National Program for Inspection of Non-Federal Dams. Mercers Pond Dam (CT 00068), Housatonic River Basin, Danbury, Connecticut. Phase I Inspection Report
Mercers Pond Dam is an earth embankment approximately 400 feet long and 17 feet high. Granite blocks line the downstream face (250 feet). A 39-foot long spillway is located at the western end of the dam. There is a 24-inch discharge pipe with a slide gate on the upstream face of the dam. The gate is not operable. The drainage basin is 4.5 square miles on which 3.3 square miles is controlled by another dam upstream. There is approximately 61 acre-feet of storage available. The assessment of the dam is based on the visual inspection, past operational performance and hydraulic/hydrologic computations. The dam is judged to be in fair condition with several areas that require attention. These areas include seepage along the toe of the dam, the poor condition of the stone face and the nonoperating status of the discharge pipe. The dam is classified as small and has a high hazard potential in accordance with guidelines established by the Corps of Engineers. The test flood for these conditions is the Probable Maximum Flood (PMF). The test flood inflow is 6,150 cfs and the routed test flood outflow is 5,885 cfs. The test flood will overtop the dam by 2.75 feet.
