1,339 acre Wildlife Management Area, primarily underwater. Situated seven miles west of Watertown, just off Route 180, at the head of the Black River Bay, Dexter Marsh is strictly a wetland area consisting of lands primarily underwater. Easily accessible from three state boat launching facilities; Perch River off Co Rt 59, Muskellunge Creek on State Route 180 and Lloyds Landing off Old Military Road. This 1350-acre marsh is a popular fish and waterfowl area. Northern pike, bass and panfish are found in the shallow to deep water, and a variety of ducks, black terns, shore birds and marsh waders utilize the sparse cattail marsh which characterizes this Lake Ontario bay. Canada geese are often seen during their migration. Bald eagles are occasionally seen over the marsh.
