Show PART III FUTURE DEMANDS In general, the quality of surface water supplies is adequate for livestock use. With the small increase in water demand projected for livestock, no problems of any magnitude are foreseen within the Region. Local problems will continue to occur where groundwater supplies are not suitable, where present surface supplies are not adequate and storage methods are not practical. These problems are expected to occur only with range cattle, as livestock feeding operations are not likely to develop where the water supply is limited. Grand Junction's present source of supply, Kahnah Creek, has an annual discharge that is adequate to meet the 2020 municipal and indus- trial demands (18). However, the full use of the creek as a water supply may be impossible due to the projected agricultural and recreational uses. Consequently, other sources of supply may have to be developed. Two authorized projects that have been planned for the area will supply additional municipal and industrial water. With proposed developments, the annual discharge of the Animas River will be adequate to supply the municipal and industrial requirements of Farmington, New Mexico through 2020. Quality of water problems in the area will require careful attention. Use of Regional surface-water sources will be by far the most common means of meeting municipal and industrial water needs in the next several decades. A number of federal multi-purpose surface-water supply projects have recently been constructed, are under construction, or are planned for all major areas of expanding M&I needs in the Region. For example, the Bureau of Reclamation's Central Utah Project will supply municipal and industrial water in the Duchesne River Basin. The Animas-LaPlata Project will supply water in the Aztec-Farmington-Shiprock, New Mexico, and Durango, Colorado areas. Other projects from which new supplies .of M & I water will be available include the Glen Canyon, Flaming Gorge, Curecanti, and Navajo storage units; the proposed Dolores, Dallas Creek, San Miguel, West Divide and Yellow Jacket Projects in Wester Colorado, and the Green River Project in southwestern Wyoming. Because of the rural character of the Region, however, there are wide areas where small community systems will be developed by non-federal funds. This is especially true in the Utah portion of the San Juan-Colorado Sub- region. Programs of the Bureau of Indian Affairs, Department of Housing and Urban Development, and Economic Development Administration will by large be used to meet the Indian needs projected for Arizona and portions of the San Juan-Colorado Subregion. Other areas like the Wyoming portion of the Green River Subregion and the Utah portion of the Green River Sub- region south of the Duchesne River Valley have many small communities scattered over wide areas that will meet their needs through private development. 42 |
