Within the northernmost fringes of the Pine Barrens, the Turkey Swamp area is located on a ridge, being a major drainage divide within Central New Jersey. It includes the headwaters of the Manasquan that flows into Manasquan Inlet, and the Metedeconk and Toms River systems that flow into Barnegat Bay, to the east; the Manalapan Brook system that is part of the Raritan River basin, to the north; and the Assunpink and Crosswicks systems that flow into the Delaware River, and the Millstone River system that also flows to the Raritan, to the west. The chief recreational attraction of this park is the 17-acre (6.9 ha) lake suitable for bass, bluegill and catfish fishing, as well as canoeing and paddle boating.
