The US Army Corps of Engineers’ (USACE) Detroit District has awarded a contract for dredging at Duluth-Superior Harbor in western Lake Superior on the Minnesota-Wisconsin border.
The more than US$2 million contract was awarded to Roen Salvage, from Sturgeon Bay, Wisconsin. The work calls for the dredging of approximately 91,000 cubic metres of material from the harbour.
Approximately 40,000 cubic metres of the mostly sandy material will be placed along North Minnesota Point shoreline and approximately 52,000 cubic metres of material will be placed at Interstate Island.
Dredging will begin within this month and will be completed by mid-November.
The Detroit District worked with federal, state, and local partners to beneficially use the dredged material to nourish Minnesota Point, which will help stabilise and re-build eroded shoreline and dune habitat along Lake Superior. Meanwhile, material placed at Interstate Island will help to restore critical tern nesting habitat that has been lost to erosion.
