Hoover Dam dams the Big Walnut Creek, forming the Hoover Memorial Reservoir, which holds 20.8 billion gallons of water. Construction began during 1953; the dam was dedicated in 1955 and officially opened in 1958. It was named for brothers Charles P. Hoover and Clarence B. Hoover in honor of their careers with the City of Columbus Waterworks.
