Canyon Lake. Completed in 1930, it was the last of the reservoirs to be built on the Salt River. It is somewhat larger than Canyon but smaller than the others, having a surface area of when full, holding . The dam is equipped with hydroelectric generators. Verde River reservoirs and other dams After completion of the four dams on the Salt River, SRP turned to the smaller Verde River for further expansion of the project. Like the reservoirs on the Salt, the Verde reservoirs are used for recreational purposes as well as water storage and flood control. Bartlett Lake The first of the lakes on the Verde River was created with the construction of the Bartlett Dam, finishing in 1939. At 308.5 feet (94 m) tall, the multiple-arch dam is lacking in hydroelectric generating capabilities, unlike most dams on the Salt River. Bartlett Lake, with of surface area at capacity, is larger than all the Salt River reservoirs save Roosevelt. When full the lake can hold of water. Horseshoe Lake Horseshoe Lake is formed by Horseshoe Dam and was finished in 1946, upstream from Lake Bartlett. Unlike the other dams built to this point, the construction was done by the Phelps Dodge Corporation as part of a water exchange agreement. In 1949, the city of Phoenix funded the construction of spillway gates for the dam in exchange for water rights for city users. Like Bartlett, this dam does not have hydroelectric generating capabilities. At in surface area when full it is slightly larger than Bartlett but has a smaller total capacity, holding only at maximum. C.C. Cragin Dam and Reservoir Phelps Dodge, Inc., a large mining company in Arizona, constructed the Blue Ridge Dam (now named C.C. Cragin) in 1965 to help meet its water needs. A water exchange agreement penned three years earlier promised the facilities to SRP, and in 2005 SRP took possession of the dam and water production facilities. Located on the Mogollon Rim, C.C. Cragin is not on the Salt or Verde rivers but is a part of the general watershed covered in the SRP area. The small lake has a storage capacity of only of water and is used to augment the water supply for the Gila River Indian Community, northern Gila County and the town of Payson. Granite Reef Dam The Granite Reef Diversion Dam, constructed near the confluence of the Salt and Verde
