<br />Location:

<br />Upper Colorado River Basin In Montrose and San Miguel
<br />Counties of Southwestern Colorado.

<br />Sponsors:
<br />
<br />San Miguel Water Conservancy District and Southwest
<br />Water Conservation District.
<br />
<br />Primary Purpose of the Project:
<br />Irrigation, Municipal and Industrial Water Supply.
<br />
<br />Secondary Benefits:
<br />
<br />Recreation, Fish and Wildi[fe and Flood Control.
<br />
<br />History and Background:
<br />
<br />Planning for the San Miguel Project has been carried out
<br />at various times since the early 1900's.
<br />
<br />When the project was authorized for construction In 1968,
<br />it was contemplated to serve approximately 39,000 acres
<br />f. and provide 44,000 acre-feet/year of municipal and In-
<br />. dustrial water.
<br />~>
<br />Advanced pla'll'ing studies began:' in 1971 and wer~
<br />suspended In 1'9t,.bY the salinity impacts moratoriurri\ .
<br />and as a result, a-$significant portion of the irrigation
<br />service area was deleted trom the project. Municipal and
<br />industrial water demand projections have also been
<br />significantly reduced.
<br />
<br />To date, a feasible plan (benefits exceeding costs) has not
<br />been identified. Economic problems associated with the
<br />alternative plans .Include high construction cost of
<br />highway relocations, high operation and maintenance
<br />costs including power costs for pumping, high distribu-
<br />tion costs due to dispersed irrigation service area, and
<br />limited repayment capability.
<br />
<br />The Water and Power Resources Service has met several
<br />
<br />times with the San Miguel Water Conservancy District
<br />during the past few month~ to attemptto identify a feasible
<br />plan. These attempts h<jye been.unsuccessful. The future
<br />of the San Miguel projelOt is presently uncertain. .
<br />
<br />Although a feasible pian cannot be ide~i.l3d, the data
<br />presented in this project summary repres " those alter-
<br />native plans that are most nearly feasible. 'c"c .:'
