This bulletin presents the statistics of irrigation for the state of California collected at the census of 1920. Statistics of acreage irrigated, of acreage, yield, and value of crops grown on irrigated land, and of cost of operation and maintenance relate to the year 1919; other items relate to the year 1920. Throughout the bulletin figures for the census of 1910 are given for purposes of comparison; and, for the purpose of showing the historical development of irrigation, items which have been reported in censuses previous to 1910 are presented. Statistics of number of farms irrigated and of acreage, yield, and value of crops grown on irrigated land were collected in the general census of agri- culture. All other statistics were obtained in a special canvass of irrigation enterprises. Table 1.— SUMMARY FOR THE STATE: 1920 AND 1910. ITEM.

Farms irrigated. — The number of ' ' farms irrigated " is the number on which irrigation is practice!], and for the purposes of this in- quiry a "farm" is defined as for the general census of agriculture; that is, to be classed as a farm an establishment either must be 3 acres in extent or must have produced crops to the value of $250 in 1919, or must have required for its agricultural operations the continuous services of at least one person. "Number of farms irrigated" as used in this report and in that of 1910, is equivalent to the term "number of irrigators" used in census reports on irriga- tion previous to 1910. Irrigation enterprise. — An "enterprise" is an independent irri- gation establishment and includes the works for supplying water and the land to which water is supplied or is to be supplied, except that the cost or value of the land is not included in the "capital invested." Acreage irrigated, in enterprises, and available for settlement. — Acreage irrigated is the acreage to which water was actually applied in the season preceding the census year — 1919 for the Fourteenth Census and 1909 for the Thirteenth Census. Acreage to which enterprises were capable of supplying water relates to the season following the time of taking the census and, consequently, is based on estimates made by those controlling the enterprises. Acreage included in enterprises represents the extent of the plans of those controlling enterprises. Acreage of irrigated land reported as available for settlement relates to land within existing enterprises and not to land that is susceptible of reclamation and settlement by new enterprises or extensions of existing enterprises. Types of enterprises. — The types of enterprises under which all data are classified are as follows: ■J United States Reclamation Service enterprises, which operate under the Federal law of June 17, 1902, providing for the construction of irrigation works with the receipts from the sale of public lands. In addition to serving land within its own projects, the United States Reclamation Service supplies stored water to land within other enterprises. United States Indian Service enterprises, which operate under va- rious acts of Congress providing for the construction by that service of works for the irrigation of land in Indian reservations. Carey Act enterprises, which operate under the Federal law of August 18, 1894, granting to each of the states in the arid region 1,000,000 acres of land on condition that the state provide for its irrigation , and under amendments to that law granting additional areas to Idaho and Wyoming. Irrigation districts, which are public corporations that operate under state laws providing for their organization and management, and empowering them to issue bonds and levy and collect taxes with the object of obtaining funds for the purchase or construction and for the operation and maintenance of irrigation works. Cooperative enterprises, which are controlled by the water users under some organized form of cooperation. The most common form of organization is the stock company, the stock of which is owned by the water users. Commercial enterprises, which supply water for compensation to parties who may own no interest in the works. Individual and partnership enterprises, which belong to individual farmers or to neighboring farmers, who control them without formal organization. Capital invested. — The capital invested in irrigation enterprises is that reported by the owners. For the larger works the capital invested is taken, in most cases, from books of account and repre- sents the actual investment. In the case of most of the private and partnership and many of the cooperative enterprises, however, the works were built by their owners without records, of money or labor expended, and the capital reported represents the owners' estimates. The schedules used in 1910 called for "cost," while the schedule used in the present census calls for "capital invested," but the instructions accompanying the schedules make these two terms equivalent. In both cases the investment includes cost of construction and of acquiring rights. Tho latter usually ro.'isiste of filing fees only, but in some instances it includes the purchase price of rights. However, these cases are so rare that they arc unimportant. The co3t reported for 1900 is designated "cost of construction," but probably includes the cost of acquiring rights, as in 1910. For the Thirteenth and Fourteenth Censuses the aver- age cost per acre is based on the acreage which enterprises were capable of irrigating in the census year and the cost to tho date of the census — January 1, 1920, for the Fourteenth Census, and July 1, 1910, for the Thirteenth Census. Operation and maintenance. — Coat of operation and maintenance was not reported en all schedules, and averages are based on the acreages for which cost is reported. No estimate of total cost of operation and maintenance for all irrigation enterprises has been made. In the case of enterprises operating pumping piants the cost of operation and maintenance includes cost of fuel and attend- ance. Water rights. — The acreage irrigated has been classified by the character of rights under which water is received. The classes used are defined as follows: ''Appropriation and use" includes all rights acquired without formalities of any kind that have not been defined by the courts. ''Notice filed and posted" includes rights for which claims of some kind have been either posted or filed that have not been defined by the courts. "Adjudicated by court" includes all rights that have been defined by the courts. "Permit from state" includes all rights initiated under laws requiring any party wishing to acquire rights to obtain a permit from the state. "Certificate or license from (lie state" includes rights acquired under laws providing for the issuing by the state of certificates or licenses defining rights acquired. "Riparian rights" includes rights based on the ownership of riparian land. " Underground" represents water taken from wells. Source of water supply. — In classifying acreage by source of supply from which water for irrigation is obtained, in 1910 acreage was credited to what seemed to be the principal source of supply, while in the census of 1920 the attempt is made to represent the facts more nearly by presenting various mixed classes. Date of beginning. — The date of beginning of irrigation enter- prises is, in some cases, th9 date when construction began, and, in other cases, the date of filing a claim or of applying for a permit . If a filing or application for permit was made and work was begun and continued with reasonable diligence the date of filing is con- sidered the date of beginning, otherwise the date of construction is taken as the date of beginning. Drainage basin. — The drainage basin of a stream is all of the land drained by the stream and its tributaries. Units of quantity and capacity. — Capacities of canals, reservoirs, wells, pumps, and engines, and quantities of water used are ex- pressed in the units commonly used in engineering literature to express the same items. They are as follows: Capacities of canals and volumes of flowing water are given in second-feet, a shorter equivalent for cubic feet per second. Capacities of wells and pumps are given in gallons per minute. Four hundred and fifty gallons per minute equal 1 second-foot. Capacities of reservoirs are given in acre-feet. An acre-foot is the quantity of water that will cover 1 acre to a depth of 1 foot. It equals 43,560 cubic feet. Capacities of engines and motors are given in horsepower. One horsepower is the power required to lift 33,000 pounds through a vertical distance of 1 foot in 1 minute of time. IRRIGATION— CALIFORNIA . CLIMATIC CONDITIONS. In California both the amount and the seasonal distribution of precipitation have an important influence on the necessity for irrigation. The state has a very wide range in amount of precipitation, the average annual amount reaching about 60 inches in the northwestern part of the state and only 2 or 3 inches in the southeastern part. Throughout the state there is a well-defined wet season during the winter months and an almost entire absence of rain- fall in the summer months. The latter condition makes irrigation necessary for the growing of summer crops in some sections where the total precipitation would be sufficient if more evenly distributed through- out the year, while the concentration of the year's precipitation in a short period makes it possible to j grow some crops, particularly grain, without irrigation [ where it would not be possible if the rainfall were j distributed through the year. That part of the state lying north of San Francisco Bay, except a part of the Sacramento Valley, receives more than 20 inches of precipitation annually, and crops are grown both with and without irrigation, while the part of the state south of San Francisco Bay, except in the high mountains, receives less than 20 inches, and irrigation is generally practiced, al- though some crops are grown without it. In Sacramento Valley the average annual precipi- tation is between 15 and 20 inches, but practically all of this occurs in the winter. Grain crops are gener- ally grown without irrigation, and alfalfa, rice, and orchards are irrigated. In San Joaquin Valley the average annual precipi- tation is from 5 to 14 inches, and here most crops except grain are generally irrigated; while there are large areas of irrigated grain. In the southeastern part of the state desert con- ditions are found, the average annual precipitation being from 2 to 5 inches, and no crops can be grown without irrigation. Along the coast of southern California the precipi- tation is from 15 to 20 inches, and crops are quite generally grown both with and without irrigation. In the Sierra Nevada Mountains the snowfall in the winter is very heavy, and this maintains a good su mm er flow in most of the streams. The summer of 1919 was one of the driest on record and in some sections, especially in the San Joaquin Valley, this occasioned a shortage of water for irri- gation. WATER SUPPLY FOE IRRIGATION. In northern California, except the Sacramento Valley, the supply of water available for irrigation is limited, and the area irrigated is small. In the Sacramento Valley water is taken from the Sacramento and its tributaries, and while there is a shortage at times there is a very large supply of flood water available for storage. In the San Joaquin Valley, where the larger part of the irrigated land of the state is located, the water supply comes principally from San Joaquin River and its tributaries from the east which rise in the high Sierras. These rivers carry large volumes of water during the rainy season and in the early summer when the snow in the mountains is melting, but have a low discharge in the summer, so that there is usually a shortage of water in this season. While some storage has been provided, there is opportunity for much more, and efforts are being made to have the owners of existing enterprises combine to build reservoirs and coordinate their canal systems in such a way as to save the flood waters and make the largest use of them. Natural overflow and seepage from irrigation have brought the ground water near the surface in many places, and during recent years many wells have been sunk and water is pumped from them to supplement the supply from streams when they are low. There is opportunity for a large extension of irrigation from this source as well as from the storage of flood waters. In 1919 the water supply in this section was unusually short, and much land usually irrigated was not watered. In the coast region of southern California there are many short streams rising in the coast range and discharging into the Pacific. In some sections there is little opportunity for storage, and a large part of the water goes unused. In this section, as well as in other parts of the state, there are many wells, both flowing and pumped. The heavy draft on the underground supplies has lowered the ground water to such an extent that many wells that once flowed are now pumped, and the lift in pumped wells has greatly increased. This condition is being reme- died to some extent by spreading the flood waters over the gravelly lands where the streams emerge from the mountains, so that some of the water will find its way into the underground supply rather than waste down the stream channels. Similar work is proposed for the Coachella Valley, in southeastern California, where small areas are watered from wells. Imperial Valley is supplied from Colorado River. Although the water supply in the river is usually sufficient there is sometimes difficulty in getting the water from the river into the canal because of silting. Plans for storage and for relocating the canal are under discussion. A large area of land in this valley is available for cultivation and a large quantity of water is available for storage. There are other oppor- tunities in California to use water from Colorado River, where it forms the boundary between California and Arizona, and some land has been irrigated. Here, as in the Imperial Valley, the water supply is ample if storage is provided for the surplus flood waters. IRRIGATION— CALIFORNIA. Colorado River extends into or borders seven states, and there are conflicting claims as to the use of its waters that are delaying the construction of reservoirs. Attempts are being made to settle these conflicts through a compact between the states. Such a compact has been authorized by Congress. FARMS AND ACREAGE IRRIGATED.

Not included in classification in 1910 ACREAGE, BY CHARACTER OF ENTERPRISE. California was the first state to enact an irrigation district law containing the provision for issuing bonds that are a lien on the lands within the districts. The so-called "Wright Act," containing this provision, was enacted in 1887, and has served as a basis for practically all irrigation district legislation in the United States. Many districts were organized under this act, oidy a few of which, however, have survived to the present time. Prior to the enactment of the Wright Act there were some districts created by special act, and there was a special law providing for the organization of districts, without the bonding power, in Los Angeles County. The Wright Act was amended and reenacted in 1897, the new law being known as the " Bridgeford Act." This law has been amended in various par- ticulars by almost every legislature since its passage, but is still in force. In 1915 there was enacted a law creating a State Irrigation Board, which was empowered to organize "water districts" under state supervision, rather than county supervision, as was done under the older laws, but this law has been declared unconstitutional by the state supreme court. Many irrigation districts in California have been organized to build irrigation works, and some have taken over works built by other agencies. The lands in the Imperial Valley have been organized into an irrigation district, which controls the diver- sion works and the main canal, while mutual com- panies control the distributing canals. This land is reported under "Cooperative" in Table 5. California accepted the conditions of the Federal Carey Act (act of Aug. 18, 1894) in 1915, providing for a "Carey Act Commission" and for the organiza- tion of "state irrigation districts" to reclaim Carey Act lands. However, no land is reported as irrigated under this law. In 1917 California enacted a "land settlement" law, providing for the building of irrigation works and other improvements, including dwellings, etc., by the state, and the sale of the farms created on long-time and easy terms to settlers. Only one enterprise had advanced far enough to be reported in the Fourteenth Census, and this appears under "State" in Table 5. Other projects have been begun. Most of the cooperative enterprises reported in Table 5 are mutual water companies supplying water to members only. Commercial companies in California are subject to control by the state railroad commission as to rates charged and conditions of service. IRRIGATION— CALIFORNIA .

The laws of California relating to water rights are summarized in the following paragraphs: In 1S50 California adopted the common law of England, but with- out specific mention of water rights. The first legislation in California relating to water rights was the net of 1872. This act provided that rights to water "flowing in a river or stream or down a canyon or ravine may he acquired by appropriation in the manner provided by law"; that the appropria- tion must be for some useful or beneficial purpose; that as between appropriators the "first in time is the first in right " ; and that the ap- propriator must post a notice at the point of intended diversion and tile a copy in the county records. This law was in effect until 1913. The constitution of the state, adopted in 1879, contained the following section relating to water rights: "The use of all waters now appropriated, or that may hereafter be appropriated, for sale, rental, or distribution is hereby declared to be a public use, and subject to the regulation and control of the state, in the manner to be prescribed by law." (Art. XIV.) While ill o i inistif ution am! laws provide for rights being acquired by appropriation, the courts of the state have recognized riparian rights under the law of 1850 referred to above. (Lux v. Haggins, 69 Cal., 255.) In 1913 California adopted a new system of public control of the use of water and attempted to eliminate the conflict, between ripa- rian rights and right by appropriation by providing that owners of riparian lands must, put water to use in order to retain their rights. The section of the law rein! i tig to this point is as follows: "Section 11. All water or the use of water which has never been appropriated, or which has been heretofore appropriated and which has not been in process, from the date of the initial act of appropriation, of being put, with due diligence in proportion to the magnitude of the work neces- sary properly to utilize for the purpose of such appropriation such water or the use of water, or which has not been put, or which has ceased to be put to some useful or beneficial purpose, or which may hereafter be appropriated and cease to be put, to the useful or bene- ficial purpose for which it was appropriated, or which in the future may be appropriated and not be, in the process of being put, from the date of the initial act of the appropriation, to the useful or beneficial purpose for which it was appropriated, with due diligence in pro- portion to the magnitude of the work necessary properly to utilize for the purpose of such appropriation, such water or the use of water, is hereby declared to be unappropriated. And all waters flowing in any river, stream, canyon, ravine, or other natural channel, excepting so far as such waters have been or are being applied to useful and beneficial purpose upon, or iu so far as such waters are or may be reasonably needed for useful, and beneficial purposes upon lands riparian thereto, or otherwise appropriated, is and are hereby declared to be public waters of the state of California and subject to appro- priation in accordance with the provisions of the act. If any portion of the waters of any stream shall not be put to a useful or beneficial purpose to or upon lands riparian to such stream for any continuous period of 10 consecutive years after the passage of this act, such non- application shall be deemed to be conclusive presumption that the use of such portions of the waters of such stream is not needed upon said riparian lands for any useful or beneficial purpose; and such portion of the waters of any stream so nonapplied, unless otherwise appropriated for a useful or beneficial purpose, is hereby declared to be in the use of the state and subject to appropriation in accord- ance with the provisions of this act." The new law created a water commission, and provided that parties wishing to take water should apply to the water commission for permission to do so, and that the commission should issue licenses on completion of the works in accordance with the permits. The law of 1913 provided also for the preparation by the com- mission of findings regarding rights to water, which were to be tiled with the courts and were to serve as bases for adjudications of water rights. This part of the law was amended in 1917, changing the procedure and providing that the findings of the commission shall be filed with the courts, and shall be issued as decrees by the courts, after hearings and such changes as the courts may make. After a decree is rendered the commission is to issue to each claimant a certificate setting forth his rights as determined by the court. An act of 1917 provided that after three years' nonuse of water for the purpose for which it was appropriated or adjudicated "such unused water shall revert to the public and shall be regarded as unappropriated public water." The portion of the law of 1913 relating to the acquiring of rights is in operation, but the commission is delaying any action for adjudication of rights until the expiration of 10 years from the passage of the act. when rights attaching to riparian lands but not utilized mil have expired under the terms of the act.

The report of a special census taken in 1902 pre- sented all data by drainage basins rather than by counties. The results of the census of 1920 have been tabulated on the same basis, and the data for 1902 are presented for purposes of comparison. For no other census have the results been tabulated in this form. The acreage reported for each drainage basin in 1919 comprises all the irrigated land in that drain- age basin, including that watered from springs and wells. In the 1902 results the acreages irrigated from springs and wells were not reported for the smaller tributary streams, but the acreages for the tributaries were included in those reported for the main streams. This area is so small, however, that the comparison of the areas reported for the tributary streams is not seriously affected.
