The source of the Eightmile River is a swampy, undeveloped region in the town of East Haddam, Connecticut, centered between Ackley Road, Hall Kilbourne Road, Usher Swamp Road, and Miles Standish Road. The Eightmile River runs for 13.4 mi to Hamburg Cove in the town of Lyme, Connecticut. The East Branch of the river begins 1/10 of a mile west of the junction of Route 85 and Witch Meadow Road, about 1 mile north of Salem, Connecticut. A popular paddling route begins about 3 miles southwest of Salem along Darling Road about a half mile southwest of the junction of White Birch Road. Most of the route is whitewater reaching Class III-IV at its most difficult with some flatwater and quickwater between the rapids. A take-out can be found at the Route 156 bridge just before the river's confluence with the main branch of the Eightmile River.
