About Woonsocket Reservoir # 3

The primary purpose of Woonsocket Reservoir # 3 is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Woonsocket Water Division (local government). It impounds the Crookfall Brook near North Smithfield.

The dam stands 28 feet tall and stretches 1,500 feet across, creates a reservoir covering 227 acres, has a maximum storage capacity of 4,740 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1895, 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. Notably, no emergency action plan is currently on file for this high-hazard dam.
