  • Soo Locks Closing for Seasonal Repair, Maintenance

    SAULT STE. MARIE, Mich. - 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 Detroit District 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.”
  • High winds, storms, wave action increase hazards

    The U.S. Army Corps of Engineers, Detroit District, urges caution around Great Lakes harbor piers and breakwaters, particularly during high wind and wave events. Accidents can occur near harbor structures during turbulent weather late in the year. The lakeshore attracts residents and visitors who may not be aware of the powerful impacts strong winds and storms can bring to shorelines and harbor structures. “Although breakwater structures are built for navigation, they are often used for recreation,” said Chief of Operations and Maintenance Branch, Cindy Jarema. “Walking along breakwater structures can be hazardous – surfaces may be slippery and uneven, and wave action increases the risk of injury or falling into the water.”

  • Army Corps to keep Crooked River Lock in Alanson closed to complete repairs

    The Crooked River Lock in Alanson, Michigan will remain closed for the remainder of the season to perform critical maintenance this fall. This decision was made Thursday, September 14, 2023 between the U.S. Army Corps of Engineers, Detroit District (USACE) and Emmet County leadership for the safety of the public. Replacement parts for a faulty safety relay allowing the lock to reliably open and close remain on backorder. The Detroit District, in conjunction with Emmet County, which operates the lock under an agreement with the Michigan Department of Natural Resources, decided Thursday to close the lock early for the season for safety of the public, and to conduct a thorough inspection and development of a robust repair plan to prevent unscheduled 2024 closures.

  • U.S. Army Corps resumes Grand Haven dredging with additional E.coli testing

    The U.S. Army Corps of Engineers, Detroit District (USACE) will resume dredging in Grand Haven Harbor on Wednesday, July 12, with additional testing for E. Coli and safety measures. King Co. Inc., under an Army Corps contract, will dredge the remaining 35,000 of 141,000 cubic yards of sediment contracted to be removed from the outer harbor in Grand Haven to keep the commercial channel navigable throughout the remainder of the year. The Army Corps paused dredging at the location Friday, July 7, out of an abundance of caution after the Ottawa County Health Department issued a “no body contact” warning because of high concentrations of E. coli at North Park Beach in Ferrysburg. The remaining dredging will take about seven days to complete, weather dependent
  • Corps of Engineers to begin dredging, beach nourishment in South Haven

    The U.S. Army Corps of Engineers, Detroit District will begin hydraulically dredging the federal navigation channel and nourishing the South Haven Harbor shoreline next week.

  • Dredging in Grand Haven targeting mid-July completion

    Detroit -- The U.S. Army Corps of Engineers, Detroit District (USACE) is currently utilizing 24-hour dredging in Grand Haven, Michigan during favorable weather to remove shoaling blocking Grand Haven Harbor from commercial traffic. The project is expected to be completed in mid-July. Severe weather and minimal ice cover during the winter led to increased shoaling in several harbors on Lake Michigan this year, blocking large commercial vessel traffic. Grand River commercial docks are struggling to receive shipments due to the unexpected shoaling. The King Co., Inc. of Holland, Michigan is on-site and contracted to clear 141,000 cubic yards of sand from the federal channel at Grand Haven, just beyond the pierheads. The material will be placed 7,000 to 10,000 feet north of the north pier onto the beach and into the nearshore area between the Ordinary High-Water Mark (OHWM) and the most-landward 12 feet depth contour in the lake. The placement area borders the Ottawa County North Beach Park and several properties along North Shore Drive. The contract, awarded Feb. 28, required the work to begin in Holland and Grand Haven harbors when the weather allowed in the spring using hydraulic dredging for speed and cost. Unusually windy and wavy conditions during March and April delayed dredging work in Holland.
