National Program for Inspection of Non-Federal Dams. Shepaug Reservoir Dam (CT 00665), Housatonic River Basin, Litchfield and Warren, Connecticut. Phase I Inspection Report
Shepaug Reservoir Dam is a 500 foot long gravity concrete and earth embankment dam. The concrete gravity section is 390 feet long and has a maximum height of 65 feet. The earth embankment section is 110 feet long with a height of about 35 feet. The top width of the concrete section is 12 feet. The visual inspection of Shepaug Reservoir Dam indicated that the dam is in good condition. The inspection revealed that an erosion feature has developed on the intermediate berm of the downstream slope adjacent to the tunnel entrance. There is some minor sloughing of the downstream slope of the embankment about 60 feet east of the gatehouse. The inspection also revealed areas of wet concrete which indicate seepage near the downstream toe of the spillway in the center one-third of the spillway section and considerable spalling of concrete. The spillway will discharge 18,725 cfs or 75 percent of the test flood with the pool level at the top of the dam. The test flood flow of 24,850 cfs will overtop the dam by 1.4 feet.
