Thomaston Dam is located on the Naugatuck River in Thomaston, Connecticut, and is a part of a network of flood control dams and local protection projects built by the U.S. Army Corps of Engineers in the Naugatuck River Basin. The Dam was constructed at a cost of $14.2 million and was completed in 1960 in response to the destructive flood of 1955. Thomaston Dam can store up to 13.7 billion gallons of water for flood control purposes.

The Reservoir Regulation Team (RRT), is the "nerve center" for the New England flood control dams such as Thomaston Dam. Using radio and satellite communications, RRT constantly monitors river levels and weather conditions that influence flood control decisions.

Corps personnel, in conjunction with RRT, regulate the amount of water released downstream by raising or lowering the two 5'8"X 10' gates located in the control tower at the dam. In a time of high water, the gates are lowered in order to hold back the water, only to be released when downstream river conditions begin to recede.
