Pascoag Reservoir Upper

About Pascoag Reservoir Upper

The primary purpose of Pascoag Reservoir Upper is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is private-owned. It impounds the Brandy Brook near Burrillville.

The dam stands 27 feet tall and stretches 475 feet across, creates a reservoir covering 500 acres, has a maximum storage capacity of 9,000 acre-feet, and collects water from a drainage area of 8 square miles. Completed in 1860, 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.
