    Habitat Restoration: Mississippi River, Harpers Slough, Pool 9, Iowa

    Part of the Upper Mississippi River Restoration Program, the Harpers Slough area is a 4,150-acre backwater area located primarily on the Iowa side of the Mississippi River in Pool 9, about 3 miles upstream of Lock and Dam 9. The site is in the Upper Mississippi River National Wildlife and Fish Refuge. The area is used heavily by tundra swans, Canada geese, puddle and diving ducks, black terns, nesting eagles, bitterns and cormorants and is also significant as a fish nursery area. Many of the islands in the area have been eroded or lost because of wave action and ice movement. The loss of islands allows more turbulence in the backwater area, resulting in less productive habitat for fish and wildlife.
