Hoover Dam (Ohio)

Hoover Dam, in Blendon Township, Franklin County, Ohio, near Westerville, dams Big Walnut Creek to form the Hoover Memorial Reservoir. 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]

The dam's reservoir is a major water source for the city of Columbus. 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. The dam is 2,583 ft (787 m) long, including 680 ft (210 m) of spillway.^[4] It was constructed from 180,000 cubic feet (5,100 m³) of concrete and 591,500 cubic feet (16,750 m³) of earth.

The dam reaches a maximum height of 94 feet (29 m) above the stream bed, and is 911 feet (278 m) above sea level at its peak elevation. The uncontrolled spillway reaches a peak elevation of 890 feet (270 m) above sea level.^{[citation needed]}
