Erosion on the bank of the Minnesota River in the Minnesota Valley National Wildlife Refuge is an ongoing issue. The U.S. Army Corps of Engineers is studying how to restore, protect and maintain the integrity of the Continental Grain Marsh and to restore, protect and maintain the riverbank and riparian plant communities to provide a buffer against future adverse hydrologic conditions (i.e., flooding effects). The project area is on the right descending bank of Minnesota River between river miles 15 and 16. This area is managed by the U.S. Fish and Wildlife Service as part of the Minnesota Valley National Wildlife Refuge near Savage, Minnesota. [Go to review plan]

The U.S. Army Corps of Engineers is responsible for maintaining a navigable channel on the Mississippi River. Authority for continued operation and maintenance of the Mississippi River 9-Foot Channel project is provided in the Rivers and Harbors Acts of 1930 and 1932. Original authority for the U.S. Army Corps of Engineers to work on the Mississippi River was provided in the Rivers and Harbors Act of 1878. The purpose of the DMMP is to identify a “Base Plan” for managing dredged material over the next 20-40 years for a particular reach of the river. [Pool 3 / Upper Pool 4 review plan coming soon]

This Procedural Review Plan is intended to ensure quality of reviews by the St. Paul District for requests to alter U.S. Army Corps of Engineers civil works projects within the St. Paul District’s area of responsibility. The plan provides the review guidelines associated with the alteration requests to Title 33 of U.S. Code 408, commonly referred to as Section 408, that are routine, typically of small size, not complex, and have minimal impacts or no impacts to U.S. Army Corps of Engineers civil works projects.
