National Program for Inspection of Non-Federal Dams. Mill Pond Dam (CT 00164), Connecticut River Basin, Newington, Connecticut. Phase I Inspection Report
Mill Pond Dam is an earth-covered, irregular natural rock formation 600 ft. long, with a top width varying from 10 to 20 ft. and a maximum height of 19 ft. The outlet for the dam is a natural rock weir spillway approximately 35 ft. wide, which is overpassed by a footbridge. The crest of the spillway is about 3 ft. below the lowest point on the dam crest. Based on visual inspection, the Mill Pond Dam is judged to be in good condition; however, during the inspection, there was a light snow cover of approximately 2 inches which may have obscured problems, such as erosion or seepage. A test flood of a 100 year frequency was selected in accordance with the Corps of Engineers' Guidelines. The calculated test flood inflow of 1,000 cfs results in a routed outflow of 990 cfs. With the water level at the top of the dam the spillway capacity is 575 cfs which is 58% of the outflow flood. The storage capacity of the Mill Pond is 52 ac.-ft. at the top of the dam.
