Westville Dam

The Westville Dam is located on the Quinebaug River between Southbridge and Sturbridge, about 1.3 miles (2.1 km) west of the Southbridge town center and 18 miles (29 km) 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 June 1960 with completion in August 1962 at a cost of US$5.6 million.

The Westville reservoir is located within the Quinebaug River Watershed and is part of the Thames River Basin. Access to the site is available from Interstate 84 and State Route 131.
