 1 is on the extreme east end of the stone doorsill, south front of Butz's store building, near end of bridge; its elevation is 28.83 feet above gage datum. Bench mark No. 2 is on shelf in southeast corner of underpinning of store of J. M. Ewing; its elevation is 27.37 feet above gage datum. This bench mark was set by the Pennsylvania Railroad, and according to their records its elevation is 390.69 feet above sea level. Discharge measurements were made from the lower side of the four-span wagon bridge to which the gage was attached. The initial point for soundings was the end of the woodwork of the bridge on the right bank downstream side. In the fall of 1904 this bridge was replaced by a steel structure. -During its construction the stage of the river was obtained by means of a temporary gage staff attached to the exposed end of a sewer near the bridge. This gage was set at the same elevation as the old one. As soon as the bridge is completed a standard chain gage will be put in place. The chan- nel is straight for one-half mile above and below the station. Both banks are high and are not subject to overflow. There is a single channel, broken by three bridge piers. The piers do not interfere with the flow of the stream and there is little eddying and boiling near them. The bed is of hard material and is probably permanent. There is a good measurable velocity at all stages. 94 HYDROGRAPHY OF SUSQUEHANNA BASIN. L-w. 109. Discharge measurements of Juniata River at Newport, Pa., 1899-1904. Date. 1899.

In 1890 regular daily observations of fluctuations of the water surface of the Susquehanna River at Harrisburg were started by E. Mather, president of the Harrisburg water board. These observa- HOYT ANDERSO ^o?.] FLOW OF SUSQUEHANNA AT HARRISBURG. 105 tions have been continuecl since that time and have been furnished through the courtesy of Mr. Mather. The gage, the zero of which is the low-water mark of 1803, is located at the pump house of the waterworks in the pump well, which is connected with the river by two large mains. The original readings are taken in feet and inches, and for convenience in computations have been reduced to feet and tenths. The first discharge measurement was made at this station in March, 1897, by Mr. E. G. Paul, who has carried on systematic measure- ments there since that date. The measuring section is at the lower side of the Walnut street toll bridge. The initial point for soundings is the upright at the end of the hand rail on the downstream side on the left bank. At this point the river is divided into two channels by Fosters Island, which at the measuring section is about 1,200 feet wide. Its banks are low and sloping and during extreme floods the island is submerged. At ordinary stages the left channel is 1,350 feet wide and is broken by six bridge piers. The right channel is 1,300 feet wide and is broken by seven piers. The main banks of the river are high. The bed is composed of a hard matei-ial and is permanent, except in the spans adjacent to the island. The velocity never becomes too slug- gish to measure. During the spring and summer of 1903 a new bridge was built across Susquehanna River at Market street, which is about 1,200 feet below the gaging section. The piers of this new bridge obstruct the channel of the river by between 10 and 15 per cent of the total cross section. The result of this obstruction, as shown by the dis- charge measurements taken since the erection of the piers, has been to back up the water, thus increasing the gage height at the Walnut street station. On account of this backwater the measurements taken during 1903 show that, in order to use the standard rating table after June 1, 1903, and until January 1, 1904, a deduction of 14 per cent is necessarj- in the daily discharges. The following table gives the data from which this deduction was made : Date. Gage height. Observed discharge. standard rating table dis- charge. Difference. Differ- ence.

[NO. 109. About January 1, 1904, the old piers which were standing at the site of the new bridge at Market street were removed^ so that the river channel was left in such a condition that the stage of the river at Walnut street bridge returned to the same condition that existed before the 1903 bridge was built. In the summer of 1904 certain changes and improvements were made at the pumping station, and a partial dam was made in the river just below the pumping station. The effect of this dam was to raise the apparent stage of the water at the gage. A correction was applied to measurements of discharge made prior to July 18, 1904, so as to eliminate the effect of the dam and alterations at the pump house upon the gage readings. On July 18, 1904, a standard chain gage was attached to the guard rail on the upstream side of the Walnut Street Bridge in the left- hand span. The datum of this gage is the low-water mark of 1803, ajid it is believed that it records trulj^ the stage of the river to that datum, and that the changes in bridges below and at the pumping station above do not affect the records obtained from it. The length of chain is 39.38 feet; the bench mark is on the left abut- ment at the top upstream outer corner of the bridge seat; its elevation is 32.99 feet above low water of 1803. Observations at the gage in the pumping station are made by the engineer, C. M. Nagle, each morning before starting the pump. Observations at the standard chain gage are made by Thomas Num- bers, toll collector, once daily.

Prom July 18 to the end of the year the readings were taken at the Walnrit Street Bridge. Beginning with April 1 the readings at the pump house were too high by 0.6 toot, owing to the fact that a cofferdam was built just below the intake. This correction has been applied; therefore the gage readings for the complete year are referred to the low-water datum of 1803. b River frozen over at 5 a. m. f Several ice gorges existed both above and below Harrisburg from January 24 to March 13.

Practically open conditions existed at the latter station (gee p. 18.S). 130 HYDKOGEAPHY OF SUSQUEHANNA BASIN. [no. 109. SUSQUEHANNA RIVER AT McCALLS FERRY, PA. The McCalls Ferry gaging station is located, as shown in PI. VIII, at a narrow and rocky part of Susquehanna River, about 20 miles above its mouth and 1 mile above the village of that name. It was established on May 17, 1902, by Boyd Ehle while investigating a power development there. For a considerable distance along this j)ortion of the river the bank on the York County shore is the retaining wall of an abandoned canal which can be overtopped only in the greatest floods. The Lancaster shore, on the opposite side, is made up of almost vertical rock, and the railroad which skirts it has never yet been flooded at this point. The gaging section first selected for the station is located at Dun- cans Run (A- A, PL VIII), where two islands, Hartman and Streepers, divide the river into three channels, ranging in width from 100 to 500 feet. At ordinary low water, however, two of these run dry, thus confining the discharge to the main or westernmost channel. The river bed at the section is composed of schistose rock, with some pro- jecting bowlders and large irregularities. The flow, however, is com- paratively free from the boils so common in a river of this character. The discharge measurements are made from a boat held in place by a rope stretched between the towpath and Streepers Island, the gaging points, 10 feet apart, being indicated bj'^ a tagged wire, which is also used for keeping the boat parallel to the current. In order to provide for measuring the large floods which occur in the winter and spring months a cable station was established bj^ Mr. Ehle in the fall of 1902, about 1,000 feet downstream from the Dun- cans Run section (B-B, PI. VIII). The banks of the river and the condition of the river bed are very similar to those at the upper sec- tion, though the latter is somewhat more irregular, as shown by PI. I, B. During the low- water period of the fall of 1902 a careful sur- vey was made of the section at the cable station, and a contour map with 1-foot intervals was prepared from which the effective areas could be accurately determined, thus eliminating the error in dis- charge due to possible inaccuracies in soundings made at the time of the measurements. The width of the stream at this point is about 1,300 feet, and the maximum depth during a gaging was 46 feet. The car cable, a f-inch 37-wire strand, with a span of 1,450 feet, is anchored to 3-inch ej^ebolts set in cement in the solid rock on either side of the river. A 2-inch turn-buckle is provided at the York County end to regulate its height above the water. A high cliff on one shore and a large red oak on the other give the cable a 10-foot clearance over the highest floods on record. The car which runs on the cable, as shown in PI. IX, B, accommodates two people, and is propelled by a crank, turning one of the sheaves. HOYT AND ANDERSON *] FLOW OF SUSQUEHANISTA AT m'oALLS FERRY. 131 Eighty feet upstream from the main cable is suspended a f-inch secondary cable, along which runs a trolley carrying a guy rope to hold the meter against the current (PL IX, A). Measuring points for this section are 50 feet apart and are indicated by red and white bands ijainted on the main cable, the intermediate distances being readily estimated by counting the revolutions of the sheave. The measurements at both of the above stations are referred to two permanent gages, designated Nos. 2 and 5. These are painted on the rock and give elevations directly above sea level. Gage No. 2 is located about three-fourths of a mile below the village of McCalls Ferry in the tailrace of the proposed power house and has been read daily since June, 1902. The records in the following tables have been referred to this gage. Gage No. 5 is placed about 2 miles below McCalls Ferry, at the foot of Cullys Falls, and was thus located in order to be entirely out of the influence of the proposed dam. One of the purposes of the extensive investigations carried on at McCalls Ferry was to obtain data for determining the coefficient of discharge over ogee-faced weirs under high heads, and it is for use in these investigations that gage No. 5 was established. The methods used in carrying on the work at the McCalls Ferry station were practically the same as those employed by the United States Geological Survey. Every effort was made to eliminate any source of error, and vertical velocity determinations were taken when- ever possible. At Duncans Run, in order to ge^ satisfactory ver- tical velocity curves, an 80-pound weight, with pulley and rope attached, was dropped to the bottom, so that the meter could be pulled down without being washed too far from the section. When the surface velocity or 0.6 method was used the results were reduced by coefficients determined from these vertical velocity curves. At the cable station the secondary cable with the aid of the guy rope made it possible to get vertical velocity measurements at exception- ally great velocities and depths. A No. 12 telegraph wire was found to be more satisfactory at such times for holding the meter than the insulated cable ordinarily used, as it offered less resistance to the current, would allow the meter to sink deeper, and being less bowed by the water would show more accurately its depth below the sur- face. In this way curves were obtained to depths of 20 feet and in currents of 10 feet per second. During the highest stages, when the velocity sometimes reaches 17 feet per second, readings could only be taken at the surface. These results were, however, reduced by coefficients determined from the vertical velocity curves for each measuring point. 132 HYDROGRAPHY OF SUSQUEHAISTNA BASTN. [NO. 109.

CHEMUNG EIVER AT CHEMUNG, N. Y.« A gaging statiou was established at tlie suspension bridge across Chemung River near Chemung station, September 7, 1903. Gage heights are taken each morning and night, by Daniel L. Orcutt, b^^ a chain gage attached to the bridge. Current-meter measurements which have been made, and the mean daily stage of the stream, are shown in the accompanying tables. The gaging station is located 1 mile upstream from the New York-Pennsylvania line, and is shown on the Waverly sheet of the United States Geological Survey's topo- graphic map of the country. Chemung River is formed at Painted Post, N. Y., by the union of Tioga and Cohocton rivers. The Cohocton branch lies entirely in the State of New York. Tioga River receives, just above its mouth, Canisteo River, a large tributary, which also has its drainage basin in New York to the south of the Cohocton. The drainage of Tioga River above the Canisteo is mainly in Pennsylvania. The concen- tration, just above Corning, of the storm waters of these three main branches favors the formation of excessive floods. Chemung River flows southeasterly through Corning, Elmira, and Chemung, crosses the State line, flows for a short distance in Penn- sylvania, then returns to New Yoi'k and again crosses to Pennsylva- nia near Waverly, finall}'- emptying into Susquehanna River near Athens, Bradford Countj^, Pa. The total length of the stream is about 40 miles, about 30 miles of which is in New York State. Che- mung River is a sluggish stream with low^ banks and a broad valley or flood plain, which is often overflowed. It was formerly paralleled by a canal taking its supply from dams across the stream. This has been abandoned and at present the largest water-power development on the main river is at Elmira. The topographic features of theSirainage basin are, as a rule, bold and broad. The hills rise within a short distance of the stream several hundred feet on either side, and the upland plateau is to a large extent wooded, with impervious soil, no lake storage, and few marsh areas. Tributaries are ramifj'ing and uniformly distributed, though not numerous, and dry gulleys or flood channels are common. Dikes have been erected in the cities of Elmira and Corning for pro- tection against floods. One of the highest recorded freshets in the stream occurred June 1, 1889. It was preceded by phenomenal rain- fall, on the night of May 31 and June 1, aggregating several inches in the course of a few hours. The discharge has been estimated at 67 second-feet per square mile from 2,055 square miles, or 138,000 cubic feet per second.* ■ a Data on pages 140-153, inclusive, from Supplement of 1903 Repoi-t of New York S tate E ngineer . bReport of Francis CoUingwoocl, C, E,, on The Protection of the Citj' of Elmira, N.

CAYUTA CREEK AT WAVERLY, N. Y. A record of the daily stage of Cayuta Creek at the Ithaca Street Bridge, a short distance below the milldam in Waverly, was kept by T. P. Yates, covering the period'lklarch 1, 1898, to March 31, 1902. Tlie accompanying tables show the observed distance from the refer- ence point on bridge to water surface, the mean of the several read- ings being used where more than one daily observation was taken, « Discharge measurements by means of floats were also made by Mr. Yates. Cayuta Creek drains a long, narrow valley extending from eastern Schuyler County in a direction somewhat east of southerly a distance of 30 miles, the stream crossing the New York State line at Waverly and emptying into Susquehanna River at Sayre, Pa. In cross section the valley consists of a plain about one-half mile wide, through which the stream flows, bordered on both sides by abrupt slopes rising 500 feet within a distance of 1 or 2 miles from the foot on each side, "Befei-ence point is top iron hand rail at left-hand side second iron post from left-hand end of bridge on upstream side.

Cayuta Lake drains an area of 1G.5 square miles at the head of the stream. The area of the lake is 0.78 square mile, and this constitutes the onl}^ storage in the drainage basin. The average width of the valley is about 6 miles. The conditions favor rapid concentration of the run-off in the main stream, there being no large branches. Maxi- mum floods result, however, only from rapid inflow of sufficient dura- tion to enable the waters from the whole length of the valley to reach the lower stretches of the stream at the same time. Cayuta Lake is at elevation 1,272 feet. The stream descends to elevation 800 feet at Waverly in a distance of 18 miles from Cayuta Lake, following the general trend of the valley, a limited amount of water power being- developed at small dams.

Y. Records of the flow of Eaton and Madison brooks, two small streams near the headwaters of Chenango River, are among the earliest, if not the fi.rst, systematic stream gagings in the United States. The flow of these streams was determined by John B. Jervis in 1835 in an investigation of water supply for the summit level of Chenango Canal, extending from Utica to Binghamton, and now abandoned. Tfe3 headwaters of Chenango River, including Eaton and Madison brooks and the storage reservoirs which have been constructed to supply the summit level of Erie Canal through Oriskany Creek, are shown on the Morrisville, Cazenovia, Norwich, and Pitcher sheets of the United States Geological Survey topographic map. Eaton Brook drainage basin is from 1| to 3 miles in width and 7 miles in length. It contains near its head Eaton reservoir, at an eleva- tion of about 1,430 feet. The slopes are steep; the soil is close tex- tured, with shale near the surface. Tributaries are few, and the fall is rapid. The soil and topography of Madison Brook are similar, the area con- sisting of rounded hill slopes with a somewhat more porous soil, greater breadth, and more tributaries than in the Eaton Brook area. It is stated that the Eaton Brook and Madison Brook gagings show only the volume of water passed downstream from the reservoirs. iRR 109—05 11 152 HYDEOGEAPHY OF SUSQUEHANNA BASIN. [NO. 109.

Proceeding upstream from along the feeder which enters Oriskany Creek at Solsville, the draft from the storage reservoirs was observed as follows : Leland Ponds, well drawn down, September 11, 1903, outflow about 9 second-feet, Chenango Feeder above inflow from Leland Ponds, September 11, 1903, about 30 se ond-feet. Approximate total diversion, 39 second-feet. The outflow from the several reservoirs proceeding upstream was approximately as follows: Madison reservoir, September 11, 1903, 10 second-feet. Flow in Chenango feeder at first bridge above Hamilton, also above Madison reservoir outlet, about 23 second-feet. The outflow from the remaining reservoirs in the Chenango River area, Kingsley, Bradley Brook, and Eaton reservoirs, respectively, was slight. Their combined outflow passes a diverting dam above Randalsville, the waste from which, together with waste and seepage from the feeder, enters the natural channel of Chenango River, The flow in this river channel at the bridge above Earlville September 12, 1903, was approximately 44 second- feet. PRECIPITATIOlsr. During the last few years the United States Weather Bureau has maintained about 47 precipitation stations in the Susquehanna River drainage area (see list on p, 160). The locations of these stations and of the gaging stations are indicated in flg. 1 (p. 11). In order to compare the relation of rainfall to run-off in the Sus- quehanna basin, the run-off at Harrisburg has been taken as repre- sentative of the whole basin, and that at Wilkesbarre and Williams- port as representative of the main stream above Sunbury and the West Branch, respectively. The rainfall stations are so distributed as to represent fairly well the conditions over each of these areas. Therefore, it is assumed that for any one month the mean rainfall over the whole of any of these areas is the mean of the monthly rainfall at the various stations in that area. Based upon this assumption, the monthly and yearly rainfall for each of the years when the run-off records are available has been determined, as shown in tables on pages 161-171. An examination of the tables on pages 156 and 157, which give a comparison of the rainfall and run-off above Harrisburg, shows that the mean annual rainfall over the drainage area varies from 31.4 to a Snow of November and December, 1904, on ground. HOTT AN ANDERSON °] PRECIPITATION. 155 44.3 inches, with a mean for the fourteen years of 39.4. This jaelds a run-off of from 16.6 to 29.1 inches, with a mean of 21.6. The amount of rainfall which runs off varies from 49 to 71 per cent of the total, with a mean of 54 per cent. The run-off is a minimum in August, September, and October, during which months it ranges from 5 to 30 per cent of the rainfall, and averages about 15 per cent. As complete snowfall data are not available, it has been impossible to allow for the snow storage, which accounts for the high percentages in the late winter and early spring. To fully account for this storage a cube of snow should be melted at the end of each month in order to determine the amount of water stored during that time. The quantity available for run-off during the following month would be the amount so determined plus the precipitation during the follow- ing month minus the amount left in snow storage at the end of that month. Unfortunatelj^ sufficient data of this kind are not available, and therefore no attempt has been made to account for this disturb- ing feature. The tables on pages 158 and 159 show that the conditions on the main stream above Wilkesbarre and the West Branch taken separately are practically the same as when taken together in connection with the entire river as referred to above.

Owing to the lack of hi^- water gagings on Susquehanna River, it became necessary to estimate the flood discharges by means of the slope formula, v=cy/Rs, using Kutter's formula to fix the value of c The 1889 flood is the highest on record, and as there remain raanj' of its high-water marks made by eyewitnesses along the railroad and canal above McCalls Ferry, Pa., the mean slope along this part of the ' river could be closely approximated. These marks consist of notches ! on posts, rocks, hotels, bridge piers, and locks, and their elevations were accurately determined, as shown on the proflle. Ten sections, located as shown on PI. XVIII, were then chosen f i-oin the contour map. These were selected so as to show as far as possible the average for the portions of the river represented, so that the mean slope between the nearest reliable high- water marks could be used in connection with them. The sections were carefully surveyed and sounded to determine their area and wetted perimeter. In order to get a value for n in Kutter's formula the slopes were measured on the west channel of the Duncans Run section during U. S. GEOLOGICAL SURVEY WATER-SUPPLY PAPER NO, 109 PL.

From the curves and table for Chenango River it is seen tliat the value of the coefficient for reducing velocity obtained by the six- tenths-depth method varies from 0.93 to 1.03, the mean being 0.984. The coefficient for reducing velocity obtained by the top and bottom method to that obtained from the vertical velocity curve varies from 0.96 to 1.13, the mean being 1.041, the error of this method increas- ing as the depth increases. The coefficient for reducing velocitj" obtained bj' the third method to mean velocity obtained from the ver- tical velocity curve varies from 0.96 to 1.03, the mean being 0.996. From the curves and table for Susquehanna River it is seen that the coefficient for reducing velocity at six-tenths depth to mean veloc- ity obtained from vertical velocity curves varies from 0.95 to 1.06, the mean being 0.992. The coefficient for reducing velocity bj^ the top and bottom method varies from 1 to 1.17, the mean being 1.068. The coefficient for reducing velocity obtained by the third method to mean velocity varies from 0.99 to 1.03, the mean being 1.005. It is seen from the result in these tables: (1) That the third method of obtaining mean velocity b}^ observing velocity one-half foot above the bed and one-half foot beneath the surface and at mid dexJth gives results agreeing very closely with that obtained from vertical velocity curves if the bed is smooth; (2) that results obtained by the top and bottom method agree quite closely with those obtained from vertical velocity curves if the depth is small and bed smooth, and that the error by this method increases as the depth increases; (3) that velocities obtained by the six - tenths - depth method are somewhat larger than those obtained from vertical velocitj* curves if the average depth is greater than about 4 feet. The series of vertical velocity measurements made at Harrisburg were taken on November 2, 1903. They consisted of 20 measure- ments at depths ranging from 3 to 8 feet and mean velocity varjing from 1.5 to 2.6 feet per second/X The results of these measurements are shown in the following table and by the curves on PI.

The error, therefore, introduced by holding the meter at 0.6 depth is only about 1 per cent. Second, the mean coefficient found for reducing top and bottom veloci- ties to mean velocities is 1.08. Third, the coefficient for reducing velocities by the integration method to mean velocity is 0. 98. Fourth, the coefficient for reducing toi3 velocity to mean velocity is 0.85. 198 HYDROGRAPHY OF SUSQUEHANNA BASTN. [xo. 100. All iuterstiidy of these various series of vertical velocity measure- ments shows that at these stations for depths iiji to about 10 feet and velocities not over 5 feet per second the depth of the thread of mean velocity is practically 60 per cent of the total depth, while for depths over 10 feet and velocities over 5 feet per second the depth of the thread of mean velocity becomes greater, averaging about 70 per cent of the total depth. The coefficient for reducing top velocities to mean velocity for depths under 10 feet and velocities under 5 feet is about 0.85, while for greater depths and velocities it increases to a maximum of about 0.92. The top and bottom velocities invariably give too small results, depending upon the roughness of the bed. Furthermore, it is found that although the depth of the thread of mean velocity may vary between 50 and 80 per cent of the total depth, the error caused by holding the meter at 60 per cent of the depth does not exceed 5 or 6 per cent, which is within the limits of the accu- racy one can expect in stream-measurement work.

No. of days deficiency HOYT AND ANDERSON. ] WATER POWER. 203 To use the two curves in con junction with each othei', enter the diagram with a certain gage heiglit, find where it intersects the gage- lieiglit curve, then follow the ordinate of this intersection until it cuts the discharge curve, and the discharge for that particular gage height is found on the right side of the diagram. Assuming that the discharges at the various points in this portion of the river vary in proportion to the drainage area above, one can readily determine by the use of the curves the conditions which may reason- ablj'- be expected at any point below Harrisburg. For example, sup- pose one wishes to know how many days during the mean year the discharge will be less than 5,500 second-feet at the Pennsylvania- Maryland line, where the drainage area is 27,150 square miles, or 13 per cent more than at Harrisburg. As the drainage area at Ilarris- burg is 88.6 per cent of that at the State line, 5,500 second-feet would correspond to a discharge of 4,870 second-feet at Harrisburg. From the full-line curve on PI. XXVII we find that for twenty days during the mean year the discharge is less than 4,870 second-feet at Harrisburg, or 5,500 second- feet at the Maryland-Pennsylvania line. By applying the following simple rule for horsepower it is possible to determine the probable power which could be -developed during a mean year at any point in the lower Susquehanna : Rule : Horsepower on the turbine shaft equals the discharge in sec- ond-feet multiplied by the fall divided by 11. This is based upon an assumption of 80 per cent efficiency for the turbines. Applying this to the above example, we find that for three hundred and forty-five daj^s during the mean year 500 horsepower for 80 per cent efficiency can be developed for each foot fall at the Maryland- Pennsylvania line. RULES FOR ESTIMATING DISCHARGE. The approximate mean monthly discharge in second-feet for any stream in the Susquehanna drainage basin, may be determined in either of two ways — First. Its drainage area in square miles can be taken from the table on page 15, or measured on a map, and multiplied by the monthly run-off in second-feet per square mile given in the tables of the nearest gaging station. Second. The monthly rainfall in inches for the district, as deter- mined from the tables on pages 161 to 171, can be multiplied by the per cent of run-off for that month at the nearest of the three gaging stations — Wilkesbarre, Williamsport, or Harrisburg — giving the total monthly run-off in inches. This result multiplied by one of the fol- lowing coefficients gives the mean monthly run-off in second-feet per square mile : For montli of 28 days 0. 9603 For month of 30 days . 8963 For month of 31 days. .' .8674 204 HYDROGRAPHY OF SUSQUEHANNA BASIN. [NO. 109. The drainage area in square miles may be found as before, and if multiplied by the above product will give the mean discharge of the stream for that month in second-feet.
