Congress authorized the Cheatham Lock and Dam Project in 1946 as a navigation unit of a comprehensive plan of development for the Cumberland River Basin. The dam is located in Cheatham County, Tenn., on the Cumberland River at mile 148.7 about nine miles downstream of Ashland City.
The original purpose of this water resources development project was to replace three smaller, aging locks built at the turn of the century: Lock A at Cumberland River Mile 150.6, Lock 1 at Mile 188.4, and Lock 2 at Mile 201.0. The ideal construction site was about nine miles downstream of Ashland City at River Mile 148.7, just 42 miles below Nashville.
In 1952, Congress added authorization for the production of hydroelectric power as a project function. The lock, dam, and power plant were designed by the U.S. Army Corps of Engineers and built by private contractors under Corps supervision. Construction started in April 1950, and the lock was opened to navigation in December 1952. The project became fully operational with the completion of the third generating unit in the power plant in November 1960.
The hydropower plant features three Westinghouse generators. Each generator produces 12 megawatts, 13,800 volts, 60 cycles, with a total potential output of 36 megawatts capable of powering 23, 400 residential homes at maximum output, with an annual average capability of powering 15,000 residential homes
Cheatham Lake covers 7,450 acres and has 320 miles of shoreline. The lake is a "run-of-the-river" type that operates basically on normal stream flow. The Corps uses as much of the inflow as practicable for hydropower generation. The dam was not constructed to provide a designated capacity for regulating floodwaters. Therefore, during periods of heavy rainfall and high stream flow, the spillway gates are opened to pass waters in excess of the capacity of hydropower turbines.
