Abstract:

The dam was originally constructed of rubble masonry with upstream and downstream earth embankments. In 1928 the dam was reconstructed by removing the upstream earth embankment, constructing a 3-12-ft. concrete facing on the upstream face and a concrete cap on the crest, and constructing a new concrete spillway and brick gatehouse. The dam has a maximum height of 17 feet. The spillway is located in the center of the dam and is 20 feet wide and 2 feet below the crest of the dam. Ledge was exposed in the spillway channel. The dam appeared to be in good condition, with only some minor concrete spalling along the crest and lower training wall. The capacity of the impoundment between the dam and U.S. Route 1 is about 11 Acre-Feet. Failure of the dam would release only this lower portion of the impoundment as the highway embankment is unlikely to fail. There is ample storage capacity in the downstream reach to dissipate the flood wave from a failure of Beaver Brook Dam.
