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