The primary purposes of Dexter Marsh Wildlife Management Area (WMA) are for wildlife management, wildlife habitat management, and wildlife-dependent recreation.
This WMA is strictly a wetland area consisting of lands primarily underwater. 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. There are no designated trails,
but hiking is allowed throughout the property.
