Dredged Material Management Plan: Pool 3 and Upper Pool 4—Minnesota and Wisconsin

The Pool 3 and Upper Pool 4 Dredged Material Management Plan study area is located between Lock and Dam 3 near Red Wing, Minnesota, and the southern tip of Lake Pepin at Reads Landing, Minnesota, spanning roughly 51 river miles from 764 to 815.2. The U.S. Army Corps of Engineers operates and maintains the Upper Mississippi River 9-Foot Channel Navigation Project, and one method the U.S. Army Corps of Engineers uses to keep the channel the right size is dredging river soils or “material.”
