" '.,...."7 ~u, L Report of the Regional Director . 44. The Western Slope features would enable the average annual diversion of an estimated 69,200 acre-feet of project water. As a result of Eastern Slope storage to be provided by the project, about 14,900 acre-feet of water co,ud also be diverted annually by the Twin Lakes Company, which cannot now be diverted for lack of storage capacity. This would be in addi tion to its present average diversion of 38,000 acre-feet. Eastern Slope supply and power features . 45. In round figures, the major potential Eastern Slope project facilities include: 3 earth-fill dams, 60 miles of power canal ranging in capacity from 300 to 1,000 second-feet, 3 diversion dams, over 10 miles of diversion canals, 7 hydro- electric powerplants and switchyards, 3 small forebays and 2 afterbays, 9 substations, about 400 miles of transmission line, and a municipal water supply system. The latter system includes: 1 diversion dam, 15 miles of reservoir supply canal for irrigation replacement water, 3 pumping plants, 1 small regu~ating reservoir, 1 treatment plant, and about 175 miles of pipelines. Other structures and equipment would be re- quired for construction and operation such as one permanent camp, caretakers' residences and shops, warehouses, construc- tion camps, offices and laboratories, and a communications system. . 46. Imported and native water would be stored first in an enlarged Sugar Loaf Reservoir on the Lake Fork of the Arkansas River. Releases would flow about 20 miles 'lJPuth in the Elbert section of the Arkansas Power Cmal, then through the Elbert Hydroelectric Powerplant and into th e enlarged Twin Lakes Reservoir. The 10-mile Snowden Canal would di- vert additional Arkansas River water into the Twin Lakes Res- ervoir. From there, the water--increased by tributary in- terceptions and by the Wapaco diversion from the river--would flow south Some 40 miles in the Arkansas Power Canal and be returned to the main stream near Salida. Power would be gen- erated en route in the Granite, Wapaco, Princeton, Johnson, and Salida Hydroelectric Powerplants. Forebays would be pro- vided above the Princeton, Johnson, and Salida plants. The existing Clear Creek Reservoir (capacity about 11,400 acre- feet) would be adapted for use as an afterbay for the Granite Powerplant. An after bay would be provided on the Arkansas River for the "alida plant. Near Salida and Canon City some water might be diverted for irrigation. The remain- der would continue down the river to the potential Pueblo R 15
