Corps Awards Duluth Dredging Contract

The Detroit Engineer District recently awarded a contract for dredging at Duluth-Superior Harbor in western Lake Superior on the Minnesota-Wisconsin border. The more than $2 million contract was awarded to Roen Salvage Company, Sturgeon Bay, Wis. The contract is to dredge about 120,000 cubic yards of material from the harbor. 

Approximately 52,000 cubic yards of the mostly sandy material will be placed along the North Minnesota Point shoreline, and about 68,000 cubic yards of material will be placed at Interstate Island. Dredging began in August and will be complete by mid-November.

“Maintenance dredging executed under this contract will allow ships to safely navigate in the Duluth-Superior Harbor, and the dredged material will be beneficially used for beach nourishment and habitat restoration,” said Melissa Bosman, project manager.

The Detroit Engineer District worked with federal, state and local partners to beneficially use the dredged material to nourish Minnesota Point, which will help stabilize and rebuild eroded shoreline and dune habitat along Lake Superior.  Material placed at Interstate Island will help to restore critical tern nesting habitat that has been lost to erosion.
