National Program for Inspection of Non-Federal Dams. Park Pond Dam (CT 00632), Dike (CT 01708), Naugatuck River Basin, Winchester, Connecticut. Phase I Inspection Report
Park Pond Dam, located at the eastern end of the pond, consists of an earth embankment with a maximum height of 20 feet and a top width which varies from 8 feet to 15 feet. The dam is 420 feet long and has a 19.9 foot concrete spillway at the left end. A diversion channel from an adjacent watershed connects to the spillway approach channel. The impoundment has a maximum storage capacity of 1,100 Acre-Feet. The dike, located at the northwestern end of the pond, consists of an earth embankment with a paved roadway along the crest. The dike has a maximum height of 7 feet, a top width of 21 feet, and a length of about 80 feet. Based on the visual inspection, the dam is judged to be in poor condition and the dike in fair condition. Features which could affect the future integrity of the dam are trees and brush on the embankment; seepage through the embankment; erosion of the downstream slope; deterioration of the spillway approach channel wall and the spillway weir; the accumulation of debris in the spillway and approach and discharge channels; the location of the low level control valve downstream of the dam and lack of erosion protection on the dike. The spillway capacity with water level at the top of the dam and the dike is 310 cfs or 58 percent of the Test Flood routed outflow. The Test Flood would overtop the dam and dike by 0.3 feet.
