  • Application of Existing Tools to Systematically Identify Nearshore Placement Sites for Beneficial Use of Navigation Sediments in Lake Michigan

    Purpose: The Great Lakes includes 140 federally maintained harbors with an annual dredging program of 2–4 million cubic meters (3–5 million cubic yards)[1] of sediment. Many small harbors are not dredged regularly, and there is an undredged backlog of over 9 million cubic meters (12 million cubic yards) of sediment (USACE-LRD 2021). Current policy (Spellmon 2023) is to maximize the beneficial use (BU) of sediment, with a goal of beneficially reusing 70% of the federal navigation dredging volume by 2030 (that is, the 70/30 goal). In the Great Lakes, clean sands have often been placed on beaches or in the nearshore littoral zone to beneficially nourish the shoreline, but since many harbors are not dredged regularly, no plans exist to beneficially reuse dredged sediments. This lack of existing BU plans is particularly true for harbors with finer grained or mixed sediment. To achieve the 70/30 BU goal and support navigation maintenance and coastal management requires a strategic and systematic approach to identifying BU sites. The purpose of the technical note is to (1) provide an approach to identify potential nearshore placement sites using existing information and models; (2) describe available tools for placement site identification, coastal condition information, and the long-term fate of the sediment; and (3) provide a pertinent case study to describe this approach in practice.
  • Kings Bay Naval Submarine Base Beneficial Use of Dredge Material Study

    Efforts are underway to understand the coastal marsh system surrounding the Kings Bay Naval Submarine Base.
  • Army Corps begins Swinomish maintenance dredging Sept. 9

    U.S. Army Corps of Engineers' routine maintenance dredging in Swinomish Channel, a federal navigation channel located between the eastern shore of Fidalgo Island and the mainland at the western edge of Skagit County, Washington, is scheduled to begin Sept. 9, 2024.
  • USACE shares update on dredging schedule for Manasquan Inlet

    The U.S. Army Corps of Engineers (USACE) Philadelphia District shared an update regarding navigation at the Manasquan Inlet in New Jersey.
  • USACE shares update on Manasquan Inlet

    The U.S. Army Corps of Engineers (USACE) Philadelphia District shared an update regarding navigation at the Manasquan Inlet in Ocean County, N.J. USACE is aware of the shoaling within the Manasquan Inlet inside of the south jetty. Currently, USACE is working to obtain hydrographic surveys of the current inlet conditions. Once completed, this information will be posted online for mariners to access and shared with the U.S. Coast Guard. The USACE Dredge MURDEN is currently scheduled to conduct dredging operations within the inlet later this month and may conduct some operations early this week depending on weather and sea conditions.
  • From waste to resource

    A new project from the U.S. Army Engineer Research and Development Center (ERDC) is helping meet ambitious goals for beneficially using the material it dredges by exploring how 3D printers can transform the dredged sediment into a building block for ecosystem restoration.
  • Jacksonville District issues scoping letter for Naples to Big Marco Pass dredging project

    The U.S. Army Corps of Engineers, Jacksonville District (USACE), is beginning preparation of a National Environmental Policy Act (NEPA) document to address the maneuverability and safety concerns within the federal channel of Gordon and Big Marco passes in Naples, Florida. Collier County is the Non-Federal Sponsor (NFS) for this maintenance dredging project. USACE is currently gathering information to define issues and concerns that will be addressed in an analysis to be prepared in compliance with the NEPA.
  • Army Corps shares update on Salem River dredging

    The U.S. Army Corps of Engineers’ Philadelphia District announced an update on a dredging and marsh restoration project at the mouth of the Salem River in New Jersey. Dredging operations will begin in early July as part of contract that was awarded to Cottrell Contracting Corporation in December 2023.
  • USACE begins Manistee Harbor Channel dredging

    The U.S. Army Corps of Engineers, Detroit District, will begin dredging the Manistee Harbor federal navigational channel June 27 to remove shoaling preventing deep-drafting commercial traffic. About 33,000 cubic years of sediment will be removed from the harbor under a $581,000 contract with King Company of Holland. Funding for the project will come from the Fiscal Year 2022 President’s Budget (PBUD).
  • St. Louis District, U. S. Army Corps of Engineers, Dredge Potter underway for another dredging season

    The Dredge Potter, owned and operated by the U. S. Army Corps of Engineers, St. Louis District, is getting underway today for the 2024 dredging season ensuring safe navigation for commercial vessels on the Illinois and Mississippi Rivers. In 2023, drought conditions required the crew and then 92-year-old vessel to move 6.3 million cubic yards of sand, silt, and clay from the river bottom at 31 different locations.
