Lake Ilo National Wildlife Refuge

Dunn Center, North Dakota


Lake Ilo National Wildlife Refuge lies in gently rolling, mixed grass prairie in a semi-arid region. It is an oasis for many species of wildlife. The refuge was established in 1939 following the impoundment of the 1,240 acre Lake Ilo. The U.S. Fish and Wildlife Service manages the land for diversity of wildlife with emphasis on migratory birds. The grasslands, planted forested areas, Lake Ilo and numerous smaller wetlands are habitat for many species of animals.

Lake Ilo National Wildlife Refuge is one of a system of refuges administered by the U.S. Fish and Wildlife Service for the preservation of wildlife. The financial base to buy refuges was firmly established in 1934 through the passage of the Migratory Bird Hunting Stamp Act. This Act requires waterfowl hunters to annually purchase a migratory bird or "duck stamp". Funds from duck stamp sales are used to purchase refuges that provide habitats necessary to sustain a wide variety of wildlife for both hunters and non-hunters to enjoy. The U.S. Fish and Wildlife Service seeks to afford persons with disabilities full accessibility or reasonable accommodation. Contact Audubon Complex Headquarters for information or to address accessibility problems.
