The dam, standing at a height of 7 feet with a hydraulic height of 5.7 feet, impounds Nonacoicus Brook to create a reservoir with a storage capacity of 270 acre-feet. With a surface area of 28.4 acres and a drainage area of 15.8 square miles, the dam serves as a popular spot for outdoor activities and wildlife habitat in Middlesex County.
Despite its historical significance, Plow Shop Pond Dam is classified as having a low hazard potential due to poor condition assessment. The dam's spillway is uncontrolled, and it lacks outlet gates for controlled water release. With a risk assessment rating of moderate, there is a need for improved risk management measures to ensure the safety and integrity of the structure. The Department of Conservation and Recreation oversees the state regulation, inspection, and enforcement of the dam, highlighting the importance of ongoing maintenance and monitoring to mitigate potential risks and protect the surrounding community and environment.
