Mahoning Creek Dam

Mahoning Creek Dam is a concrete gravity structure in Armstrong County that spans across the waterway and creates a large reservoir for the area. The construction holds back water primarily for flood control and water management purposes.

The structure was built in 1941 by the United States Army Corps of Engineers as part of a regional flood control program. In 2012, it received modifications to generate electricity and support local energy needs.

The dam and its surrounding parkland provide opportunities for fishing, boating, camping, and hiking activities throughout the recreational seasons.

The site sits between two township areas and is accessible via local roads that wind through wooded surroundings. Visitors should be prepared for changing weather and wear comfortable shoes when exploring the area around the structure.

The wall relies on the weight of concrete itself to resist water pressure, requiring no cables or internal supports to stay in place. This straightforward design approach has proven effective in water engineering for more than a century.
