Five Mile River

The Five Mile River is a river located in Connecticut's northeast corner which flows through the towns of Thompson, Putnam, and Killingly. The original Nipmuc name was Assawaga, meaning "place between" or "halfway place". The Assawaga received its English name from the fact that the first land laid out upon it was "supposed to be about five miles from" Woodstock, Connecticut. The Five Mile is a tributary of the Quinebaug River and is part of the Thames River watershed. Its source is Little Pond, close to the Massachusetts border. It empties into the Quinebaug River at Danielson, near the intersection of Connecticut [Route 12] and U.S. Route 6.
The Five Mile River has several dams, most of which are remnants of defunct mills and some of which are still used by local industry. Its largest impoundment is Quaddick Reservoir. The best examples of surviving mill villages are Killingly in villages such as Pineville, Ballouville, Attawaugan, and Dayville [Historic District|Dayville].
