This Refuge was created in response to the Great Flood of 1993 . The three parcels of bottomland that now make up this Refuge had been riverine polders , agricultural land protected by dikes . After the dikes were breached by this flood , the damaged land parcels were transferred to the federal government . The Fish and Wildlife Service has announced plans to slowly return these three parcels to the status of semi-natural bottomlands . Pursuant to these plans , the Middle Mississippi River National Wildlife Refuge was established in May 2000
