The Mahoning Creek Dam, operated and managed by the U.S. Army Corps of Engineers Pittsburgh District, releases water downstream in New Bethlehem, Pennsylvania, March 19, 2025. The dam began operating in 1941 and cost approximately $6 million to build. Since its construction, the dam has prevented more than $812 million in flood damages. A small team of a natural resource managers, one full-time park ranger and three maintenance workers maintain Mahoning Creek Dam. The aging dam needs regular attention and maintenance and is due for a concrete facelift in the coming years. The reservoir and surrounding federal lands encompass more than 2,900 acres, but much of it is leased to the Pennsylvania Fish and Boat Commission and Armstrong County for various recreational purposes, including camping, boat launches, parks, fishing and hunting.
