Authorized by the Flood Control Act of 1962, the dam was completed in 1971 and provides flood protection for the French Creek Valley, and to a lesser degree, the Allegheny River below Franklin, Pa. The reservoir has the capability of storing the equivalent runoff of 4.08 inches of precipitation from its 222 square mile watershed. The flood prevention benefits provided by the project since completion are estimated to be approximately $108 million.
