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.

Upper Mississippi River Restoration Program: Robinson Lake Habitat Restoration, Pool 4, Minnesota

Sedimentation of the backwater lakes of the Upper Mississippi River, including the lower Pool 4 area, is an ongoing issue. Potential sources of sand are the Chippewa River, historic channel maintenance dredging side-cast islands and the four active temporary placement sites within the study area. The extent of open water has been shrinking in Robinson Lake.
