Arapaho National Wildlife Refuge

The Arapaho National Wildlife Refuge is a United States National Wildlife Refuge located in north-central Colorado. It is one of over 560 national wildlife refuges which manages and protects natural resources for future generations. The refuge is located in North Park in central Jackson County south of the town of Walden. The refuge was established in 1967 to furnish waterfowl with a suitable place to nest and rear their young. It was created in part to offset losses of nesting habitat in the prairie wetland region of the Midwest. It is located in the valley of the Illinois River, a tributary of the North Platte River. It is administered by the United States Fish and Wildlife Service.
