It was named for two brothers, Charles P. Hoover and Clarence B. Hoover, to honor their careers with the City of Columbus Waterworks. en.wikipedia.org/wiki/Hoover_Reservoir The Alum Creek Lake reservoir was built in 1974, covers 123 sq mi (318.57 km²) and has a maximum capacity of 134,815 acre feet (166,292,000 m3). Alum Creek Dam which was constructed between 1970 and 1974 is located on Alum Creek, a tributary of Big Walnut Creek, which drains into the Scioto River. The dam is a rolled earth-fill embankment 10,000 ft (3,000 m) in length with a maximum height of 93 ft (28 m) The spillway is located high on the right abutment with the raceway dropping off in front of it to the stilling basin below. Control is provided by three 34 by 25 ft (7.6 m) tainter gates supported by 8 ft (2.4 m) wide concrete piers resting on concrete ogee sections.
