    Resident engineer Scott Baker, center, during the weekly progress meeting and site visit Aug. 11, 2015, for the Harper’s Slough project. The Harper’s Slough Habitat Rehabilitation and Enhancement Project, located within the Upper Mississippi River National Wildlife and Fish Refuge, was planned and designed under the authority of the Upper Mississippi River Restoration Program. It will protect five existing islands and construct an additional seven islands using material from the backwater and main channel. The program emphasizes habitat rehabilitation and enhancement projects and long-term resource monitoring. Project component includes dredging backwater areas and channels, constructing dikes, creating and stabilizing islands and controlling side channel flows and water levels. Once the project is completed, the project will be turned over to the U.S. Fish and Wildlife Service, who manages the refuge.

    Upper Mississippi River Restoration Program: Harpers Slough, Pool 9, Iowa

    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 project will protect five existing islands and construct an additional seven islands using material from the backwater and main channel. The project will slow the loss of existing islands, reduce the flow of sediment-laden water into the backwaters, reduce turbidity and increase the diversity of land and shoreline habitat.
