<br />period being 285,200 acre-feet in 1988, There
<br />has been no expansion of diversions through the
<br />Adams Tunnel.
<br />
<br />Windy Gap is the newest feature of the
<br />Colorado-Big Thompson Project, Windy Gap
<br />pumps water from the Fraser-Colorado River
<br />confluence up to Granby Reservoir for
<br />subsequent delivery to the east slope through
<br />the Adams Tunnel. The Windy Gap Project
<br />began operation in 1987, In 1988, Windy Gap
<br />pumped 19,863 acre-feet, and in 1990, it pumped
<br />14,519 acre-feet, Operation of Windy Gap is
<br />expected to increase diversions by the
<br />Colorado-Big Thompson Project by
<br />54,000 acre-feet per year, The water will be
<br />used for municipal and industrial purposes by
<br />the cities of Longmont, Loveland, Estes Park,
<br />and the Platte River Power Authority, Values
<br />were supplied by the Colorado Water
<br />Conservation Board in consultation with the
<br />Northern Colorado Water Conservancy District,
<br />
<br />Miscellaneous Exports
<br />
<br />Miscellaneous exports by 12 small trans-
<br />mountain diversion ditches have increased by
<br />5,417 acre-feet since 1965. In 1965, the
<br />normalized diversions from these 12 ditches
<br />were 19,880 acre-feet and in 1990 the
<br />normalized diversions were 20,297 acre-feet,
<br />The diversions between 1981 and 1990 are
<br />summarized as follows:

<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 for a total depletion of
<br />154,800 acre-feet per year for irrigation and
<br />M&I use with 120,700 acre-feet in Colorado and
<br />34,100 acre-feet in New Mexico, Depletions will
<br />not begin until the late 1990's when Ridges
<br />Basin Reservoir is completed, Due to flow
<br />requirements for endangered fish, the Fish and
<br />Wildlife'Service (FWS) has recommended
<br />limiting the total depletion of the project to
<br />5'7,100 acre-feet (37,700 acre-feet in Colorado
<br />and 19,400 acre-feet in New Mexico), Additional
<br />depletions will be contingent upon future
<br />approvals by the FWS,
<br />
<br />Bostwick Park Project
<br />
<br />Construction of Silver Jack Dam commepced in
<br />late 1966 and was completed in 1971. Project
<br />water became available beginning in 1971, and
<br />all 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 of
<br />water used for agricultural, municipal, and
<br />industrial purposes, Estimated depletions are
<br />5,100 acre-feet for irrigation, 10,400 acre-feet for
<br />M&I 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 the
<br />combination of reservoir evaporation, irrigation
<br />use, and M&I use will deplete about 7,000 acre-
<br />feet by 1990, 12,000 acre-feet by 2000, and
<br />17,100 acre-feet by 2010,
<br />
<br />Dolores Project
<br />
<br />A Feasibility Report was prepared in 1963, and
<br />the project was authorized by Public Law 90-537
