Horse Mesa Dam and Apache Lake
Built in the mid-1920s, Horse Mesa Dam helped more than double SRP's hydropower generating capacity. It forms Apache Lake, a remote escape for outdoor enthusiasts.
History of Horse Mesa Dam and Apache Lake
Horse Mesa Dam was part of the power expansion program developed by General Superintendent Charles C. Cragin in the early 1920s. The program called for the construction of three hydroelectric dams on the lower Salt River along with a power transmission system.
Horse Mesa Dam was the second of three hydroelectric dams built at the time. Mormon Flat Dam was the first and Stewart Mountain Dam was the third.
Located between Mormon Flat and Roosevelt dams, the concrete thin-arch structure dam was completed in 1927. It stood 305 feet high and 660 feet long. It was named for nearby Horse Mesa, where thieves sometimes hid stolen herds.
The three dams more than doubled SRP's hydropower generating capacity and improved the control of irrigation releases.*
Today, Horse Mesa Dam has three conventional hydroelectric generating units rated at a total of 32,000 kW. It also has one pumped storage hydroelectric unit that was added in 1972, which is rated at 97,000 kW.
The dam forms Apache Lake, an uncrowded escape for fishing, boating and more.
