About Harrisville Pond
The primary purpose of Harrisville Pond is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Remington, Clinton O., Iii (local government). It impounds the Pascoag River near Burrillville.
The dam stands 22 feet tall and stretches 550 feet across, creates a reservoir covering 18 acres, has a maximum storage capacity of 100 acre-feet, and collects water from a drainage area of 43 square miles. Completed in 1854, the structure is one of the older dams in the region, with over a century and a half of service.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam.
