Horsepond Dam is an earth embankment structure with a reinforced concrete core wall. It is 1,900 feet long and has a hydraulic height of 35.2 feet. There are three dikes in saddles near the left end of the dam. The principal spillway is a 30-inch reinforced concrete pipe and discharges to Horse Pond Brook. It acts as the low level outlet. The emergency spillway is a 200-foot long earth embankment on the right side of the dam and also discharges overland through a wooded area to Fivemile River. As a result of the visual inspection and a review of available data, Horsepond Dam is considered to be in fair condition. Major concerns are extensive vehicle trespassing and consequent erosion of the upstream and downstream slopes of the dam and the crests of the three dikes lack of erosion protection on the crest of the dam wheel tracks on the downstream slope of Dike C and trees growing in the reservoir and at the downstream end of the emergency spillway. The maximum spillway capacity with the water level at the dam crest was estimated to be 4,200 cfs, which is approximately the test flood discharge.
