    Upper Mississippi River Restoration Program: McGregor Lake Prairie Du Chien, WI

    McGregor Lake is a 200-acre backwater lake in Pool 10 of the Mississippi River near Prairie du Chien, Wisconsin. The proposed project could include various features, such as dredging the lake, restoring or strengthening the barrier islands and constructing small islands within the lake to reduce wave action. It could also improve adjacent forest habitat.

  • Upper Mississippi River Restoration Program: Lower Pool 10 Islands, Guttenberg, Iowa

    Lower Pool 10 Islands restoration project is a side channel/island complex located on the Iowa side of the Mississippi River navigation channel in Pool 10, about one mile upstream from Lock and Dam 10 in Guttenberg, Iowa. The proposed project goals include protecting and restoring island complexes in this 1,000 acre area that would restore and enhance quality habitat for native and desirable species by reducing suspended solid concentrations and reducing wind fetch.

  • Upper Mississippi River Restoration Program: Lake Winneshiek

    Lake Winneshiek is a 6,000 acre backwater lake on the Wisconsin side of the Mississippi River navigation channel in lower Pool 9 about 4 miles downstream from Lansing, Iowa. The proposed project would create two islands, each about 8,000 feet long, in the center of Lake Winneshiek to reduce wave action in this large, open water area. If suitable construction material can be found in the backwater area, dredging would provide up to 20 acres of additional deepwater habitat.
  • 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.

  • Upper Mississippi River Restoration Program: Conway Lake, Lansing, Iowa

    Dissolved oxygen is essential for a healthy fisheries habitat. Dissolved oxygen depletion is a problem in the study area in summer and in winter due to a variety of reasons. Conway Lake is relatively shallow with abundant aquatic vegetation. During the winter, excessive water enters Phillipi Lake through openings that are eroding, creating unsuitable habitat conditions for overwintering backwater fish. Shore Slough has less than optimal fish habitat conditions as a result of sedimentation and the high flows from Phillipi Lake.
