Minnesota River Navigation Project
Location/Description
|
The St. Paul District is responsible for maintaining the 9-foot channel navigation project on the Minnesota River from the mouth in St. Paul, Minn., to the head of navigation in Savage, Minn., 14.7 miles upstream. The district is also responsible for maintaining the 4-foot channel to mile 25.6 in Shakopee, Minn. Annual channel maintenance actions are required to maintain the congressionally authorized 9-foot channel depth. These channel maintenance activities consist of dredging, snag removal, and close monitoring of the conditions.
The St. Paul District dredges approximately 19,000 cubic yards of material per year from seven distinct locations on the Minnesota River. Both government and contract hydraulic and mechanical dredges are used. Dredged material placement is planned for the long-term and is actively managed to maximize beneficial use of the material and to minimize adverse environmental impacts within the riverine environment.
|
Status
|
Annual operation and maintenance is required to ensure safe, reliable navigation. Coordination with river users, other river resource agencies and the public is crucial to a successful program. Operational agreements have been developed with state regulatory agencies to facilitate channel maintenance.
The Minnesota River 9-foot channel navigation project, effectively the head of navigation for the Upper Mississippi River navigation project, is an essential component of the nation's transportation structure supporting commerce. The Minnesota River transports approximately one-fourth of the 16 million tons annually shipped in and out of Minnesota with an annual economic value in excess of $362 million.
|
The Dredged Material Management Plan for the Minnesota River above the Highway I-35W bridge was approved in 2007. This plan provides the long-term management of dredging and placement site requirements along the Minnesota River for both the Corps and private industry. The Lower Minnesota River Watershed District is the non-federal sponsor for the project. It is responsible for implementing and maintaining the placement sites.
|
Authority
|
In 1892, the River and Harbor Act authorized the maintenance of a 4-foot navigation channel from the mouth to mile 25.6. The River and Harbor Act of 1958 authorized the existing 9-foot navigation channel.
|
Fiscal
|
Operation and maintenance of the project is funded annually under the Corps of Engineers Civil Works Operation and Maintenance appropriation. The average annual funding for the maintenance of the navigation channel on the Minnesota River for fiscal years 2003 through 2005 was $161,000. Funding for the project was not provided in fiscal year 2006. $250 thousand was allocated in July 2007 and made possible urgent dredging that kept the navigation channel open. The project was funded in fiscal year 2008 and is not expected to incur critical funding shortfalls in the future.
