Navigation: Pool 3 and Upper Pool 4 Dredged Material Management Plan – Dakota and Washington and Goodhue County, Minnesota, and Pierce County, Wisconsin

The U.S. Army Corps of Engineers operates and maintains the Upper Mississippi River 9-Foot Channel Navigation Project, and one method the Corps uses to keep the channel the right size is dredging river soils or “material.” The purpose of the DMMP is to prepare a coordinated, long-term plan for managing dredged material in Pool 3 and Upper Pool 4. This plan was initiated due to needs for dredged material management upland placement sites.
