11. Clayhorse Site Alternative

::;~;3;
. .~--:

'.

Thi.s alternative would have a Clayhorse Dam ano Reservoir"with

the dam located on the San Higuel River 5.9 miles downstream of the

bridge at the bottom of Norwood Hill on Highway 145. Clayhorse

Reservoir "lOuld back water up the canyon 3.6 miles, and would have

a maximum ,mter surface of 367 acres. There would be no rf,locations,

but a 4.6-mile access road would have to be built up the canyon, an

extension of the current road that runs along the bottom of San Miguel

Canyon below Horsefly Creek. Approximately 5.4 miles of this existing

road would be improved.

Project water would be pumped directly to Wright's Mesa, a

vertical lift of 950 feet. The water would enter the head of Basin

Canal at a point 2.5 miles east of Norwood. llasin Canal would in turn

carry the water across Wright's Mesa and on to Dry. Creek Basin. Water

developed~from the existing system would be consolidated with the

water developed by the Clayhorse facilities to form the overall San

.
Miguel Project. Gurley Ditch would be lined to prevent water seepage.

The San Miguel Project, under this alternative, would provide

irrigation water for 12,,700 acres of supplemental and 7,060 acres of

full service land. Buried pipe laterals would be constructed to deliver

the irrigation water to project land, where it ,would be spread by means

of sprinkler systems. Municipal and industrial water would total 14,000

acre-feet: 12,000 acre-feet for the proposed Colorado-Ute Electric

Association's powerplant and 2,000 acre-feet for domestic use on Wright's
.

Mesa.
