Of the 13,500 acre- <br />feet (17 x 106m3) of uncommitted allotment, it ia expected that 7,000 <br />acre-feet (9 x 106m3) will be used by the Fort Mohave Indian Reserva- <br />tion while the remaining 6,500 acre-feet (8 x 106m3) has not been allocated. <br />It was projected for this report that this water would be utilized at the <br />rate of 2.500 acre-feet (3 x 106m3) by 19BO, an additional 2,000 acre-feet <br />(2 x 106mj) by 1990, and an additional 5,000 acre-feet (6 x 106m3) by the <br />year 2000. These other projects could include fish and wildlife uses, <br />additional energy requirements, and municipal and industrial projects. <br /> <br />17. Between Colorado River below Hoover Dam, Arizona-Nevada, and Colorado <br />River at Imperial Dam, Arizona-California <br /> <br />Mohave Steamplant. A portion of the Southern Nevada Water Project <br />allotment has been obtained via contractual arrangements by the Southern <br />California Edison Company for diverting up to 23,000 acre-feet (28 x 106m3) <br />annually from the Colorado River for thermal power production purposes at a <br />site about 3 miles (5 km) downstream from Davis Dam. Use of water until <br />July 1, 2006, by the Southern California Edison Company is in accordance <br />with two contracts - one with the State of Nevada and the Southern Califor- <br />nia Edison Company and one with the Water and Power Resources Service and <br />the State of Nevada. The depletions for the Mohave Steamplant in 197B <br />were 9,100 acre-feet (ll x 106m3). The anticipated total depletion for <br />the years 1980, 1990, and 2000 would be 123000, 18,000, and 23,000 acre- <br />feet (15 x 106m3, 22 x 106m3, and 28 x 106m ), respectively. No diversion <br />i. anticipated after 2006. The diversion is not shown under the Southern <br />Nevada Water Project since the point of diversion is below Hoover Dam. <br /> <br />Fort Mohave Indian Reservation. The Fort Mohave Indian Reservation, <br />located below Davis Dam, is allocated water by the Supreme Court Decree <br />to irrigate 18,974 acres (7689 ha) of land - 14,916 acres (6037 ha) in <br />Arizona, 2,119 acres (85B ha) in California, and 1,939 acres (785 ha) in <br />Nevada with a maximum annual diversion from the Colorado River of 122,648 <br />acre-feet (151 x 106m3). The consumptive use required for irrigation <br />of these lands is estimated to be 4 acre-feet per acre (12 000 m3/ha) <br />which would result in main-stream depletion of about 75,900 acre-feet <br />(94 x 106m3) annually. None of the reservation lands were developed as <br />of 1974. In 197B, 8,200 acres (3300 ha) of reservation lands in Arizona <br />and California had been developed, according to the Bureau of Indian <br />Affairs. The following table shows the depletion credited to the reser- <br />vation from 1974 to 1978 and the dramatic development of use of their <br />water rights. The development of land is not expected to continue at the <br />current rate. <br /> <br />57 <br />
