    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.

    Pool 9 Dredged Material Management Plan – Houston County, Minnesota, Allamakee County, Iowa, and Vernon County, Wisconsin

    The purpose of the DMMP is to prepare a coordinated long-term plan for managing dredged material in Pool 9. This plan was initiated due to needs for dredged material management upland placement sites, especially in the upstream reach of the pool. The Pool 9 Dredged Material Management Plan (DMMP) study area is located between Lock and Dam 8 at Genoa, Wisconsin, and Lock and Dam 9 near Lynxville, Wisconsin, spanning more than 31 river miles from 679.2 to 648.0. The study area includes several communities near the main navigation channel including Lansing, Iowa, and De Soto, Wisconsin.
  • Upper Mississippi River Restoration Program: Reno Bottoms, Pool 9, Upper Mississippi River

    The primary objective of this project is to protect, restore, or create resilient and diverse bottomland forests. The quality and extent of the unique forest and aquatic habitat in the Reno Bottoms project area has been declining over the past several decades. Human caused changes in hydrology, land use, and climate have increased water levels within the project area. Without action, the project area will continue to degrade. The quality of forest and aquatic habitat will decrease. Invasive grasses would expand into forests, limiting opportunities for smaller trees to grow and reducing habitat value. Additional loss of wetland habitat would adversely affect migrating waterbirds and songbirds who require the floodplain forest to stop and rest.
