<br />ultimate contractible yield from Round II sales
<br />of 44,700 acre-feet by 2020, Depletions were
<br />computed assuming 100 percent consumption of
<br />industrial water and 40 percent consumption of
<br />water delivered to municipal and domestic users,
<br />
<br />Blue Mesa Contracts
<br />
<br />The Upper Colorado Regional Office of
<br />Reclamation and the FWS have determined
<br />that, at the current time, up to 10,000 acre-feet
<br />of water can be contracted for industrial
<br />purposes from Blue Mesa Reservoir, It has been
<br />assumed that this water will be supplied by
<br />2000 and that it will be consumed 100 percent,
<br />
<br />011 Shale
<br />
<br />Projections of water depletions for oil shale
<br />development contain a high degree of
<br />uncertainty, Values shown in the table were
<br />provided by the Colorado Water Conservation
<br />Board, For the present, Reclamation has chosen
<br />to assume that development will be deferred by
<br />one decade, so all depletion values have been
<br />postponed 10 years, These values do not include
<br />water contracted out of Ruedi Reservoir for the
<br />oil shale industry,
<br />
<br />Wolford Mountain, Bluestone, and Green
<br />Mountain Sales
<br />
<br />These projects and depletion values have been
<br />added to the depletions on table 3 at the
<br />suggestion of the Colorado River Water
<br />Conservation District, Wolford Mountain is
<br />located on Muddy Creek, a tributary of the
<br />upper Colorado River near Kremmling, It will
<br />be operated to provide transmountain exchange
<br />water for M&I uses, a variety of west slope uses,
<br />and recreational purposes,
<br />
<br />Bluestone is located near De Beque and will be
<br />used for industrial and oil shale purposes, Sales
<br />of water from Green Mountain Reservoir will be
<br />used for irrigation, snowmaking, and other
<br />purposes through direct delivery, augmentation,
<br />and exchange,
<br />
<br />Craig-Hayden Powerplants
<br />
<br />
<br />By 1987, two units at Hayden and three units at
<br />Craig were on line, The present combined use of
<br />water is estimated to be 13,000 acre-feet with
<br />ultimate depletions of 19,000 acre-feet,
<br />consisting of 13,000 acre-feet at Craig with zero
<br />discharge and 6,000 acre-feet at Hayden with no
<br />significant return flow,
<br />
<br />Colorado Ute-Southwest Project
<br />
<br />Colorado-Ute Electric Association planned
<br />construction of two 400-megawatt (MW) units in
<br />western Colorado, Plans to go forward have
<br />been delayed indefinitely, For purposes of this
<br />table, Reclamation has assumed that one unit
<br />will be constructed and on line by 2000 and the
<br />other unit will be on line in 2020,
<br />
<br />Utah
<br />
<br />Miscellaneous Additional Depletions
<br />
<br />Values used represent additional depletions that
<br />have developed since the Comprehensive
<br />Framework Study (1965 level) estimates were
<br />prepared, The Utah Division of Water
<br />Resources (DWR) provided these values and the
<br />projections to 2010,
<br />
<br />Bonneville Unit, Central Utsh Project
<br />
<br />Present depletions from the Bonneville Unit
<br />include reservoir evaporation, storage accrual,
<br />and irrigation uses from Currant Creek,
<br />Strawberry, Soldier Creek, and Starvation
<br />Reservoirs, Project storage which was accruing
<br />in Strawberry Reservoir was spilled into Soldier
<br />Creek Reservoir in 1983 because of high runoff
<br />conditions and prior storage rights ofthe
<br />Strawberry Valley Water Users in Strawberry
<br />Reservoir, Elevation limitations of reservoir
<br />water surface in Soldier Creek Reservoir further
<br />reduced the capability of storing water for
<br />project purposes, Net depletions to the Colorado
<br />River System in 1990 are estimated to be about
<br />56,000 acre-feet, Based upon the present
