National Program for Inspection of Non-Federal Dams. Cold Spring Reservoir Dam (CT 00495), Connecticut River Basin, Bloomfield, Connecticut. Phase I Inspection Report
Cold Spring Reservoir Dam consists of an earth embankment, approximately 1,040 ft. long, with a top width of 12 ft. and a maximum height of 20 ft. In addition, there is a 140 ft. long dike, 2.5 ft. high, with an 8 ft. top width. The two outlets for the dam are the principal spillway and emergency spillway. The principal spillway is a drop inlet structure consisting of a two stage reinforced concrete intake riser discharging through a 36-in. reinforced concrete pipe under the dam embankment. The emergency spillway is a trapezoidal grassed channel, 125 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, Cold Spring Reservoir Dam is judged to be in fair condition. Some features found existing that could affect the stability of dam are erosion of the dam embankment and the potential foundation and embankment stability problem resulting from the existing soil conditions. 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 174% of the routed test flood outflow without overtopping the dam.
