Mud Creek is a small, sluggish stream that flows from the Canadian border south to Lake Champlain. The WMA consists primarily of a mix of emergent marsh and forested swamp, which provide habitat for a variety of waterfowl, including black ducks, wood ducks, mallards and teal, as well as other wetland birds. Below the marsh, from the dam downstream to the lake, Mud Creek also offers great paddling opportunities as well as fishing. In the fall Mud Creek offers good duck hunting, especially on its main marsh, which is regulated as a controlled hunting area. From September 1st to December 31st it is open only to waterfowl hunters with a valid permit.
