Slade National Wildlife Refuge (NWR) is located in south-central North Dakota within the Prairie Pothole Region of the glaciated plains. In an area famed for its wealth of waterfowl producing potholes, the Refuge also provides excellent habitat for nesting grassland birds. Slade NWR received its name from a Northern Pacific Railroad executive G.T. Slade. Slade donated the property to the U.S. Fish and Wildlife Service in 1941.
