Bolivar Pond Dam is an earth embankment approximately 150 feet long. Both the upstream and downstream faces of the dam are vertical stone walls. Bolivar Street, which is approximately 40 feet wide, is located on the crest of the dam. The concrete overflow service spillway is located approximately 250 feet right of the dam. The drop-inlet closed conduit auxiliary spillway is located about 175 feet to the right of the service spillway. The dam appears to be in poor condition. Several indications of structural cracking are apparent on both the upstream wall and the downstream wall which is a wall of the Town of Canton DPW garage. About 5 gpm seepage was noted discharging from the downstream wall inside the Town of Canton garage. The dam does not have a reservoir drain system. The test flood inflow for the facility is approximately 9,410 cfs. The routed test flood outflow of 9.405 cfs overtops the dam by 2.9 feet. The spillway system is able to pass 115 cfs or about 1 percent of the routed test flood outflow without overtopping the dam.
