The Upper Mississippi River Wildlife and Fish Refuge is located along 284 miles of the Mississippi River valley extending from the confluence of the Chippewa River near Wabasha, MN to near Rock Island, IL. The lands that make up the refuge lie in four states: MN, WI, IA, IL. The Refuge is largely confined to the floodplain. The Refuge provides migratory habitat for a large percentage of the migratory birds in the Mississippi Flyway. Tundra swans and canvasback ducks use the Refuge as a resting and feeding area in the spring and fall.
