Lower Scoville Reservoir Dam

About Lower Scoville Reservoir Dam

The primary purpose of Lower Scoville Reservoir Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Town Of Wolcott (local government). It impounds the Mad River near Waterbury.

The dam stands 15 feet tall and stretches 600 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 50 acre-feet, and collects water from a drainage area of 8 square miles. Completed in 1917, the structure is over a century old.

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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 12/06/2023.
