en.Wedoany.com Reported - The U.S. Army Corps of Engineers (USACE) Detroit District will commence maintenance dredging at the outer harbor of St. Joseph Harbor, Michigan, in early July 2026. The project, awarded to Viking Marine Construction, LLC of Holland, Michigan, involves dredging approximately 83,000 cubic yards (about 63,500 cubic meters) of sediment from the federal navigation channel. Using hydraulic dredging methods, the sediment will be transported via underwater pipeline to a location approximately 0.5 miles (about 800 meters) south of the harbor, with completion expected by the end of August 2026.
St. Joseph Harbor, located on the eastern shore of Lake Michigan in southwestern Michigan, is a key commercial and recreational port in the Great Lakes region. The harbor's channel is a federally authorized navigable waterway, and regular maintenance dredging is critical to ensuring normal port operations and safe vessel navigation. The USACE Detroit District is responsible for the maintenance and management of Great Lakes ports and waterways within Michigan, Indiana, and Ohio.
According to the U.S. Army Corps of Engineers, this year's dredged material disposal method differs from previous years. Historically, dredged material was typically placed along the shoreline to reduce erosion; this year, however, it will be arranged perpendicular to the shoreline to form a peninsula-like structure. The USACE Engineer Research and Development Center (ERDC) will conduct a specialized study on this unique placement method to better understand the movement patterns of dredged material under wave action. The study will employ various techniques, including turbidity monitoring, nearshore topographic surveys, sediment sampling, and the use of drones and land-based video recording.
Viking Marine Construction, LLC, headquartered in Holland, Michigan, is a specialized dredging and marine engineering contractor with extensive experience in dredging projects across the Great Lakes region. The St. Joseph Harbor dredging project is another federal channel maintenance project undertaken by the company. The innovative dredged material disposal method employed in this project will provide valuable research data and practical references for the scientific management of dredged material at Great Lakes ports.
