Corps of Engineers awards contract to dredge Duluth-Superior Harbor

DETROIT – The U.S. Army Corps of Engineers, Detroit District, awarded a contract for dredging at Duluth-Superior Harbor in western Lake Superior on the Minnesota-Wisconsin border, to begin early August. The $2.72 million contract is awarded to Roen Salvage Co., from Sturgeon Bay, Wisconsin. The contract is to mechanically dredge about 76,000 cubic yards of material from the harbor. The dredged material will be placed at Erie Pier Confined Disposal Facility (CDF) and the 40th Avenue West Placement Area. Dredging will begin in early August and will be complete by November 1, with Erie Pier site work complete by March 2023. “Maintenance dredging executed under this contract will allow ships to safely navigate in the Duluth-Superior Harbor and approximately half of the material will be beneficially used for habitat restoration at the 40th Avenue placement site,” said Project Manager Stephen Rumple.

Corps of Engineers cleaning debris inadvertently placed on Minnesota Point

DETROIT - The U.S. Army Corps of Engineers (USACE) is coordinating cleanup of aluminum cans and can fragments inadvertently deposited on Minnesota Point during dredge material placement in the fall of 2020. USACE placed 49,000 cubic yards of beneficial use dredge material on Minnesota Point at the city’s request during annual Duluth-Superior Harbor maintenance dredging operations in August and September. In 2019, 53,000 cubic yards of dredge material was placed on the south end of Minnesota Point to minimize erosion due to high water and protect old growth trees. The city requested additional material in 2020 to help restore the eroded beach and dune habitat. The debris likely resulted from dredge equipment encountering an area containing trash discarded in the harbor in the 1970s based on aluminum can vintage. About 27,000 cubic yards of dredge material came from the area USACE officials believe contained the debris.
