National Program for Inspection of Non-Federal Dams. Beseck Lake Dam (CT 00381), Connecticut River Basin, Middlefield, Connecticut. Phase I Inspection Report
Beseck Lake Dam is an ashlar masonry and earth embankment dam about 36 ft. high. It is curved and is about 285 ft. long. An earthfill forms the upstream face of the dam, the downstream face being of masonry. The spillway occupies the central 98.5 ft. of the crest length. The non-overflow sections each side of the spillway have earth dikes on top of the masonry. A 20 in. dia. outlet pipe projects through the downstream face of the dam. Flow regulation is by means of a 24 in. dia. sluice gate and stoplogs in a concrete control structure. Riprap on the upstream face is missing in the vicinity of the catwalk to the outlet tower, causing erosion to occur. There are a number of leaks through the masonry downstream face and at the foundation level. A discussed outlet pipe is also leaking. There is some excessive growth on the crest of the dam, on the masonry downstream face and in the downstream channel. The outlet pipe is of inadequate size for rapid evacuation of the reservoir. The dam appears to be in a generally good condition. The spillway is adequate to pass the 1/2 PMF test flood outflow of about 2,150 cfs without overtopping the earth dikes on the non-overflow abutments.
