Built in 1909 for recreational purposes, this dam stands at a height of 27 feet and has a storage capacity of 133 acre-feet. It spans 410 feet across Harmon Creek and covers an area of 10 acres, serving as a popular recreational spot for local residents and visitors alike.
Despite its age, Dinsmore No 2 has been well-maintained and regularly inspected by the Pennsylvania Department of Environmental Protection to ensure its safety and structural integrity. With a high hazard potential, the dam poses a significant risk in the event of a failure, making it essential for proper risk assessment and management measures to be in place. The latest inspection in March 2021 deemed the dam's condition as satisfactory, but ongoing monitoring and emergency preparedness are crucial to mitigate any potential risks associated with its operation.
As an integral part of the water infrastructure in Washington County, Pennsylvania, Dinsmore No 2 serves not only as a recreational destination but also as a key component in the overall water resource management system. With proper regulatory oversight and maintenance practices in place, this dam continues to play a vital role in providing water storage, flood control, and recreational opportunities for the surrounding community.
