Reuben Hart Reservoir Dam is an earth embankment about 1,000 ft. long, 15 ft. wide at the crest, with a maximum height of about 50 ft. The dam is operated by Torrington Water Company as a water supply facility for the city of Torrington. Built in 1933, the original spillway was a concrete ogee overflow 55 ft. long which spilled into Hart Brook. In 1960 a complete revision of the spillway arrangement was undertaken in conjunction with the construction of Hall Meadow Brook Dam, a flood control facility to the east of Reuben Hart Dam. The new service spillway is 125 ft. long and spills into Hall Meadow Brook Reservoir. An auxiliary spillway which spills into Hart Brook has an effective length of about 202 ft. and is 3.5 ft. higher than the service spillway. The outlet works include a wet well shaft with selective level inlets connected to two 18 in. dia. pipes under the dam. Beyond the toe of the dam the two 18 in. pipe join into one 24 in. dia. pipe, which turns 90 degs. about 100 ft. from the toe, where a valve controls discharges through an 18 in. dia. pipe into a small pond on Hart Brook. Reuben Hart Reservoir covers above 130 acres and has a maximum storage capacity of about 3,100 acre-ft. The drainage area is about 5.1 sq. mi. The dam appears to be in good condition. The combined service and auxiliary spillways are adequate to pass the full PMF test flood without overtopping the dam. Two wet areas due to seepage were noted downstream from the toe of the dam. Some riprap on the upstream face has been displaced due to ice jacking. The top of the concrete wall between the dam and spillway has disintegrated.
