National Program for Inspection of Non-Federal Dams. Manitook Lake Dam (CT 00672), Connecticut River Basin, Granby, Connecticut. Phase I Inspection Report
Manitook Lake Dam is a composite masonry and earth dam consisting of two masonry building foundations, separated by an 18 ft. long masonry wall and an upstream earth embankment. The entire length of the dam is about 108 ft. long. The lake behind the dam is about 6,500 ft. long and has a surface area at spillway crest level of about 92 acres. The drainage area above the dam is 1.53 sq. mi. and the maximum storage to top of dam is estimated at about 667 acre-ft. The dam is judged to be in fair condition at the present time owing to the absence of an operative dewatering facility and lack of recent maintenance. Seepage, estimated at 20 gpm, was noted at the downstream toe of the 18 ft. long wall which connects the two building foundations. The test flood inflow for the facility equals 2,250 cfs. The routed test flood outflow of 1,580 cfs overtops the dam by 1.77 ft. The spillway can pass 97 cfs or about 6 percent of the routed test flood outflow without overtopping the dam.
