Hoover Dam

This dam blocks the Big Walnut Creek forming the Hoover Memorial Reservoir. The reservoir creates a water source for the city of Columbus, and also provides much recreation. Several parks line the reservoir, where wildlife is abundant. Fishing and boating (with a 6hp restriction) are permitted on the reservoir, with several boat ramps and fishing access areas. The water in the reservoir remains the coldest among the other two nearby reservoirs. It is typically in the high 60's to low 70's (f) in the middle of summer.
