(McWilliams Reservoir)

Columbia & Northumberland Counties
May 17-24, 2004

Dam Number 6, also known as McWilliams Reservoir, is located on the new Roaring Creek Tract of the Wyoming State Forest in Columbia and Northumberland Counties. Currently, fishing is permitted on the state forest property but under catch and release only regulations. Boating is permitted on McWilliams Reservoir. Dam Number 6 lies approximately 3 miles behind a gated road, so access to this water is by hike-in only.
