Show southern Nevada. Mohave Power Plant, presently under construction, would supply 1.58 million kilowatts. Principal transmission lines projected for year 1980 are shown on the map following page 94. CONTINUING PROGRAM, 198l - 2020 Multipurpose Water Supply In 1980, an estimated 1.5 million acre-feet water deficiency may be overcome by continued ground-water overdraft and more effective utilization of water supplies. Water withdrawal requirements are pro- jected to increase from the 198O level of 11.0 million acre-feet to a level of 13.0 million acre-feet in 2020. Depletions will increase from 6.9 to 8.5 million acre-feet in the same period. The continuing water supply program will provide water to satisfy the increasing demands and to greatly reduce the ground-water overdraft. The only foreseeable method to effectively augment the regional water supply will be by importation from outside the Region. For reasons of efficiency and potential savings in costs, importation studies should include consideration of the needs of the entire Pacific Southwest area. The first augmentation consideration will be as stated in Title II of the Colorado River Basin Project Act: "The Congress declares that the satisfaction of the requirements of the Mexican Water Treaty from the Colorado River constitutes a national obligation which shall be the first obligation of any water augmentation project planned pursuant to Section 201 of this Act and authorized by the Congress." Previous reconnaissance studies have indicated that an augmentation of 1.8 million acre-feet would be required to meet the national obliga- tion to Mexico by the year 2000. Other basin augmentation considerations include the rate of development in the Upper Colorado Region, the needs of the southern portion of the California Region, and the dependability of the supply from the Colorado River. Augmentation proposals in the past have included surface water imports from various areas of surplus outside the Pacific Southwest area desalting of sea water, and precipitation management. Each of these alternatives should be fully explored prior to implementing an augmentation program. Precipitation management is being studied as a possible source of water for augmentation. The potential magnitude of water quantity that might be provided by this method is unknown, but would probably be 96 |
