National Program for Inspection of Non-Federal Dams. Beaver Dam Lake Dam (CT 00083), Housatonic River Basin, Stratford, Connecticut. Phase I Inspection Report
Beaver Dam Lake Dam is a 1300 foot long earth embankment dam and has a maximum height of 47.3 feet. The top width of the dam is 16 feet. The spillway is located on the left side of the embankment. It appears that the original earth embankment am which was approximately 20 feet in height was raised 27 feet to its present height. The visual inspection of Beaver Dam Lake Dam indicated that the dam is in fair condition. The inspection revealed the existence of a foot path along the entire crest of the dam. The right 800 foot long portion of the dam shows the crest of the dam to be sloping toward the reservoir (upstream) by as much as 12 inches. Riprap in some areas of the upstream slope of the embankment has been eroded. The upstream gatehouse foundation has separated from the gate chamber wall by as much as 3 inches and this crevice extends to a depth of 5 feet below ground surface. An extensive growth of grass, briars, rosebushes and brush cover the upper downstream slope of the embankment. The lower slope is covered with grass, brush and many trees. Also, numerous animal holes up to 12 inches in diameter were observed on the downstream face of the dam. The spillway will pass the test flood outflow of 1225 cfs with a pool elevation of 176.15 feet which is 1.65 feet below the top of the dam.
