. . . ,." /' t... ~~ t:. ~1'.J, ~J BASALT PROJECT PLAN SELECTION AND ALTERNATIVES or elimination of the reservoir whi~h in turn would require a greater conduit capacity to meet pem< irrigation demands. One plan would use the higher conduit location but would eliminate the upper 9.8-mile sec- tion of the conduit snd would pump to the remaining section. Enlarge- ment of the Missouri Heights Reservoir is included in at least one plan for each project acreage and eliminated in one plan for each of the three smaller acreages. Plans 1 and 2 Plans 1 and 2 would provide irrigation water only for lands in the Cattle Creek area. Both of these plans would provide water for 17.655 acres in that area. including 12.667 acres of full service land and 4.988 acres of supplemental service land. The Cattle Creek area landS served would be the soone as in the adopted plan. Under Plan 1 the Basalt Conduit would be built with a steeper hydrau- lic gradient so that it could not supply the Missouri Heights Reservoir. The canal would extend from the outlet of Ruedi Dam to a point about one mile northwest of Basalt. Colo. The Landis Canal would extend from the outlet of the Basalt Conduit to a point about 1 1/2 miles west of Landis Creek. The Spring Valley lateral ;Tould divert from the Landis Canal as in the adopted plan. The Basalt Conduit and the Landis Canal above Cat- tle Creek would have capacities of 220 second-feet. Beyond that point the Landis Canal would have a capacity of 140 second-feet to Landis Creek and thence 50 second-feet to its end. Plan 2 would serve the Cattle Creek area by the same means as the adopted plan except that the Basalt Conduit would have a capacity of only 100 second-feet and the Missouri Heights Reservoir would be enlarged to a capacity of only 14.500 acre-feet. Plans 3 and 4 Plans 3 and 4 would provide irrifation water to Cattle Creek lands and in addition would serve 885 acres in the Sopris area, including 485 acres of full service land and lfOO acres of supplemental service land. Plan 3 is the same as Plan 1 except that the capacity of the Basalt Conduit would be increased to 245 second-feet and a drop structure and siphon taking off at the end of the conduit would deliver 25 second-feet of water across Roaring Fork River to the existing Stockman's ditch which would be enlarged and extended to serve the lands in the Sopris area. Plan 4 is the same as Plan 2 except that the capacity of the Basalt Conduit would be increased to 130 second-feet and water for the Sopris lf2
