LANDS OPENED FOR IRRIGATION (No lands have been opened for irrigation by public notice. All lands are being irrigated under rental contracts.) CHRONOLOGICAL SUMMARY Reconnoissance and preliminary surveys made in 1907. IRRIGATION PLAN The irrigation plan of the Blackfeet project provides for five irrigation systems on the Blackfeet Indian Reservation, as follows: (1) The Carlow Canal system, heading on the right bank of Cut Bank Creek, and supplying water to about 18,000 acres of land near Carlow Station on the Great Northern Railway; (2) the Cut Bank Canal system, heading on the left bank of Cut Bank Creek, and supplying water to 20,000 acres of land, 11,000 acres of which are outside of the reservation and directly north of the town of Cut Bank; (3) the Two Medicine Canal system, diverting from the left bank of Two Medicine River, and supplying water to 48,000 acres of land; (4) the Badger-Fisher Canal system, diverting from the right bank of Badger Creek, and supplying water to 39,500 acres of land between Birch Creek and Badger Creek; and (5) the Birch Creek Canal system, diverting from Birch Creek, and supplying water to about 3,500 acres of land between Birch and Blacktail Creeks. The irrigable lands of the project are located in general in the southeastern portion of the Blackfeet Indian Reservation, between Cut Bank and Birch Creeks. The only portions of the above irrigation plan which have been completed are the Two Medicine Canal head works, 35 miles of the main canal, and 25 miles of laterals. Construction is in progress upon Two Medicine Lake Dam, the canals. and laterals of the Two Medicine unit, and upon the Badger feed canal of the Badger-Fisher unit. The Carlow, Cut Bank, and Birch Creek units of the project remain to be constructed on completion of the Two Medicine and Badger-Fisher units. CONSTRUCTION DURING FISCAL YEAR Two Medicine unit.-During the fiscal year surveys and investigations were made at Two Medicine Lake Dam, a construction camp was built, and preparations were made for starting construction. Excavation of the main canal and lateral systems was continued, and 21 miles of main canal and 25 miles of laterals were completed. The headworks of the main canal and all the principal structures on the first division were built. On June 30, 47 per cent of the construction work on this unit had been completed. Badger-Fisher unit. The construction of the Badger feeder canal was begun in June, 1911, and 66,500 cubic yards of material were excavated before June 30, 1911. During the year the headquarters of the project were moved from Family, Mont., to Seville, and a warehouse was built at the latter place. All construction work has been done by force account, principally with Indian labor and teams. OPERATION AND MAINTENANCE No water has been delivered for irrigation; but in May an operation force was organized on the Two Medicine unit, and water was turned into the canal for the purpose of priming the first 9 miles.
