About Us

What is now known as Great River National Wildlife Refuge began in 1958 as part of Mark Twain National Wildlife Refuge, a sprawling refuge which included units along the Mississippi River in Iowa, Missouri and Illinois. In 1964, part of Mark Twain National Wildlife Refuge was renamed Clarence Cannon National Wildlife Refuge, after a former Missouri Congressman who was instrumental in establishing that part of the refuge. In 2001, the remainder of the Mark Twain National Wildlife Refuge was further separated into four smaller refuges which became Great River National Wildlife Refuge, Two Rivers National Wildlife Refuge, Port Louisa National Wildlife Refuge and Middle Mississippi River National Wildlife Refuge.

The refuge restores and mimics the mosaic of habitats that were historically found along the Mississippi River. Slow moving backwaters, floodplain forests, wetlands, sedge meadows and grasslands combine to provide food, shelter and resting areas for a variety of birds.

Great River National Wildlife Refuge is comprised of six divisions:

  • Delair Division - 1,710 acres in Pike County, IL
  • Cherry Box Division - 298 acres in Shelby County, MO
  • Fox Island Division - 2,009 acres in Clark County, MO
  • Canton Division - 43 acres in Lewis County, MO)
  • Long Island Division - 6,604 acres in Adams County, IL
  • Slim & Haps Island Division - 728 acres in Pike County, MO

The refuge is managed from Clarence Cannon National Wildlife Refuge located in Annada, MO.
