<br />Independence Pass, Pueblo, and Colorado
<br />Springs Expansions and Englewood
<br />
<br />Projected values for these exports were supplied
<br />by the Colorado Water Conservation Board.
<br />
<br />Frylngpan-Arkansas Project
<br />
<br />DiversiQns through Boustead Tunnel began in
<br />1971. The average annual diversion during the
<br />1972-76 period was 33,000 acre-feet per year;
<br />the 1977-81 period was 44,000 acre-feet per
<br />year; and the 1982-85 period was 87,000 acre-
<br />feet per year. The diversion in 1983 was
<br />90,800 acre-feet. The operating principles for
<br />the project state that diversions will not exceed
<br />120,000 acre-feet in any year and will not exceed
<br />a total aggregate of2,352,800 acre-feet in any
<br />consecutive 34-year period. The latter
<br />requirement would mean a long-time average
<br />diversion of 69,200 acre-feet. Since the
<br />historical (1971-83) average diversion has been
<br />much less than this, it is likely that in the
<br />coming decade or so annual diversions will be
<br />much higher than 69,200 acre-feet (provided
<br />that water is available for diversion) to bring the
<br />historical average back up.
<br />
<br />Windy Gap
<br />
<br />Windy Gap Dam has been completed and is
<br />in operation. Diversions in 1987 totaled
<br />2,000 acre-feet. Facilities of the Colorado-Big
<br />Thompson Project are used to divert up to
<br />54,000 acre-feet per year for domestic use by the
<br />cities ofLongmont, Loveland, Estes Park,
<br />Greeley, and the Platte River Power Authority.
<br />High runoff since 1985 has resulted in no
<br />increase in diversions from Windy Gap. Values
<br />were supplied, by the Northern Colorado Water
<br />Conservancy District.
<br />
<br />Miscellaneous Exports
<br />
<br />Miscellaneous exports by 12 small trans-
<br />mountain diversion ditches have increased by
<br />3,000 acre-feet since 1965. In 1965, the
<br />normalized diversions from these 12 ditches
<br />were 19,880 acre-feet. The 1977-1986 average
<br />
<br />was 23,600 acre-feet. Values were supplied by
<br />the Colorado Water Conservation Board.
<br />
<br />Animas-La Plata Project
<br />
<br />Reclamation prepared a feasibility report in
<br />1962, and the project was authorized by Public
<br />Law 90-537, September 30, 1968. A definite
<br />plan report was approved in August 1980. The
<br />plan provides a total depletion of 154,800 acre-
<br />feet per year for irrigation and municipal and
<br />industrial use, with 120,700 acre-feet in
<br />Colorado and 34,100 acre-feet in New Mexico.
<br />Depletions will not begin until the late 1990's
<br />when Ridges Basin Reservoir is completed. Uses
<br />will build up rapidly as other project facilities
<br />are constructed.
<br />
<br />Bostwick Park Project
<br />
<br />Construction of Silver Jack Dam began in late
<br />1966 and was completed in 1971. Project water
<br />became available beginning in 1971, and all
<br />facilities were completed by 1974. Project
<br />depletions average 4,200 acre-feet annually.
<br />
<br />Dallas Creek Project
<br />
<br />The project was authorized by Public Law
<br />90-537 on September 30, 1968. A definite plan
<br />report was completed in November 1976 which
<br />indicated a total depletion of 17,100 acre-feet,
<br />with the water being used for agricultural and
<br />municipal and industrial purposes. Estimated
<br />depletions are 5,100 acre-feet forirrigation,
<br />10,400 acre-feet for municipal and industrial
<br />uses, and 1,600 acre-feet for reservoir
<br />evaporation. Initial storage began in 1987.
<br />Distribution facilities now exist for use of the
<br />project water. Reclamation estimates that
<br />the combination of reservoir evaporation,
<br />irrigation use, and municipal and industrial use
<br />will deplete about 7,000 acre-feet by 1990,
<br />12,000 acre-feet by 2000, and 17,100 acre-feet by
<br />2010.
