. . . """ .t'~... /"'" ~"1~') BASALT PROJEC'l' PLAN SELECTION AND ALTERNATIVES area would be diverted at the outlet of the Missouri Heights Reservoir and then siphoned across Roaring Fork River and used in the same manner as in Plan 3. Plans 5 through 11 These plans would add lands in the Carbondale area to those that would be irrigated under Plans 3 and 4. The total project irrigated area would thus be 20,489 acres as in the adopted plan (Plan 8), including 14,362 acres of full service land and 6,127 acres of supplemental serv- ice land. Plan 5 is essentially the same as the adopted plan except that the Missouri Heights Reservoir would not be utilized and the Basalt Conduit would have a larger capacity (275 second-feet) and ,muld be at a lower alignment. The Basalt Conduit would terminate on the drainage channel on which the Missouri Heights Reservoir is located but at a point 50 feet below the reservoir outlet. The Landis Canal would head at the terminus of the conduit. The Carbondale Canal and other facilities required for service to the Carbondale and Sopris areas would be the same as in the adopted plan. In Plan 6 the Basalt Conduit would be at the higher alignment as in the adopted plan. Its capacity would be 250 second-feet above a turnout for the Stockman's ditch and 195 second-feet from the turnout to the Missouri Heights Reservoir. The reservoir would be enlar~ed to a capac- ity of 6,600 acre-feet, compared with 21,500 acre-feet in the adopted plan. Distribution facilities for the Cattle Creek area would be the same as in the adopted plan. The Stockman's ditch turnout on the Basalt Canal would be at the same general location as in Plan 3. The drop from the turnout to the siphon across Roaring Fork would be greater than in Plan 3, however. The Stockman's ditch would be enlarged and extended to serve project lands in the Sopris area. The Carbondale Canal with a capacity of 30 second-feet would extend southwest from the terminus of the Stockman's ditch extension, conveying water to landS in the Car- bondale area. Plan 7 is identical to Plan 6 except that the Missouri Heights Res- ervoir would be enlarged to a capacity of 14,500 acre-feet, thus permit- ting the capacity of the Basalt Conduit to be reduced to 155 second-feet above the Stockman's turnout and 100 second-feet below the turnout. Plan 8 is the adopted plan described and analyzed in detail in pre- vious chapters of this report. Plan 9 is the same as the adopted plan except that the Basalt Con- duit would be constructed at the lower and less costly location and the Missouri Heights Pumping Plant with a capacity of 100 second-feet and a 43
