PART VI FUTURE DEVELOPMENT e c. Upalco Unit, Central Utah Project The March 1980 Definite Plan Report and the May 1981 Supplement thereof estimated total depletion of 11,900 acre-feet. The control schedule dated August 1983 indicates Taskeech Dam completion in 1990 and initial filling to occur at that time. Primary uses are for municipal, industrial, and supplemental water for irrigation. All of the project depletion is expected to occur by 2000. d. Jensen Unit, Central Utah Project The Definite Plan Report was revised in 1976. The plan provided irrigation water primarily for supplemental service and water for municipal and industrial use. Evaporation and irrigation consump- tive use totaled 4,000 acre-feet in 1983. Total depletion is estimated at l5,000 acre-feet. The project depletion would gradually increase to the full amount by 1990. e. Uintah Unit, Central Utah Project e A report for certification of physical, economic, and financial feasibility dated April 1975 was certified by the Acting Secretary of the Interior on August 22, 1975; approved by the Office of Management and Budget on March 25, 1976; and forwarded to Congress on April 6, 1976. Project water supply uses are primarily for supplemental irrigation service to Indian and non-Indian lands, full service to Indian lands, and a minor amount for municipal and industrial use. Total depletions would be 28,000 acre-feet. Over the past few years, the Ute Tribal Business Committee has expressed various levels of interest for the Uintah Unit, potential developments on Leland Bench, and the Bonne- ville Unit mitigation package. On November 9, 1982, the Ute tribe sub- mitted to the Bureau of Reclamation an "Interim Exploration and Planning Agreement Regarding Ute Water Resources." This agreement, which allows for further development of a study and a plan for construction of Uintah Unit, has been agreed to by Reclamation. Since tribal attitude to de- velopment of a recommended plan is nonsupportive at this time and for the purpose of this report, depletions to the Colorado River System are those which were determined for the 1978 Definite Plan Report. It is unlikely that major facilities can be completed before the late 1980's. It is estimated the project depletion would occur by 2000. f. Emery County Project The Emery County Project as originally constituted de- pleted about 14,000 acre-feet. Utah Power & Light Company has contracted for 6,000 acre-feet of the project water for the Huntington Powerplant. Negotiations are underway between Reclamation, the power company, and the water district for the purchase of 6,000 acre-feet of additional project water by 1990. It is estimated that this has and will result in a decrease of Emery County depletions to 11,000 acre-feet in 1983 and 8,000 acre-feet in 1990. This assumes a 2 to 1 conversion rate, Le., 6,000 acre-feet of project water sold to Utah Power & Light Company will result in a 3,000-acre-foot reduction in irrigation depletion. e 46
