  • Soo Locks Closing for Seasonal Repair, Maintenance

    The Soo Locks in Sault Ste. Marie, Michigan will close to all marine traffic beginning 11:59 p.m. January 15, or until commercial traffic ceases, through 12:01 a.m. March 25 to perform seasonal critical maintenance. Federal regulation (33 CFR 207.440) establishes the operating season based on the feasibility of vessels operating during typical Great Lakes ice conditions. “Every year, the Corps of Engineers uses the non-navigation winter period to perform maintenance and keep the Soo Locks operating,” Maintenance Branch Chief Nicholas Pettit said. “The Soo Project Office team works long hours in extreme conditions to complete a significant amount of maintenance during this annual closure period. The work they perform is unique, especially given the harsh northern Michigan winter conditions they work in.”

  • Corps of Engineers, Navy collaborate in experimental dredging for U.P. harbor

    The U.S. Army Corps of Engineers, Detroit District and Engineer Research and Development Center in partnership with the U.S. Navy removed over 25,000 cubic yards of material from Little Lake Harbor in the Upper Peninsula of Michigan this fall.   Little Lake Harbor, designated as a harbor of refuge, requires annual maintenance dredging. The harbor had severe shoaling and emergency dredging was completed in 2023.   This year, a unique opportunity with the Corps of Engineers Engineer Research and Development Center (ERDC) and the U.S. Navy arose.   “We were working with ERDC on redesigning the federal structures at Little Lake Harbor and ERDC was working with the Navy on experimental training,” said Soo Project Office, St. Marys River Section Chief Justin Proulx. “ERDC brought the two of us together to train the Navy on opening harbors and dredging the Detroit District’s shoaled in Little Lake Harbor.”
