  • Dredging operations to begin in Manistee Harbor federal channel

    The U.S. Army Corps of Engineers, Detroit District will dredge the Manistee Harbor federal channel to ensure safe navigation as early as Sunday, Sept. 21 — weather dependent. The maintenance project will remove seasonal shoaling at the mouth of the channel, which impacts commercial traffic when left unaddressed.  
  • Corps of Engineers Updates Ohio Harbor Community with FY25-26 Dredging Newsletter

    The U.S. Army Corps of Engineers, Buffalo District has published the Fiscal Year 2025-2026 Ohio Dredging Newsletter to inform stakeholders and the public about the about the status of dredging of Lake Erie harbors and initiatives for the coming year. Dredging of harbors across Ohio ensures accessible depths for large vessels, the continued flow of commodities across the Great Lakes, and the economic viability of United States waterways.
  • Evaluating Transport of Stockpiled Mississippi River System Sand for Beach Nourishment and Other Uses

    The US Army Corps of Engineers (USACE), Rock Island and St. Paul Districts, maintain 876 miles of shallow-draft navigation channels, dredging approximately 2 million cubic yards of clean, fine- to medium-grained sands from these waterways annually. Due to system constraints and certain state regulatory policies, most of this dredged material (DM) is placed in upland and island facilities. As these dredge placement areas fill with sediment, the districts need to remove sediment to create additional storage or seek new land acquisition. While a significant amount of this DM is being locally used beneficially, the current uses are opportunity driven and dictated by proximity. As such, the districts continue to seek alternative beneficial use practices. One major limiting factor to increased beneficial use is the cost of material transport. Per the Federal Standard, USACE will use the least costly DM placement alternatives that are consistent with sound engineering practices and meet federal environmental requirements. Transport beyond traditional placement sites typically costs much more. The analysis described in this report reviews nontraditional transportation modes and routes to match distant needs with river sediment.
  • Gremlin Cove Boat Ramp closed due to low water and sediment buildup at Harlan County Lake

    In response to declining lake levels and heavy sediment accumulation, officials at Harlan County Lake have temporarily closed the Gremlin Cove Boat Ramp, effective immediately. This is the largest and most frequently used boat ramp on the lake, and the closure will also impact access to the North Shore Marina.
  • Numerical Modeling of Coastal Processes with Beneficial Use of Dredged Sediment in the Nearshore at Jekyll Island, Georgia

    Abstract: This report provides numerical model results to assist the US Army Corps of Engineers–Savannah District (SAS). These results evaluate beneficial use alternatives for the sediment from an advance maintenance widener of the Brunswick Harbor Entrance Channel between stations −14+000 and −28+000. This study applied a coastal wave, hydrodynamic and sediment transport model (Coastal Modeling System), and a shoreline change model (GenCade), focusing on developing and simulating placement alternatives. Subaerial placement model results indicate better shore and beach preservation than at the nearshore nourishment. Placing sediment closer to the “transition zone” between the revetment and natural beach will increase the volume of sand that remains in that area. Some sediment is predicted to return to the channel, but these volumes are small fractions of the placed material. GenCade results indicate that the transition zone rock debris decreases shoreline erosion. Removing it has less impact on that area than any of the subaerial nourishments, but this prediction does not include profile equilibration that may occur after the first 4 months. Overall, model results indicate that subaerial placement will have strong positive response at the eroding beach, and related increases to channel infilling rates are relatively small.
  • Army Corps begins Quillayute River maintenance dredging Sept. 1

    U.S. Army Corps of Engineers' routine maintenance dredging in Quillayute River’s inner and outer navigation channels situated on the Olympic Peninsula in Washington, will begin Sept. 1, 2025. The 24/7 dredging operations, expected to be completed by Feb. 28, 2026, will make it safer for local boaters to navigate.
  • Examination of Activated Carbon Losses During Open Water Placement of Amended Dredged Material for Bioaccumulation Control

    Purpose: The purpose of this study was to evaluate the potential losses of both powdered and granular activated carbon (AC) resulting from open water placement of AC-amended dredged material to reduce contaminant bioaccumulation. The study examined the results of model predictions, a laboratory dump test, and a field demonstration project performed at the Ashtabula Lake Erie placement site.
  • Army Corps awards contract for Lewes & Rehoboth Canal dredging

    The U.S. Army Corps of Engineers (USACE) Philadelphia District announced it awarded a $9.6 million contract to Cottrell Contracting Corporation of Chesapeake, Va. to conduct dredging of the Lewes & Rehoboth Canal in Sussex County, Delaware.
  • Army Corps awards contract for Indian River Inlet North Shore beachfill

    The U.S. Army Corps of Engineers (USACE) Philadelphia District has awarded an $8.1 contract to Great Lakes Dredge & Dock Company for dredging and beachfill along the north shore of the Indian River Inlet in Sussex County, Delaware.
  • Corps of Engineers seeks comments on Lock and Dam 7 dredging (Lower approach to Lock and Dam 7)

    ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, is seeking public comments on a draft Environmental Assessment, or EA, for two proposed routine dredge cuts within Pool 8 of the Mississippi River, near Lock and Dam 7 in La Crescent, Minnesota.
