<br />San Miguel Project
<br />
<br />March 1980
<br />
<br />
<br />LOCATION
<br />
<br />The San Miguel Project is located in the Upper
<br />Colorado River Basin in Montrose and San Miguel
<br />Counties of southwestern Colorado.
<br />
<br />e
<br />
<br />PURPOSE
<br />
<br />',The project Would be a muntiple-purpose water re-
<br />source development that would regulate flows of the
<br />San Miguel River for irrigation, municipal and in-
<br />dustrial use, fish and wildlife, recreation, and
<br />flood control.
<br />
<br />~
<br />
<br />The San Miguel Project was authorized fo~ construc-
<br />tion by the Colorado River Basin Act of September 30,
<br />1968 (Public !4W 90-537) as a participating project
<br />under the Colorado River Storage Project Act of
<br />April 11, 1956 (P.L. 84-485). The project is in the
<br />advanced planning stage.
<br />
<br />The FY-80 appropriations include $460,000, and the
<br />President's proposed budget for FY-81 includes
<br />$100,000 to continue advanced planning.
<br />~lj
<br />
<br />The project would develop 14,000 acre-feet of water
<br />. to irrigate 12,400,.acrres of aupplemental service
<br />land, and 14,000 acre-feet of water to irrigate
<br />6,600 acres of full service land. An additional
<br />21,000 acre-feet of water would be acquired by ex-
<br />change from an existing water supply stored in
<br />Gurley, Cone, and Lilylands Reservoirs. The muni-
<br />cipal and industrial water supply would total 14,000
<br />acre-feet.
<br />
<br />e
<br />
<br />Flows of the San Miguel River would be regulated by
<br />Saltado Reservoir or an off-stream reservoir, and
<br />releases ~ould be made for municipal and industrial
<br />users along the river. Municipal and industrial
<br />water for Wrights Mesa would be. provided by exchange

<br />from the existing Gurley Rcservoir. Irrigation
<br />water for Wrights Mcsa would be released into a
<br />9-mile-long pipeline that would follow the river
<br />downstream. At the end of the pipeline, a pumping
<br />plant would lift water onto Wrights Mesa. Irriga-
<br />tion water for Wrights Mcsa, East Lilylands, and
<br />Dry Creek Basin would be conveyed through the pro-
<br />. posed Basin Canal. Sprinkler irrigation would be
<br />used on all project lands.
