Upper Mississippi River Restoration Program projects and studies

Upper Mississippi River Restoration Program

The U.S. Army Corps of Engineers’ Upper Mississippi River Restoration Program includes studies and projects in the Upper Mississippi River system north of Cairo, Illinois. The system includes the Illinois River. This program, authorized by Congress in 1986, emphasizes habitat rehabilitation and enhancement projects and long-term resource monitoring. The habitat project component includes dredging backwater areas and channels, constructing dikes, creating and stabilizing islands and controlling side channel flows and water levels.

Upper Mississippi River Restoration Program: Conway Lake

The Conway Lake Habitat Rehabilitation and Enhancement Project is located in Pool 9 of the Upper Mississippi River, immediately upstream of Lansing, Iowa. Conway Lake is relatively shallow with abundant aquatic vegetation. Dissolved oxygen depletion is a problem in the lake in summer and in winter. During the winter, excessive water enters Phillipi Lake through openings that are eroding, creating unsuitable habitat conditions for overwintering backwater fish.

Upper Mississippi River Restoration Program: Harper's Slough

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: Lower Pool 10 Islands

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 1 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: McGregor Lake

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.
