<br />44 Chapter F-Present and Future Development <br /> <br />the year 2010 call for an annual depletion of <br />30,000 acre-feet. <br /> <br />Bullhead City <br /> <br />A contract was signed with Bullhead City for an <br />annual diversion of 8,200 acre-feet per year. <br />Bullhead City diverted about 4,600 acre-feet in <br />1987. Bpllhead City is expected to have an <br />estimated depletion of 15,000 acre-feet by 2010. <br />In order to meet projected water demands, the <br />State of Arizona has recommended that <br />Bullhead City will need a large contract <br />entitlement. <br /> <br />Clbola Valley Irrigation and Drainage District <br /> <br />A contract Wf!.S signed with Cibola Valley <br />Irrigation and Drainage District for an annual <br />diversion of 22,560 acre-feet. The Cibola Valley <br />Irrigation and Drainage District diverted about <br />28,200 acre-feet in 1987. Projections for the <br />year 2010 call for an annual diversion of <br />20,700 acre-feet with an estimated depletion <br />of 14,000 acre-feet. <br /> <br />Lake Havasu Irrigation <br />and Drainage District <br /> <br />Contracts exist with Lake Havasu Irrigation and <br />Drainage District for an annual diversion of up <br />to 14,500 acre-feet. The Lake Havasu Irrigation <br />and Drainage District diverted about <br />10,600 acre-feet from the Colorado River in <br />1986. Projections for 2010 show an annual <br />diversion of 12,000 acre-feet with an estimated <br />depletion of 7,000 acre-feet. <br /> <br />Central Arizona Project <br /> <br />The Colorado River Basin Project Act authorizes <br />the Central Arizona Project for the purpose of <br />furnishing irrigation and municipal water <br />supplies to the water deficient areas of Arizona <br />and western New Mexico through direct <br />diversion or exchange of water. This project is <br />now under construction with water deliveries <br />expected in 1992 to Tucson. This project will <br />provide water to Indian lands and a replacement <br /> <br />water supply to non-Indian lands now being <br />irrigated. Water made available to non-Indian <br />lands can be used only on lands having a recent <br />irrigation history. The Central Arizona Project <br />must withstand shortages up to its full <br />allocation if there is insufficient mainstream <br />water to satisfy an annual consumptive use of <br />7.5 million acre-feet apportioned under the <br />Supreme Court Decree of March 1964 to the <br />States of Nevada, Arizona, and California. <br />When shortages occur, diversions to the Central <br />Arizona Project will be limited to ensure senior <br />priority right holders of their entitled diversions <br />from the Colorado River mainstream water. A <br />maximum of 2.17 million acre-feet of Colorado <br />River water is all that could be diverted with a <br />canal capacity of 3,000 cubic feet per second. <br /> <br />In 1989, about 725,000 acre-feet were diverted. <br />Predictions for depletions vary; however, an <br />estimated full depletion level of about 1.5 million <br />acre-feet per year can be expected by 1993. <br /> <br />Colorado River Indian Reservation <br /> <br />The Colorado River Indian Reservation is <br />located along the Colorado River, just below <br />Parker Dam, with most of the land in Arizona <br />and the remainder in California. The Supreme <br />Court Decree allocated 717,148 acre-feet of <br />diversions t.o the Colorado River Indian <br />Reservation for irrigation of 107,588 acres of <br />land. There are 99,375 acres ofland in Arizona, <br />of which about 76,000 acres have been <br />developed. The consumptive use for irrigation of <br />these lands was about 358,700 acre-feet in 1987. <br />The Bureau of Indian Affairs has reported a <br />general2,OOO-acre-per-year land development <br />rate on the reservation in the past. The land <br />development rate of 2,000 acres per year was <br />assumed for the future even though the Bureau <br />ofIndian Affairs feels the land development rate <br />may slow in the near future. <br /> <br />Clbola Wildlife Refuge <br /> <br />The Cibola Wildlife Refuge has a water right <br />reserved by Secretarial notice in the Federal <br />Register, December 9, 1982, for 16,973 acre-feet <br />of consumptive use per year. In 1987, the refuge <br />
