West Thompson Lake

West Thompson Lake is a 200-acre lake in Thompson, Windham County, Connecticut.

A dam was constructed in 1965 by the United States Army Corps of Engineers to create the lake. It impounds the Quinebaug River for flood control and seasonal storm water management. The dam is owned and operated by the Corps of Engineers.

The dam is one of the six flood control structures built on the river. This network of dams helps control flooding all the way from the upstream tributaries of the Thames River to the Long Island Sound. The West Thompson Dam was constructed in 1965. It cost 6.7 million U.S. dollars.

The West Thompson Lake has a total storage capacity of 342 million gallons of flood water.
