Fish and Wildlife Service, Missouri.
Clarence Cannon National Wildlife Refuge was established in 1964 with funds from the purchase of migratory waterfowl stamps. It lies in Pike County, Missouri, Pool 25 about one mile east of the small town of Annada, Missouri.
The refuge was named in honor of Congressman Clarence Cannon who was influential in its establishment. The area was formerly part of an agricultural levee district and all but a few hundred acres is encompassed by a levee. The refuge covers 3,750 acres of Mississippi River floodplain and was established to provide a feeding and resting area for migratory birds. The refuge is comprised of managed moist soil units, open water, wet meadows and bottomland forest habitats.
The refuge office is also the headquarters for Great River National Wildlife Refuge and Middle Mississippi National Wildlife Refuge.
