National Program for Inspection of Non-Federal Dams. Wintonbury Dam (CT 00494), Connecticut River Basin, Bloomfield, Connecticut. Phase I Inspection Report
Wintonbury Dam consists of an earth embankment, approximately 1,625 ft. long, with a top width of 12 ft. and a maximum height of 23 ft. The principal spillway consists of a two stage reinforced concrete intake riser discharging through a 30 inch, 145 ft. long reinforced concrete pipe under the dam embankment. The emergency spillway is a trapezoidal grassed channel 110 ft. wide at the control section with its crest 4.5 ft. below the top of the dam. Based on visual inspection and review of available plans and reports, Wintonbury Dam is judged to be in good condition. Some features found existing that could affect the stability of the dam are wheel ruts on the crests and slopes, damage by burrowing animals, and sloughing and eroding of the east and west slopes of the downstream pool area. The dam is a flood control project and therefore the reservoir is dry except during periods of heavy rainfall. With the reservoir dry, the inspection could not reveal seepage conditions. The spillway is capable of passing 300 per cent of the routed test flood outflow without overtopping the dam. The storage capacity to the top of the dam is 1,750 ac.-ft. and up to the test flood level is 1,240 ac.-ft.
