Shenango River Lake is one of 16 flood-control projects operated by the U.S. Army Corps of Engineers Pittsburgh District. The project mitigates flooding in the Shenango River Valley as well as the Beaver and upper Ohio rivers. Since its completion in 1965, Shenango Dam has prevented more than $252 million in flood damages. (U.S. Army Corps of Engineers Pittsburgh District photo by Michel Sauret)
