Lake Ilo National Wildlife Refuge is one of over 560 refuges and 38 wetland management districts in the National Wildlife Refuge System-a network of lands set aside specifically for wildlife. Managed by the U.S. Fish and Wildlife Service, the Refuge System is a living heritage, preserving wildlife and habitat for people today and for generations to come.

Lake Ilo National Wildlife Refuge was established in 1939 by Franklin D. Roosevelt as a breeding ground for migratory birds and other wildlife. The Refuge provides fish and wildlife-oriented recreational opportunities, conserves endangered species, and protects cultural and natural resources.

      The primary purpose of Lake Ilo National Wildlife Refuge is to provide nesting and brood-rearing habitat for waterfowl. However, Refuge staff use a variety of habitat management techniques to maintain, enhance, or recover habitat for all wildlife on the Refuge. Refuge staff carefully use management tools such as livestock grazing, prescribed burning, noxious weed control, mowing, seeding, and water management. Sometimes, sensitive areas are closed to the public so that the land can recover more quickly.
