<br />Present and Future Development
<br />
<br />the Adams Tunnel averaged 234,950 acre-feet between 1984 and 1993 with the maximum
<br />diversion during that lO-year period being 285,200 acre-feet in 1985. There has been no
<br />expansion of diversions through the Alva B. Adams Tunnel.
<br />
<br />Windy Gap is the newest feature of the Colorado-Big Thompson Project. Windy Gap pumps
<br />water from the Fraser-Colorado River confluence up to Granby Reservoir for subsequent delivery
<br />to the east slope through the AlvaB. Adams Tunnel. The Windy Gap Project began operation in
<br />1987. In 1988, Windy Gap pumped 19,863 acre-feet, and in 1993 it pumped 21,740 acre-feet.
<br />Operation of Windy Gap is expected to increase diversions by the Colorado-Big Thompson Project
<br />by 54,000 acre-feet per year. The water will be used for M&I purposes by the cities of Longmont,
<br />Loveland, Estes Park, and the Platte River Power Authority. Values were supplied by the
<br />Colorado Water Conservation Board in consultation with the Northern Colorado Water
<br />Conservation District.
<br />
<br />Miscellaneous Exports-Miscellaneous exports by 12 small transmountain diversion ditches have
<br />increased by 5,417 acre-feet since 1965. In 1965, the normalized diversions from these 12 ditches
<br />were 19,880 acre-feet, and in i 990 the diversions were 24,844 acre-feet. The diversions between
<br />1984 and 1993 are summarized on the following page. Miscellaneous exports include the Grand
<br />River Ditch, Eureka Ditch, Berthoud Pass Ditch, Vidler Tunnel, Larkspur Ditch, Tarbell Ditch,
<br />Tabor Ditch, Treasure Pass Ditch, Don La Font Ditches I and 2, Williams Creek-Squaw Pass
<br />Ditch, Pine River-Weminuche Pass Ditch, and the Weminuche Pass Ditch.
<br />
<br />Animas-La Plata Project-Reclamation prepared a feasibility report in 1962, and the project was
<br />authorized by Public Law 90-537 on September 30, 1968. A definite plan report was approved in
<br />August 1980. A supplement to the environmental statement was completed in April 1996. The
<br />plan provides for irrigation, municipal, and industrial use in the states of Colorado and
<br />New Mexico.
<br />
<br />Bostwick Park Project-Construction of Silver Jack Dam commenced in late 1966 and was
<br />completed in 1971. Project water became available beginning in 1971, and all facilities were
<br />completed by 1974. Project depletions average.4,200 acre-feet annually.
<br />
<br />Dallas Creek Project-The project was authorized by Public Law 90-537 on September 30, 1968.
<br />A definite plan report was completed in November 1976, which indicated a total depletion of
<br />17,100 acre-feet of water used for agricultural, municipal, and industrial purposes. Estimated
<br />depletions are 5,100 acre-feet for irrigation, 10,400 acre-feet for municipal and industrial uses, and
<br />1,600 acre-feet for reservoir evaporation. Initial storage began in 1987. Distribution facilities now
<br />exist for use of the project water. .
<br />
<br />Dolores Project-A feasibility report was prepared in 1963, and the project was authorized by
<br />Public Law 90-537 on September 30, 1968. A definite plan report was completed in April 1977
<br />with modifications to the original plan to meet Native American requirements. Ultimate total
<br />project depletions are estimated to be 80,900 acre-feet annually. Average annual consumptive use
<br />will be 70,250 acre-feet for irrigation, 4,350 acre-feet for municipal and industrial use, and
<br />6,300 acre-feet for evaporation.
