  • USACE Buffalo District updates Ohio harbor community with dredging newsletter

    The U.S. Army Corps of Engineers Buffalo District has published the Ohio Dredging Newsletter to inform stakeholders and the public about the nine Lake Erie Harbors it supports across the state.

  • Largest Annual Great Lakes Dredging Operation Completed in Toledo

    The U.S. Army Corps of Engineers (USACE), Buffalo District has completed annual dredging of Toledo Harbor and the Maumee River. Dredging of Toledo Harbor is the largest dredging operation on the Great Lakes, ensuring accessible depths for large vessels, the continued flow of commodities across the lakes, and the economic viability of United States waterways.

  • ‘Man Overboard’: Dredge vessel crew saves woman swept away by Columbia River

    It was the sound – something like a scream – that first caught their attention.

  • Ranking Ports by Vessel Demand for Depth

    Abstract: The US Army Corps of Engineers (USACE) traditionally uses two metrics to evaluate the maintenance of coastal navigation projects: tonnage at the associated port (representing relative importance) and the controlling depth in the channel (representing operating condition). These are incorporated into a risk-based decision framework directing funds where channel conditions have deteriorated and the disrupted tonnage potential is the highest. However, these metrics fail to capture shipper demand for the maintained depth service provided by the USACE through dredging. Using automatic identification system (AIS) data, the USACE is pioneering new metrics describing vessel demand for the channel depth, represented by vessel encroachment volume (VEV). VEV describes the volume of the hull intruding into a specified clearance margin above the bed and captures how much vessels use the deepest portions of USACE-dredged channels. This study compares the VEV among 13 ports over 4 years by combining AIS, tidal elevations, channel surveys, and sailing draft. The ports are ranked based on the services demanded by their user base to inform the decision framework driving dredge funding allocations. Integrating demand for-depth metrics into the Harbor Maintenance Fee assessment and/or Trust Fund disbursements could alleviate the constitutionality concerns and several criticisms levied against Harbor Maintenance funding.

  • U.S. Army Corps of Engineers Awards Contract to Dredge Erie Harbor

    The U.S. Army Corps of Engineers (USACE), Buffalo District awarded a $682,000 contract to Michigan-based Ryba Marine Construction Co. on Dec. 6 to conduct dredging of the federal navigation channel in Erie Harbor. Dredging of harbors like Erie’s ensures accessible depths for large vessels, the continued flow of commodities across the Great Lakes, and the economic viability of United States waterways.

  • Dredging Neah Bay Entrance Channel will improve Strait of Juan de Fuca, Salish Sea oil spill response

    An Emergency Response Towing Vessel (ERTV) stands ready 24/7 on the northwestern Olympic Peninsula point in the Port of Neah Bay, Washington to quickly respond to disabled or distressed vessels. But a U.S. Army Corps of Engineers project to improve navigation by deepening the harbor entrance channel will improve ERTV readiness and maneuvering during low tides.

  • Corps of Engineers Completes Nearly $20 Million in Cleveland Harbor Maintenance

    The U.S. Army Corps of Engineers Buffalo District completed $19.5 in maintenance and repairs to Cleveland Harbor in 2023. This year’s work included annual maintenance dredging in the Cuyahoga River and significant repairs to the harbor’s more-than century old breakwater, ensuring safe access for vessels, the flow of commodities across the Great Lakes, and the economic viability of the nation’s waterways.

  • USACE Vicksburg District's celebrates 90 years of service

    VICKSBURG, Miss.-- The U.S. Army Corps of Engineers (USACE) Vicksburg District’s Dredge Jadwin marks 90 years of service to the nation on Oct. 30, and she will not be taking a day off to celebrate.

  • Proceedings from the Basin Sediment Management for Unique Island Topography Workshop, Mayagüez, Puerto Rico

    Abstract: This report summarizes the Basin Sediment Management for Unique Island Topography Workshop hosted in-person and virtually at the University of Puerto Rico Mayagüez (UPRM) Department of Civil Engineering and Surveying, Mayagüez, Puerto Rico on 11 March 2022. The workshop was attended by approximately 80 federal, state, local, and academic organizations participants. It focused on Engineering With Nature® (EWN®), green infrastructure (GI) and low impact development (LID) opportunities for unique tropical island topography and included seven presentations from subject matter experts, a discussion on limitations and problems with prior projects, and two concurrent breakout sessions. Preworkshop activities included a field trip to multiple sites in the Añasco watershed conducted 09 March 2022, which served as a base case for the workshop. The field trip provided participants a unique perspective of the island’s topography and post 2017 Hurricane María issues and impacts. During the breakout sessions, participants identified new project opportunities for EWN®-GI and LID at two selected sites from the field trip. Each group developed alternatives for their chosen site and identified concepts that could turn into great opportunities for the surrounding communities and significantly benefit the state of practice in Puerto Rico’s unique tropical island topography.

  • Army Corps awards contract for Ocean City, Strathmere, Sea Isle City beachfill project

    The U.S. Army Corps of Engineers’ Philadelphia District awarded a contract to Great Lakes Dredge & Dock Company of Oak Brook, Ill. for $33.7 million to complete periodic nourishment of the Great Egg Harbor Inlet to Townsends Inlet Coastal Storm Risk Management project. The project is a joint effort of the Army Corps’ Philadelphia District, the New Jersey Department of Environmental Protection, and Ocean City, Sea Isle City, and Upper Township, N.J. Work is designed to maintain the dune and berm system in the communities and reduce the risk of storm damages to coastal infrastructure.
