The Nepaug River begins at the confluence of North Nepaug Brook and Cedar Swamp Brook about 1 mile east of Bakersville, Connecticut. It runs for 10.6 miles (17.1 km) to the Farmington River about a half mile south of Cherry Brook, Connecticut. A large dam about 1 mile from the Farmington River creates Nepaug Reservoir which is about 2 miles long from north to south and about 1 mile wide running east-west.
