<br />are contemplated, The project has not been
<br />deauthorized and is considered on deferred
<br />status for planning purposes,
<br />
<br />Transmountain Diversions
<br />
<br />Three diversions presently export water out of
<br />the Colorado River Basin in Wyoming, The total
<br />transmountain diversions for 1991 were
<br />estimated at 19,000 acre-feet, The Ranger Ditch
<br />diverts about 500 acre-feet of water from North
<br />Savery Creek for delivery to Willow Creek in the
<br />North Platte River Basin, The Continental
<br />Divide Ditch diverts about 1,000 acre-feet of
<br />water from Little Sandy Creek to the North
<br />Platte River Basin, Diversions from the North
<br />Fork of the Little Snake River to the city of
<br />Cheyenne were 16,462 acre-feet for 1991.
<br />
<br />Industrial Uses
<br />
<br />The State of Wyoming recognizes the
<br />considerable potential that exists for increased
<br />industrial use of water for thermal electric
<br />generation, mining and processing, coal
<br />gasification, coal coking, natural gas chemical
<br />extraction, and oil shale development, It is
<br />expected that most of this water will be provided
<br />through contracts with the State for water out of
<br />Fontenelle Reservoir, See the discussion for the
<br />Seedskadee Project,
<br />
<br />Thermal Electric Power. . The Viva Naughton
<br />No, 1 unit was in operation in 1965, and its
<br />water use is included in the Comprehensive
<br />Framework Study value for thermal electric
<br />power, Records supplied by Utah Power & Light
<br />Company show an average annual net use
<br />(diversion less return flow) of 5,670 acre-feet
<br />over a 7-year period (1977-83) for all three units
<br />at Viva Naughton, About 4,000 acre-feet ofthis
<br />amount are used by unit Nos, 2 and 3, Records
<br />provided by Pacific Power and Light Company
<br />(now PacifiCorp) indicate a level of use of about
<br />25,000 acre-feet for all four units at the Jim
<br />Bridger Powerplant,
<br />
<br />The Wyoming State Engineer estimates that
<br />water uses for new thermal electric power
<br />generation will increase by 6,000 in 2010, Also,
<br />an additional 10,000 acre-feet of depletion will
<br />
<br />develop at the Jim Bridger Powerplant when
<br />transmission restrictions are lifted, Water for
<br />the Jim Bridger Powerplant is provided out of
<br />Fontenelle Reservoir under a contract with the
<br />State of Wyoming for up to 35,000 acre-feet per
<br />year, Water for the Viva Naughton Powerplant
<br />is developed from a private water right,
<br />
<br />
<br />Mineral. . Considerable development of the
<br />trona, oil, and natural gas industries has
<br />occurred in the Green River Basin since the
<br />Comprehensive Framework Study was made,
<br />The Wyoming State Engineer projects that
<br />depletions will increase from 40,000 acre-feet in
<br />1991 to 47,000 acre-feet by 2010, FS Industries'
<br />contract with the State of Wyoming provides
<br />water from the State's allocation in Fontenelle
<br />Reservoir for use in a phosphate fertilizer plant,
<br />A slurry pipeline carries phosphate ore from the
<br />mining area near Vernal, Utah, to the plant near
<br />Rock Springs, Wyoming, The slurry water is
<br />used and reused as process water,
<br />
<br />Coal Gasification. . The Wyoming State
<br />Engineer now estimates that by the year 2010,
<br />the coal gasification industry will deplete about
<br />2,000 acre-feet annually,
<br />
<br />Oil Shale. . Predictions with regard to the
<br />future development of the oil shale industry
<br />always involve a high degree of uncertainty,
<br />The Wyoming State Engineer estimates a
<br />depletion by this use of about 2,000 acre-feet in
<br />the year 2010,
<br />
<br />Projections of industrial uses beyond the year
<br />2000 are largely arbitrary and the figures
<br />provided should be used with caution, No
<br />attempt has been made to predict individual
<br />industrial uses,

<br />Adjusted Comprehensive Framework Study
<br />
<br />Several water uses listed in the table were
<br />included in the Comprehensive Framework
<br />Study, The Comprehensive Framework Study
<br />values in the table were adjusted by subtracting
<br />out the following values to avoid double
<br />accounting: Navajo Reservoir evaporation,
