Located along the Upper Mississippi River, Port Louisa NWR, the northernmost refuge of the Mark Twain complex, is extensively managed to improve habitat conditions for waterfowl and many other species of wildlife. Two of the refuge's four divisions are open to deer and/or upland game hunting (excluding migratory birds). The Big Timber division is the only unit open to waterfowl hunting. Migratory bird hunting is allowed in accordance with state seasons and regulations. Large numbers of puddle and diving ducks flock to the refuge in the fall providing for excellent hunting. Detailed hunting information can be found at the refuge Web site at http://www.fws.gov/midwest/portlouisa/
