Hoover Dam, in Blendon Township, near Westerville, Ohio, dams Big Walnut Creek to form the Hoover Memorial Reservoir. This reservoir is a major water source for the city of Columbus, Ohio. It holds 20.8 billion US gallons (79,000,000 m³) of water and has a surface area of 3,272 acres (13.24 km²), or about five square miles. Construction began during 1953 due to the increased water demand of post-war Columbus. The project was completed and dedicated in 1955 and the dam officially opened in 1958. It was named for two brothers, Charles P. Hoover and Clarence B. Hoover, to honor their careers with the City of Columbus Waterworks.^[2][3]
