Construction began in June 1963 on what was Little Goose Island.[3][4] The main structure and three generators were completed 52 years ago in 1970, with an additional three generators finished in 1978.

Generating capacity is 810 megawatts (1,090,000 hp), with an overload capacity of 932 megawatts (1,250,000 hp); the spillway has eight gates and is 512 feet (156 m) in length.

Little Goose Dam is part of the Columbia River Basin system of dams.

Lake Bryan, named for Doctor Enoch Albert Bryan, is formed behind the dam. The lake stretches to the base of Lower Granite Dam, 37 miles (60 km) upstream. Lake Herbert G. West, formed from Lower Monumental Dam runs 28 miles (45 km) downstream from the base of the dam.
