PART VI FUTURE DEVELOPMENT e b. Navajo Powerplant Consumptive uses according to records provided by the Navajo Generating Station averaged 20,600 acre-feet over the 1980 to 1983 period. The contract for sale of water out of Lake Powell allows for annual uses of up to 34,100 acre-feet. Salt River Project personnel feel that this ultimate use will be realized in future years. c. Gallup-Navajo indian Water Supply Project See discussion under New Mexico on page 39. The project will supply 7,000 acre-feet to the Arizona communities of Teec Nos Pos, Sawmill, Fort Defiance, Window Rock, and St. Michaels. Water could be made available on a temporary basis from the unused Navajo Powerplant allocation until either the powerplant uses the full contractual amount or the contract is renegotiated to a lesser amount. 2. Wyoming a.Mlscellaneous Additional Depletions e Values shown in the 1983 column of Table A represent addi- tional depletions that have developed since the Comprehensive Framework Study (1965 level) estimates were prepared. These values and the projec- tions to 2000 were provided by the Wyoming State Engineer's Office. The projections of irrigation beyond 2000 were made by Reclamation and assume a declining increase in new irrigated lands. The projections of municipal use beyond 2000 were made by Reclamation and assume the same rate of increase as that estimated for 1983 to 2000. b. Seedskadee Project Fontenelle Dam is the only feature of the project that has been constructed. Irrigation facilities have not been built, and there are no plans to reactivate studies to identify an irrigation project. By contract of June 14, 1962, the State of Wyoming pur- chased 60,000 acre-feet of capacity in Fontenelle Reservoir. The United States notified the State that the yield from the 60,000-acre-foot capac- ity would be available on January 1, 1969. The State optioned 25,000 acre-feet to Sun Oil Company and 35,000 acre-feet to Pacific Power and Light Company with 25,000 acre-feet as firm supply and 10,000 acre-feet when available. e A second contract, dated December 27, 1974, was signed with the State of Wyoming which would yield up to 125,000 acre-feet additional for Wyoming's use. Also, 135,000 acre-feet would be reserved for use of the United States, with 109,000 acre-feet marketable below the I-BO Highway Bridge and above the Green River water measurement gage. The total marketable yield from the reservoir is estimated at 281,000 acre-feet; however, present restrictions on reservoir drawdown imposed by the limits of riprap on the upstream face of the dam limit the maximum 32
