Flint Hills National Wildlife Refuge in east-central Kansas protects 18,463 acres along the Neosho River floodplain upstream from John Redmond Reservoir. Established in 1966 as part of the reservoir's flood control project and managed by the U.S. Fish and Wildlife Service, it includes prairie grasslands, bottomland hardwood forest, shallow wetlands, and croplands. This varied habitat supports migratory birds and resident wildlife, and it is especially significant as a spring and fall stopover for thousands of waterfowl. Recognized as an Important Bird Area, it also provides winter habitat for bald eagles and other raptors while serving the public through outdoor recreation and educational programs.
