January 22, 1855, and by Executive order of November 22, 1873, and is divided into 109 allotments and a 2-acre school tract. The Indian population is 667, of whom 548 reside on the reservation. The project includes 4,192 acres, of which 277 acres are Indian and 1,414 acres are white owned; of the latter 750.1 are east and outside of the reservation.

The works consist of about 24 miles of bay dikes, with protective piling and tidegates to keep out salt water, 6 miles of dikes on both sides of the old Lumi Channel for the same purpose, 3 miles of dike on the west side of the Nooksack River, including a structure at the head of Lummi Channel to prevent flood overflows, and recently about 2 miles of main drain and some laterals.

The work was authorized by the act of March 18, 1926, the original construction was begun in September 1916, and concluded June 13, 1929. Damage was caused by floods and tides in February, November and December 1932, and again in June, October, November, and December 1933, again in April and December 1934. Repairs were in progress, but due to delay in securing funds the damage kept ahead of repairs. Finally additional funds were secured in June 1933, Federal project 430, $20,000, and contract approved July 12 for complete repairs and some drainage work to be completed before November 12, 1935.

The total cost including this work is $143,228, or about $34 per acre average.

A small maintenance fund is indispensable for the proper patrolling and maintenance of the works.

The land is very fertile and will produce extraordinary crops and will be s valuable asset, if protected. It is expected that ultimately the landowners will be able to pay for the entire maintenance, but the recent flooding of the land has made it impossible for the present.

The crops for the past few years were of an average value of approximately $80,000.

Collections were begun in 1930 and the small amount available each vear has been expended on maintenance and repair. The total collections to June 30, 1936. aggregate $2,987.91.

The operation and maintenance rate for 1930 to 1932 was 25 cents per acre and for 1933, 1934, 1935, and 1936, 40 cents per acre, the 15 cents additional being for repayment of a special appropriation of $8,000, reimbursable as operation and maintenance.

20. Administration, $60,000.—There are more than 100 projects involved, many of which comprise comparatively large areas of irrigable lands. On the larger and more complicated projects the irrigation division is in direct charge of the projects. On many of the smaller units the operation and maintenance is handled by the local superintendent.

The projects under the direct management of the division comprise a total irrigable area of approximately 1,032,000 acres, of which 670,000 acres are under constructed works and 410,000 acres are now being irrigated, of which ares 107,900 acres are irrigated by Indians. The projects for which the irrigation service has only advisory relations are in all instances small in area, the aggregate irrigable area being approximately 118,400 acres of which 56,720 acres are under constructed works and 37,330 acres are being irrigated, of which area 32,850 acres are irrigated by Indians.

For the proper administration of the irrigation activities the following principal field administrative offices are required: Assistant Director of Irrigation, Los Angeles, Calif.; and three district offices located at central points in each of the three districts into which the arid portion of the Indian country has been divided.

The headquarters for district no. 3, including Washington, Oregon, Idaho, Montana, Wyoming, North Dakota, and South Dakota, are located at Billings,


The headquarters for district no. 4, including California, southern Arizona, Nevada, and Utah, are located at Los Angeles, Calif.

The headquarters for district no. 5, including southern Colorado, New Mexico, northern Arizona, Oklahoma, and that part of Utah lying south of the San Juan River, are located at Albuquerque, N. Mex.

District no. 2 was abolished April 15, 1935, and the territory divided between districts 3 and 4.

The estimates included under "Administration" have been worked out on the basis of the administrative organization that would be required on a strictly operation and maintenance basis. Where further construction work is involved some additional expense will necessarily be incurred, which must be paid from funds available for construction work.

On each of the projects that are being operated and maintained by the Irrigation Division a local operating force is maintained. The expense of the various

ITEMS OF INCREASE IN ESTIMATE Mr. Johnson. There are only two changes of importance in that item. Please explain them briefly.

Mr. Dodd. On page 162 of the justifications, we show a number of small projects for which specific appropriations are not made. You will notice that there are 30,455 acres of irrigable land, and 14,532 acres in the area under constructed canals. For construction to date we have spent $811,637.52. With Public Works funds we have put in some other small irrigation projects, and this increase is to cover the small maintenance and operation costs of those projects.

The other item of increase is in the Pueblo item, where we go from $4,000 to $25,000, an increase of $21,000. Of that increase $4,000 is accounted for by the consolidation of the Zuni operation and maintenance item, which is bracketed out on page 116. That leaves an increase of $17,000, which Mr. Wathen will explain.

MAINTENANCE AND OPERATION OF GAGING STATIONS ON THE RIO GRANDE Mr. WATHEN. That is primarily for maintenance and operation of 58 gaging stations on the Rio Grande, installed under Public Works allotments. Those records are very necessary in connection with the probable early adjudication of water rights in the Rio Grande Valley, There is litigation now before the Supreme Court in this connection. The case is entitled “Texas v. New Mexico", but it indicates very clearly that complete checks will be made within the next year or two.

Mr. O'NEAL. This item is marked "Reimbursable”: Does thst mean that under this est mate you are making the Indians put up a certain sum to liquidate this cost?

Mr. Dopp. The Indians contribute a large amount of labor on the projects, and expenditures are made by the Government covering the cost of lumber and other materials needed for repairs in the project works.

Nir. O'NEAL. That is a regular charge?

Mr. Dopp. We have established a per-acre charge per year, which is usually $1 per acre. It is worked out on that basis.

Mr. O'NEAL. You do not have any funds coming out of these projects going into the Treasury, do you?

Nir. Dopp. No, sir; except in a few cases, one being the Ganado project, in Arizona, where we have some white people on the project. We collect from them $1,000 a year, or approximately that. Then at the Pala and Rincon, California, project, we collect $2,000 a year. From the Southern Ute project, in Colorado, we will collect about $4,000 a year

Mr. O'NEAL That money is covered into the Treasury.

Mr. Dopp. Yes, sir; and is reappropriated by this act. Section 4 of the Permanent Appropriations Repeal Act directed that those funds be corered into the Treasury and be reappropriated.

Mr. O'NEAL Then, we increase the amount spent on those projects br that amount.

Nr. Depp, So; that is included in the total herë. Prior to 1935, we spent that money without congressional review, but now you have it before you in this bill. If you will notice the language on page 116,

GENERAL DESCRIPTION OF PROJECT Irrigation system.--The San Carlos project is designed to irrigate 100,000 acres of which 50,000 acres are owned by whites and 50,000 acres are on the Gila River Indian Reservation and owned in part by individual Indians and in part by the Pima Indian Tribe as a whole. The white-Owned lands are mostly included in the San Carlos Irrigation and Drainage District. All of the white-owned lands are now under constructed works. Approximately 40,000 acres of the Indian lands are under constructed works.

During 1936, 24,813 acres were irrigated on the Indian part of the project, of which 23,428 acres were cropped and had a crop value of $306,063, or $13.06 per acre. On the white part of the project, 37,002 acres were irrigated and cropped with a crop value of $1,449,987, or $39.20 per acre. The total crop value was $1,756,051 or an average of $29.06 for the 60,430 acres cropped. The total number of acres irrigated was 61,813. During the early part of the present year, approximately 71,000 acres of land were being irrigated and cropped. It is expected that during 1938 about 80,000 acres will be irrigated and cropped with a crop value of approximately $2,500,000

The population of the project consists of 4,718 Pima Indians and approximately 7,000 whites, including those living in towns and villages. Those living on project farms include about 4,600 persons of whom approximately 2,600 are Pima Indians. It is expected that water will be delivered to 800 Indian farms farmed by the Indian owners and to 500 white owned farms. The principal crops are alfalfa for hay and pasture, cotton, wheat, maize, corn and pasture grasses. Water for irrigation is delivered practically every month of the year.

Power system.--The project has a hydroelectric power plant at Coolidge Dam and a Diesel-electric plant located near the town of Coolidge. High-voltage lines are constructed to transmit the power from the Coolidge Dam plant to substations within the project area and to mining customers on the San Pedro River. Low-voltage lines are constructed to transmit the power from project substations to project camps and shops, to project pumping plants, and to a few project industries and rural customers.

Project power was first delivered to the project in March 1935. The fiscal year 1936 was the first full year of the operation of the power system. The Diesel stand-by plant was completed in December 1935. During the fiscal year 1936, power generated by the hydro plant at Coolidge Dam amounted to 13,722,400 kilowatt-hours and by the Diesel plant, 3,609,810 kilowatt-hours. The total of all power generated was 17,332,210 kilowatt-hours. Power was purchased from outside power companies to the amount of 449,625 kilowatt-hours. Total power delivered to users was 15,657,234 kilowatt-hours. Of this the project used 10,379,701 kilowatt-hours in the operation of pumping plants in irrigation wells and 171,802 kilowatt-hours in project shops and camps. Five million one hundred and five thousand seven hundred and thirty-one kilowatt-hours of electric energy were sold to mines, project industries, and rural users.


DETAILED DESCRIPTION OF PROJECT WORKS The irrigation system to be operated and maintained consists of the following principal features:

Joint works.—This part of the system is operated and maintained for both white and Indian lands as follows:

1. Storage system. Consists of the San Carlos Reservoir on Gila River, having a maximum capacity of approximately 1,200,000 acre-feet, controlled by the Coolidge Dam.

2. Gila River regulation. This provides for the regulation and division of the waters of Gila River through a water commissioner appointed by the judge of the Federal district court.

3. Distribution system.Consists of the following features: (a) Ashurst-Hayden Diversion Dam which diverts water from Gila River into the main canal of the project; (6) main canal, which extends for 15 miles to the Pima lateral headinand delivers to laterals for white-owned lands and to the Pima lateral for distrig bution to Indian lands and white-owned lands; (c) Pima lateral, from the heading in the main canal, a distance of 12 miles to the east line of the Gila River Indian Reservation; (d) the Northside Canal that distributes water to both Indian and white-owned lands north of the Gila River.

4. Buildings and grounds.Project headquarters at Coolidge.

5. Telephone system, having 80 miles of line that connect project and district headquarters with field stations occupied by watermasters, ditch riders, patrolmen, the project machine shops at Olberg, and project power plants.

6. Power system.—The power system of the San Carlos project includes features as follows:

The hydroelectric power plant at Coolidge Dam is operated whenever water is being released from the San Carlos Reservoir. This plant has two units each capable of generating 6,250 kilowatt-hours of electric energy when working under the maximum head obtainable at the dam. The average capacity of the plant is about 5,000 kilowatt-hours at average levels of water in the reservoir and at average quantities of water released.

Diesel-electric stand-by plant, located 19 miles north of the town of Coolidge, consisting of two Diesel units each with a normal capacity of 930 kilowatt-hours.

Transmission lines consisting of 24 miles of 44-kilovolt line from Coolidge Dam to Hayden; 25 miles of 44-kilovolt line from Hayden, up the San Pedro River to Mammoth and Schultz; 85 miles of 69-kilovolt line from Hayden to the project, serving four transformer stations that are centers of distribution for the low voltage distribution lines, and 120 miles of 11-kilovolt lines extending from the substations to project pumping plants and to project works where electric power is used,

7. Irrigation and drainage wells.-There are 80 in number that are equipped with pumping plants and operated to provide a supplemental supply of water from underground waters. These wells are located on all parts of the project ang pump water directly into the project canal and lateral system. Water obtained from this source amounts to about 20 percent of the entire water supply. Electric power for the operation of these wells comes from project power plants and is delivered through project transmission lines.

Distribution system, white lands.—This feature includes canals and laterale distributing water only to the 50,000 acres of white-owned lands. The Picacho
