The East Brimfield Dam is located on the Quinebaug River in Sturbridge, Massachusetts, approximately 20miles southwest of Worcester, Massachusetts.
Designed and constructed by the United States Army Corps of Engineers, this dam substantially reduces flooding along the Quinebaug and Thames rivers. Construction of the project began in 1958 with completion in 1960 at a cost of $6,580,000.[1]
The East Brimfield Reservoir, located in Sturbridge and Brimfield to its west, lies within the Quinebaug River Watershed and is part of the Thames River Basin. Access to the site is available from US Route 20.
The project consists of a rolled earth fill dam with stone slope protection 520feet long and 55feet high. Cut in rock, the spillway comprises a concrete weir 75feet in length. The weir's crest elevation is 19.2 feet (7.0 m) lower than the top of the dam. The permanent lake at East Brimfield Dam, East Brimfield Reservoir (which includes Long Pond, a natural body of water that was enlarged by the dam's pool) is 360acres in size. Also located on the project are numerous natural bodies of water that are not affected by the dam under normal conditions, but are raised and inundated when the reservoir is filled for flood control. These include the 65acres Lake Siog, and the 15acres Lost Lake. The flood storage area for the entire project covers about 2270acres in the towns of Sturbridge, Brimfield, and Holland, Massachusetts. The entire project, including all associated lands, covers 2070acres. The East Brimfield Dam can store up to of water, equivalent to 9.7 billion (thousand million) gallons, for flood control purposes. This is equivalent to 8.3inches of water runoff from its drainage area of 67.5sqmi.
