The U.S. Army Corps of Engineers, Detroit District, reported today that work to remove sediment from the Duluth/Superior Harbor is in full swing now.
“The contractor for the project – Roen Salvage Company Sturgeon Bay, Wis. – has been making great progress on the contract and is even ahead of schedule,” said the Corps.
Duluth-Superior Harbor, MN. & WI. is located at the extreme western end of Lake Superior.
Each year over 100,000 cubic yards of material is being dredged from Duluth-Superior Harbor, the minimum amount of dredging required to keep the harbor open for shipping.
The existing project provides for the reconstruction of channels within the harbor, St. Louis Bay, and St. Louis River. These channels vary in depth from 32 to 28 feet in the entrance; are 27 feet deep in the iron-ore route channels and 20 to 23 feet in inner channels.
There are over 18 miles of maintained channels in the harbor, with widths varying from 250 feet to over 3700 feet in basins.
