Half-Way Lake National Wildlife Refuge is a 160-acre refuge in North Dakota managed by the U.S. Fish and Wildlife Service through a limited-interest arrangement, with the federal government holding an easement on privately owned land rather than owning it outright. Established to protect habitat for migratory birds and other wildlife, it reflects conservation policies of the 1930s and 1940s, when landowners sold easements that allowed the government to regulate water levels and restrict hunting. The refuge is overseen by the Chase Lake Wetland Management District within the Arrowwood National Wildlife Refuge Complex and is closed to public access except from nearby roads.
