National Program for Inspection of Non-Federal Dams. Wilton Pond Dam (CT 00284), Lower Housatonic River Basin, Plymouth, Connecticut. Phase I Inspection Report.
Abstract
Wilton Pond Dam is a stone masonry structure 42 feet long with a maximum height of 16 feet. A centrally located depressed spillway section has been grouted and passes water over the dam. There is no outlet works associated with the dam. Wilton Pond is used as fire pond by the Town of Plymouth and functions as a passive recreational area. The lake has a maximum storage volume of 63 acre-feet. The dam is judged to be in generally poor condition. Seepage is evident around the right end of the dam exiting through gaps in the stone masonry and the right abutment area. Erosion is taking place on the left abutment and extensive grass cover was noted at the right side of the dam. The recently reconstructed spillway section is in good condition. The capacity of the spillway is inadeqaute to pass the 100 year storm test flood outflow (631 CFS) without overtopping the dam. the test flood would overtop the dam by about 0.7 feet. The spillway is adequate to pass 42 percent of the test flood outflow without overtopping the dam.
