The concrete gravity dam was constructed in 1941 by the United States Army Corps of Engineers, with a height of 162 feet, and a length of 926 feet at its crest.[1]
In 2012, the dam was retrofitted for hydroelectric power generation which produces about 6 MW.[3]
The riverine reservoir it creates, Mahoning Creek Lake, has a normal water surface of 280 acres (110 ha), a maximum capacity of 94,000 acre-feet (116,000,000 m3), and a normal capacity of 9,550 acre-feet (11,780,000 m3).[4]
Recreation opportunities here include boating, fishing, camping, and hiking,[5] as well the facilities of the state-run Mahoning Creek Lake Park.
