Show CHAPTER II 45 C.5.1 Yurna Auxiliary Project (Unit B) Water Use The Unit B water delivery contract contains no specific reference to the quantity of water to be delivered to it. Instead, it has provisions similar to the Gila Project contracts with Yuma Mesa and the North and South Gila Valleys regarding the quantity of water and a limitation of not more than 100 ftVs in the capacity of the works used in delivering water. In 1975, 1976, and 1977, the District consumptively used 37,436, 37,225, and 36,726 acre-feet of water, respectively; i.e., diversions less measured return flows. This included 893 acre-feet delivered to two small contractors in 1975, 949 acre-feet delivered in 1976, and 650 acre-feet in 1977. C.6 Other Arizona Water Delivery Contracts On November 14, 1968, Secretary of the Interior Udall signed the following water delivery contracts with: Contract Quantity Quantity of water used Contractor of Water 1975 1976 1977 CityofKingman not to exceed 18,500 a.f. - 0 - - 0 - - 0 - Mohave Valley IDD not to exceed 51,000 a.f. 18,806 a.f. 14,598 a.f. 24,936 a.f. Lake Havasu IDD not to exceed 14,500 a.f. 7,267 a.f. 7,327 a.f. 7,524 a.f. not to exceed 84,000 a.f. The total of 84,000 acre-feet contracted for represents 3 percent of Arizona's 2.8 maf allotted to it in Arizona v. California. The Kingman and Lake Havasu contracts are for M&I use while the Mohave Valley contract is for both irrigation and domestic uses. The contracts impose a charge of 25 cents per acre-foot for domestic water. The city of Kingman has not yet begun diversions, primarily because of the costs of pumping; i.e., the city is about 2,650 feet above the maximum water surface elevation of Lake Mohave. Nor do the other two contractors; i.e., the Districts, which are adjacent to the Colorado River, directly divert surface water from the river, but their use of ground water is established by their contracts as use of Colorado River water. Three other water delivery contracts have been executed. These are: Contract Contractor No. Date Quantity of Water Lakeside Utilities 7-07-30-W0001 April 1, 1977 120 acre-feet Holiday Harbor Utilities 7-07-30-W0003 June 16, 1977 200 acre-feet Ehrenberg Improv. Assoc. 7-07-30-W0006 October 14, 1977 500 acre-feet The City of Yuma has a water delivery contract, No. 14-06-W-106, dated November 12, 1959, which provides for the delivery of not more than 50,000 acre-feet per year of Colorado River water which is to be delivered immediately below Imperial Dam. Because of water delivery and salinity problems, the city executed an amendatory contract with the United States and the Yuma Valley County Water Users' Association on December 14, 1977, No. 14-06-W-106, to change the Imperial Dam point of delivery and to take delivery of water through the All-American-Canal, the Yuma Main Canal and the Valley Division's East Main Canal. The contract has the approval of the Imperial Irrigation District, which will carry the city's water through the All-American Canal. In 1975, 1976, and 1977, the city consumptively used 7,144, 6,782, and 8,212 acre-feet of water, respectively; i.e., diversions less measured return flows. |
