Completed in 1937, the dam serves primarily for flood risk reduction, but also supports fish and wildlife pond and recreational purposes. With a hydraulic height of 97 feet and a structural height of 113 feet, the dam holds a normal storage capacity of 13,500 acre-feet and covers a surface area of 2,600 acres.
The US Army Corps of Engineers (USACE) oversees the operation, maintenance, and risk management of Pleasant Hill Dam. The dam has been identified with a moderate to high risk of failure, particularly in areas prone to erosion and seepage. To mitigate these risks, the USACE has implemented various risk management measures, including ongoing maintenance programs, regular inspections, and the development of an Interim Risk Reduction Measure plan. These efforts aim to reduce the consequences of a potential failure or overtopping event, ensuring the safety of nearby communities such as Perrysville, Greer, Brinkhaven, Walhonding, and Loudonville.
Despite the high hazard potential associated with Pleasant Hill Dam, proactive risk management strategies are in place to address potential issues and enhance emergency preparedness. With a focus on continuous monitoring, maintenance, and improvement of emergency action plans, the USACE is dedicated to safeguarding the surrounding areas from the impacts of dam failure and ensuring the dam's resilience in the face of changing climate conditions.
