The Continental Divide Ditch diverts about 1,000 acre-feet of water from Little Sandy Creek to the North Platte River Basin. Diversions from the North Fork of the Little Snake River to the city of Cheyenne were 23,422 acre-feet for 1993. Industrial Uses-The State of Wyoming recognizes the considerable potential that exists for increased industrial use of water for thermal electric generation, mining and processing, coal gasification, coal coking, natural gas chemical extraction, and oil shale development. It is expected that most of this water will be provided through contracts with the State for water out of Fontenelle Reservoir. See the discussion for the Seedskadee Project. Thermal Electric Power-The Viva Naughton No.1 unit was in operation in 1965, and its water use is included in the Comprehensive Framework Study value for thermal electric power. Records supplied by Utah Power & Light Company show an average annual net use (diversion less return flow) of 5,670 acre-feet over a 7-year period (1977-83) for all three units at Viva Naughton. About 4,000 acre-feet of this amount are used by unit Nos. 2 and 3. Records provided by Pacific Power and Light Company (now PacifiCorp) indicate a level of use of about 25,000 acre-feet for all four units at the Jim Bridger Powerplant. The Wyoming State Engineer estimates that water uses for new thermal electric power generation will increase by 7,000 acre-feet in 2010. Also, an additional 10,000 acre-feet of depletion will develop at the Jim Bridger Powerplant when transmission restrictions are lifted. Water for the Jim Bridger Powerplant is provided out of Fontenelle Reservoir under a contract with the State of Wyoming for up to 35,000 acre-feet per year. Water for the Viva Naughton Powerplant is developed from a private water right. Minerals-Considerable development of the trona, oil, and natural gas industries has occurred in the Green River Basin since the Comprehensive Framework Study was made. The Wyoming State Engineer projects that depletions will increase from 40,000 acre-feet in 1993 to 50,000 acre-feet by 2020. FS Industries' contract with the State of Wyoming provides water from the State's storage in Fontenelle Reservoir for use in a phosphate fertilizer plant. A slurry pipeline carries phosphate ore from the mining area near Vernal, Utah, to the plant near Rock Springs, Wyoming. The slurry water is used and reused as process water. Projections of industrial uses beyond the year 2000 are largely arbitrary, and the figures provided should be used with caution. No attempt has been made to predict individual industrial uses. New Mexico Adjusted Comprehensive Framework Study-Several water uses listed in table 3 were included in the Comprehensive Framework Study. The Comprehensive Framework Study values in the table were adjusted by subtracting out the following values to avoid double accounting: Navajo Reservoir evaporation, 26,000 acre-feet; Hammond Project irrigation, 10,000 acre-feet; and Four Corners Powerplant, 16,000 acre-feet. 26
