National Program for Inspection of Non-Federal Dams. Lake Mauweehoo Dam (CT 00321), Housatonic River Basin, Sherman, Connecticut. Phase I Inspection Report
Lake Mauweehoo Dam is a combination earth embankment and stone masonry/concrete dam approximately 225 feet long and 22 feet high. A stone masonry wall averaging approximately 8.5 feet wide and a 24 inch thick concrete facia on the upstream side of the masonry wall runs the full length of the dam. Earth fill lying on a 2:1 slope is on the upstream side of the above-mentioned wall and stone rubble and miscellaneous debris on a 1:1.5 slope lies on the downstream side of the wall. There is a 13.7 foot wide principal spillway and 10 foot wide emergency spillway. There is a 12 inch low-level discharge pipe that passes through the base of the dam. In general, the overall condition of the dam is FAIR. The structural stability of the dam is good as evidenced by its, vertical, horizontal and lateral alignment. Trees are standing along the toe of the dam and its abutments. The downstream end of the emergency spillway channel is washing out. The gate valve and low-level discharge pipe are inoperable. There is seepage through the base of the dam in the vicinity of the outlet to the lowlevel discharge pipe. It is believed that this seepage is coming through the valve on the discharge pipe. The combined spillway capacity of the principal and emergency spillway when the water in the pond is at the top of the dam is approximately 223 cfs. The test flood would overtop the dam by approximately 0.2 feet.
