About Warren Pond Dam
The primary purpose of Warren Pond Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by American Woolen Co., Inc. (private). It impounds the Furnace Brook near Stafford Springs.
The dam stands 22 feet tall and stretches 293 feet across, creates a reservoir covering 9 acres, has a maximum storage capacity of 135 acre-feet, and collects water from a drainage area of 16 square miles. Completed in 1852, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 10/28/2021.
