National Program for Inspection of Non-Federal Dams. Stony Brook Dam (MA 00132), Merrimack River Basin, Westford, Massachusetts. Phase I Inspection Report
The dam is a 350 foot long, 24 foot high, gravity, earth embankment structure with a 20 foot long masonry spillway and two sealed outlets. The visual inspection indicated the dam to be in generally fair condition. The deficiencies noted during the inspection include the presence of roots of trees growing on the upstream and downstream faces which could cause internal erosion of the dam; the spillway gates have not been operated in several years; and there is no drawdown facility. Considering the reservoir to be at its normal elevation of 183.5, the spillway can pass 485 cfs or 10 percent of the outflow, resulting in the dam being overtrapped by about 3.3 feet. Raising and or removal of gates will increase discharge capacity to 25 percent.
