National Program for Inspection of Non-Federal Dams. Waterbury Reservoir Number 2 Dam (CT 00304), Naugatuck River Basin, Prospect, Connecticut. Phase I Inspection Report.
Abstract
Waterbury Reservoir No. 2 Dam consists of an earth embankment with a downstream stone masonry wall. The dam has a top width of 22 feet, a maximum height of 20 feet, and an overall length of 230 feet including a 40 foot long overflow spillway located near the left end of the dam. The outlet works consist of a gate chamber at the right of the spillway, and a 12-inch cast iron pipe extending approximately 100 feet downstream of the dam. The dam impounds Waterbury Reservoir No. 2 which was formerly used as a storage reservoir for public water supply and currently serves no formal purpose. Based on the visual inspection, the dam is judged to be in poor condition. Features that could affect the future integrity of the dam are seepage at the base of the masonry wall and downstream of the dam; erosion of the upstream slope and crest; and the inaccessibility of the low level outlet or blowoff gates. The spillway capacity with the water level at the top of the dam is 410 cfs and is equal to 156 percent of the test flood routed outflow.
