prior to the present organization of the irrigation service, and for which no cost reports are available. These amounts represent the total expenditures on the reservations indicated and in some instances include several different projects or systems.

It is proposed to make the analysis of these expenditures and to submit further details thereof in the next annual report.

The Indian irrigation service is divided into five districts, as shown on the inclosed blue-print map. The work in each of these districts

is in charge of a superintendent of irrigation, who has general supervision of all of the projects, surveys, and other matters pertaining to irrigation, water resources, and power development on Indian reservations in the respective districts.

The principal projects in each district are under the direct charge of an engineer or assistant engineer who reports to the superintendent of irrigation of that district. The superintendents of irrigation report to the chief inspector of irrigation whose headquarters are in Washington, and who has general supervision of all the irrigation projects

and matters relating thereto. He is assisted in this work by the assistant inspector of irrigation.

For purposes of convenience, tabulation of data is made by districts, and a summary of all the districts follows: The principal projects in district 1 are those on the Colville, Klamath, and Yakima Reservations. On the Colville Reservation surveys have been in progress for about 18 months to determine plans for and estimated costs of any feasible irrigation projects so that appropriate action for the protection of the water rights might be taken prior to the opening of the surplus unallotted lands to entry, as provided by law. The total cost of the surveys to June 30, 1914, appears to be $13,149.93. The data has not been completed and at the close of the fiscal year was in progress on the eastern part of the reservation; but the projects so far found feasible would irrigate an area of 17,900 acres at an estimated cost of $616,515.

A very large part of the lands under the proposed systems will be very valuable for fruit culture when provided with irrigation, similar lands somewhat more favorably located as to transportation facilities being now worth from $200 to $700 per acre. The remainder of the irrigable area with a water right is estimated to be worth $150.

On the Klamath Reservation the Modoc Point project has been under construction, and at the end of the fiscal year was nearing completion. This project will irrigate at the present development 6,200 acres of land, and if extended as contemplated would irrigate a total of 8,340 acres at an estimated additional cost of $40,000.

Surveys have been made for agency ditch to irrigate 7,000 acres at an estimated cost of $50,000. For a project near Chiloquin to irrigate 625 acres the estimate has not yet been made, and for the Yainax project surveys have not been concluded.

Investigations have been in progress to determine the feasibility of draining the Klamath marsh, of about 80,000 acres in extent, but no conclusion has been reached.

All of the irrigable area on the Klamath Reservation is estimated to have a value of from $30 to $50 per acre when irrigated.

There are four principal projects on the Yakima Reservation to irrigate approximately 180,000 acres of land. The largest of these is the Wapato project, for a part of which Congress in the act of August 1, 1914 (supra) has provided a water supply and upon which a special report will be made.

In the northern part of the reservation is the Ahtanum project irrigating about 5,000 acres of allotted lands, and south and west of the Wapato project is the Toppenish project to cover about 15,000 acres, and the Satus project to irrigate 40,000 acres of land.

The details of the Toppenish and Satus projects have not been worked out, and the work of completing a compilation of necessary data will be continued during the fiscal year 1915.

All of the land on the Yakima Reservation will produce abundantly with proper irrigation and is practically worthless for agricultural purposes without irrigation.

In district 2 the first item in the table is the Carson Sink allotments. This represents the reclamation and maintenance charges paid to the United States Reclamation Service on account of 4,640 acres of land in the Truckee-Carson project, Nevada, reserved for allotments to Paiute Indians. The construction charge is $22 per acre and is pay

able in annual installments of $2.20 per acre. The maintenance charge varies from 40 cents to 75 cents per acre during the time payments have been made. Payments of this kind have been made from the general irrigation item carried in the Indian bill, and it appears that $57,536 will be required to complete the payments for construction and make the payments for maintenance which will accrue during the period when construction payments will have to be made.

On the Fort Hall project, Idaho, the work during the fiscal year 1914 consisted of maintenance and operation only. This project was practically completed a few years ago with the exception of such minor extensions and regulating devices as will be required when the lands are put under cultivation. This project will irrigate a total of 50,000 acres, of which 38,000 acres is allotted to Indians. The remainder, 12,000 acres, is land under private ownership on the ceded part of the reservation, which lies contiguous to the town of Pocatello, Idaho. The total cost of the Fort Hall project appears to be approximately $812,000, or about $16 per acre of land which may be irrigated. This cost does not include $90,000 paid to the Idaho Canal Co. for the water right in Snake River for this project nor for the work done on Indian ditches prior to the beginning of work on the present project. Though the cost per acre for construction of the project is approximately $18, if all charges be included, Congress has provided in the act of April 4, 1910 (36 Stats., 274), lands under private ownership shall pay only $6 per acre for water rights, including construction charges. Under this provision the total reimbursement to the United States of the appropriations made for this project in the act of March 1, 1907 (34 Stats., 1024), and acts subsequent thereto aggregating $725,000 will not exceed $300,000, even if the Indian lands be required to pay a similar amount. The appropriations for constructing this project are required to be reimbursed to the United States from the sale of water rights, and it therefore appears that only a fractional part of the total cost of the project is to be reimbursed.

The Pyramid Lake Reservation, Nev., contains an area of 3,300 acres of land which may be irrigated by the construction of diversion and distribution works at an estimated cost of $85,000. This project contemplates diversion from the Truckee River, and it is believed that funds should be provided and construction begun at an early date. This is very valuable land and produces well when irrigated.

On the Uintah Reservation in Utah irrigation systems have been constructed to irrigate 87,880 acres of allotted land at a cost of $872,066.66. The situation on this reservation will be made the subject of a separate report.

The other projects in district 2 are small in extent and require no special mention.

District 3 includes the States of Montana and Wyoming. All of the projects in this district are large and construction has been in progress for a number of years.

The Blackfeet, Flathead, and Fort Peck projects will be made the subject of a separate report, as required by the act of August 1, 1914. On the Crow Reservation work during the fiscal year was confined to maintenance, including rebuilding of old wooden structures and repairs to ditches. In addition to this work the agency dam across the Big Horn River was rebuilt. These systems provide irrigation facilities for 68,756 acres, of which 13,398 acres are under cultivation,

8,539 of which are being cultivated by Indians. In addition to the land irrigable under the system constructed by the Indian Service water rights for 4,768 acres of allotments have been purchased in the Two Leggins canal, which diverts water from the Big Horn. River near Hardin, Mont. A small area of land under this canal remains to be provided with water rights. Actual construction has been limited to work necessary to convey water to such land as was thought would be irrigated presently.

On the Fort Belknap Reservation the total irrigable area under the systems appears to be 30,000 acres, which has been completed with the exception of minor laterals and structures. It is proposed to construct these as the demand for water arises.

The Shoshone Reservation systems will be made the subject of a separate report in compliance with the act of August 1, 1914 (supra). On the Tongue River Reservation the work during the past year was restricted to maintenance, as plans for future development of this project have not been completed.

District 4 includes the southern part of California and the southern part of Arizona. Work during the year has been in progress on a number of reservations or projects, as shown by the table.

The Colorado River project consists of a pumping plant and distribution system. It has been practically completed so as to provide irrigation for about 5,000 acres of land, and is so designed that it may be enlarged by the installation of an additional pumping unit, or it may be included in any large system for the reclamation of approximately 150,000 acres of irrigable land on the reservation. The actual area irrigated appears to be 697 acres.

Work on the Fort Mojave Reservation has consisted of repairs to the dike constructed jointly with the Cotton Land Co. for the protection of irrigable lands from damage by floods in the Colorado River. Notwithstanding the joint efforts to prevent the damage the flood of this last spring overtopped the dike, and it is believed that further expenditure of money for this purpose would be inadvisable until some large comprehensive scheme to regulate at least the peak of the floods can be found.

The surveys on the Gila Bend Reservation were made for the purpose of protecting the Indians' right to water from the Gila River and, if possible, to determine upon some plan to secure additional water for them.

The surveys have been conducted all along the Gila River in preparation for presenting the Government's side of a suit for the adjudication of water rights in the Gila River. This work was not completed and is still in progress. It is being conducted with the funds appropriated under the act of August 1, 1914, supra, for investigations recommended by the Board of Engineer Officers of the United States Army to determine the water supply available for the San Carlos irrigation project. This work will probably be completed during the fiscal year 1915.

Work has been in progress on the Papago Indian Reservation and on land reserved for Papago Indians south and west of Tucson, Ariz. On the Pima Reservation the irrigation pumping project in the vicinity of Sacaton has been maintained and the lateral ditches have been extended. The total area irrigated under this project appears to be 3,960 acres.

H D-63-3-vol 106- -7

Work has been in progress also on other Indian ditches claiming water rights of early priority under which 6,033 acres of land have been irrigated during this fiscal year. With the completion of this work it is expected that the actual area irrigated by Pima Indians will be increased to that formerly irrigated by them.

The work on the various reservations in California and other work shown on the table would seem to require no special mention.

District 5 includes the northern part of Arizona, all of New Mexico, and the Ute allotments in southwestern Colorado and southeastern Utah.

In addition to irrigation projects in progress as shown by the table, work of developing a water supply for Navajo and other Indian lands in New Mexico and Arizona has been in progress. In this work there are five well-drilling outfits, each in charge of a foreman who is responsible to the superintendent of irrigation of this district. This work is not for irrigation, but to provide a supply of water for domestic and stock purposes, in order that the immense grazing area without water supply may be utilized.

On the Pueblo Reservations one well rig has been in operation during the fiscal years 1913 and 1914. Twenty-two holes, aggregating 1,382 feet in depth, have been drilled which have proved good wells, and 11 holes, aggregating 737 feet in depth, have been drilled which have furnished bad water or none at all.

Work on the Navajo and Moqui Reservations has been in progress during the past three fiscal years. The results accomplished to date are 54 good wells, aggregating a depth of 3,911 feet, and 53 dry wells and those furnishing bad water, aggregating a depth of 4,149 feet. One deep-well outfit drilled 1,308 feet at Keans Canyon in 1912 and 1913 with unsatisfactory results, and is now located in the Choiska Valley, about 9 miles from Tohatchi. The first well drilled to secure water supply for use in operating the rig during the drilling for artesian supply was carried 294 feet deep without developing water. The second hole 225 feet deep secured good water. Drilling on the deep well will be continued during the fiscal year 1915.

The Hog Back project on the San Juan Reservation will divert water from the San Juan River for irrigation of about 4,000 acres of land. The original estimate of this work was $140,000, but, owing to the great amount of damage sustained to the canal from extraordinarily high floods, the cost will exceed this amount.

Work has been in progress on the irrigation system to irrigate the allotted lands of Southern Ute Indians in Colorado. Under the plan approved by this department those Indians who have allotments without irrigation facilities will be moved to the Pine River Valley and provided with irrigable lands, in order that they may have proper supervision and that the expense of constructing and maintaining numerous small ditches can be avoided. In carrying out the plan of constructing ditches in this valley for the irrigation of sufficient lands to provide each Southern Ute allottee with a 40acre tract with water rights the Morrison ditch was purchased, and the work of enlarging and extending this ditch has been under way during the fiscal year 1914.

On the Southern Ute diminished reservation a small ditch was taken out of the Mancos River a few years ago, but the Indians
