National Program for Inspection of Non-Federal Dams. Hattertown Pond Dam (CT 00313), Connecticut Coastal Basin, Newtown, Connecticut. Phase I Inspection Report
The existing Hattertown Pond Dam consists of an earth and rockfill dam approximately 95 feet long, 11 feet high and 8 feet wide at the crest. A 19-foot-long spillway with a concrete crest located at the left dam abutment is the only outlet from the site. The dam is currently owned by Bridgeport Hydraulic Company, Bridgeport, Connecticut and serves no specific purpose, however, the impoundment is used for recreation. The original Hattertown Pond Dam, completed in 1840, was a 12-foot-high earth buttress that impounded Hattertown Pond in the Town of Newton, Connecticut. However neither the purpose nor the exact location of the original structure were available. Based on the visual inspection of the site and the past performance of the dam, the facility is judged to be in very poor condition. Evidence of recent breaches, erosion of the embankment, seepage through the dam, and growth of large trees and brush on the dam were noted. In addition, the spillway section was in a state of extreme disrepair. The test flood outflow is approximately 380 cfs; and the capacity of the spillway, with the water surface at the top of the dam, is 120 cfs or 14 percent of the routed test flood outflow. Therefore, the dam would be overtopped by about 1.5 feet.
