Show be supplied by feeder canals from Dallas and Cow Creeks, respectively. Part of the water released from Ridgway Reservoir would be pumped by hydraulically driven turbines a vertical distance of 495 feet to the lower lands on Log Hill Mesa. The remainder would propel the turbines and then supply existing and project rights downstream. The higher lands on Log Hill Mesa would be served by gravity releases from the Dallas Divide Reservoir. The project would provide irrigation water for 23,620 acres, including 14,900 acres that are not now irrigated. It would provide 15,000 acre-feet annually for municipal and industrial use in the Uncompahgre Valley. The municipal water would be distributed by the Tri-County Water Conservation District.

Dolores Project The Dolores Project would develop water of the Dolores River for irrigation, municipal and industrial use, recreation, and fish and wildlife conservation and flood control. Primary storage would be provided by McPhee Reservoir on the Dolores River. All project water would be released from the reservoir to the potential Dove Creek Canal which, with other project branch canals and existing systems, would deliver the water to the land. The offstream Cahone, Ruin Canyon, and Monument Creek Reservoirs would be constructed as part of the distribution system to facilitate water regulation. The project would provide irrigation water for 61,000 acres, including 32,340 acres that are not irrigated at present. About 1,500 acres of the land is in Indian ownership. About 6,100 acre-feet of municipal and industrial water annually would be provided for the communities of Dove Creek and Cortez.
