About Bristol Blake State Reservoir Dam

The primary purpose of Bristol Blake State Reservoir Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Ma Department Of Conservation & Recreation (state). It impounds the Stony Brook near Norfolk.

The dam stands 15 feet tall and stretches 250 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 180 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1700, the structure is one of the older dams in the region, with over a century and a half of service.
