Lucky Peak Dam is a rolled earth and gravel fill embankment dam in the western United States, located on the Boise River in southwestern Idaho.

Most of the federal dams in southern Idaho, including the others on the Boise River, were built by the Bureau of Reclamation, not the Corps of Engineers.

The Idaho Power Company, a private utility, built multiple hydroelectric dams on the Snake River.

Located along State Highway 21, ten miles (16 km) upstream from the city of Boise, it was built without hydroelectric power generation.

Construction of the powerhouse began in 1984 and it became operational in 1988, generating electricity primarily for Seattle City Light.
