National Program for Inspection of Non-Federal Dams. Chestnut Hill Reservoir Dam (MA 01113), Charles River Basin, Boston, Massachusetts. Phase I Inspection Report.
Abstract
Chestnut Hill Reservoir Dam is an 82-year old earth embankment structure used as a reserve source of water for the City of Boston water distribution system. The embankment is approximately 2,000 feet long with a maximum height of about 18 feet and a top width of 20 feet. The dam is considered to be in fair condition. Saplings have been recently planted on the downstream face, it is not known if the gates and gate valves in Effluent Gatehouses 1 and 2 are operable, many animal burrows were observed on the downstream face and the catch basin system at the downstream toe of the embankment appears to be completely plugged. The test flood for the facility is 22.9 inches of rainfall falling directly on the reservior. Since the reservior surface level is constantly maintained as close as possible to the normal level, which is 4 feet below the top of the dam, chances of the embankment being overtopped during the test flood event are extremely remote.
