Bureau of Reclamation posted
Located east of Phoenix, Mormon Flat Dam impounds Canyon Lake, a favorite recreation area for boating and fishing. It was the first dam constructed under Salt River Project’s hydroelectric expansion program in the 1920s. Mormon Flat Dam was named after nearby Mormon Flat, a place where pioneers from Utah stopped to camp on their way to the valley

"The Mormon Flat Dam was completed in 1926, the first of three dams along the lower Salt River, between Theodore Roosevelt Lake and Phoenix, two of which have powerhouses with reversible turbines, enabling pumped storage functions. The Mormon Flat hydroelectric plant has a conventional turbine, producing 10 megawatts, and a reversible unit that was installed in 1971, adding another 50 megawatts to the plant’s generating capacity, and enabling the plant to pump water backwards through the Salt River Project system, a network of several hydropower plants and reservoirs that provide electricity to the Phoenix region."

"Mormon Flat Dam, a 224-foot high concrete thin-arch structure,...creates a 57,852 acre-foot reservoir.
"In 1938, Reclamation completed construction of a new gate structure and a concrete-lined spillway discharge channel, and installed two 50-foot-square stoney regulating gates, hoists, motors, two 25-kilovolt-ampere gasoline-engine driven generators, and a new road to the powerhouse."
