Pymatuning is a state-regulated dam located in Crawford, Pennsylvania, along the Shenango River. Completed in 1933, this earth dam stands at 50 feet high and stretches 2400 feet in length, with a storage capacity of 445,000 acre-feet. Its primary purpose is flood risk reduction, but it also serves recreational purposes due to its surface area of 14,528 acres.

Despite its fair condition assessment and high hazard potential, Pymatuning has been modified structurally in 2010 to enhance its safety and efficiency. The dam is under the jurisdiction of the Pennsylvania Department of Environmental Protection, ensuring its regular inspection, permitting, and enforcement to meet regulatory standards. Managed by the state, Pymatuning plays a crucial role in protecting the surrounding community from flood risks while providing recreational opportunities for visitors to enjoy. Water resource and climate enthusiasts can appreciate the engineering marvel and environmental significance of this vital infrastructure in Pennsylvania.
