the ultimate yield of contracted water of 49,000 acre-feet in 2000.
Depletions were computed assuming 100 percent consumption of industrial water
and 40 percent consumption of water delivered to municipal and domestic users.
Ruedi water would go primarily to the oil shale industry. Present estimates
suggest that there will be no significant use of Ruedi water until 2000;
therefore, the depletion values have been set back 20 years, and a value of
16.000 acre-feet is shown for the year 2010.

s. Blue Mesa Contracts

The Upper Colorado Regional Office of the Bureau of Reclamation
has determined that up to 10,000 acre-feet of water can be contracted for out
of Blue Mesa Reservoir for industrial purposes. It has been assumed that this
water will be contracted by 2000 and that it will be 100 percent consumed.

t. Oil Shale

projections of water depletions for oil shale development
contain a high degree of uncertainty. values shown in Progress Report No. 12
were provided by the Colorado Water Conservation Board. for the present
table, Reclamation has chosen to assume that development will be deferred by
one decade, so all depletion values have been postponed 10 years. These
values do not include water contracted out of Ruedi Reservoir for the oil
shale industry.

u. Rock Creek, Bluestone, and Green Mountain Sales

These projects and depletion values have been added to the
table at the suggestion of the Colorado River Water Conservation District.
Rock Creek is located on the Upper Colorado River near Kremmling. It is a
transmountain exchange for municipal and industrial uses. Bluestone is
located near DeBeque and will be used for industrial and oil shale uses. Sale
of water out of Green Mountain Reservoir will be used for augmenting water
rights, for irrigation, and at ski areas.

v. Craig-Hayden Powerplants

In 1985, two units at Hayden and three units at Craig were
on line. Present use of water is estimated to be about 17,000 acre-feet.

w. Colorado Ute-Southwest Project

Colorado-Ute Electric Association is planning two 400-MW units
in western Colorado. four years ago, start-up dates of 19B7 and 1989 were
projected, but recent discussions with association officials indicate that
plans to go forward have been delayed indefinitely. For purposes of this
table, Reclamation has assumed that one unit will be constructed and on line
by 2000 depleting 5,000 acre-feet of water, and the other unit will be on line
in 2020, making a total depletion of 9,000 acre-feet.
