The C.C. Cragin project consists of a number of facilities, including a dam and reservoir, diversion tunnel and pump shaft, pumping plant, priming reservoir, pipeline, electrical transmission line, and a generating plant. Water is pumped from the reservoir to the East Verde River via the pumping plant and related facilities. SRP pumps water at a maximum rate of 35 cubic feet per second from the reservoir during the summer and fall for deliveries to SRP shareholders, the Town of Payson, and other Northern Gila County communities. The project is located in the Coconino and Tonto national forests.
SRP acquired Blue Ridge Reservoir from Phelps Dodge Corp. in February 2005 as part of the Gila River Indian Water Rights Settlement approved by the Arizona Water Settlement Act. The reservoir and dam were renamed C.C. Cragin at that time as a tribute to an early SRP hydrologic engineer. The settlement act resolved various water rights issues and allowed for the transfer of the reservoir to SRP from Phelps Dodge, which built Cragin Dam in 1965 for the purpose of collecting water to deliver to the Verde River as a water-exchange settlement with SRP. In addition to satisfying obligations to the Gila River Indian Community, Cragin is used to supplement SRP shareholders' water supply and to assist in improving the water supply situation in Payson and northern Gila County in accordance with the Arizona Water Settlements Act. SRP transferred ownership of the Cragin facilities to the U.S. Bureau of Reclamation, but continues to serve as operator of the system.
