  • Scoop and restore: Pittsburgh District dredges Monongahela River to support navigation industry

    A U.S. Army Corps of Engineers Pittsburgh District contractor dredges soil, rocks and other materials from the Monongahela River south of Pittsburgh.

  • Corps of Engineers seeks comments on river sand placement site in Winona County, Minn.

    ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, is seeking public comments on a draft Environment Assessment, or EA, for a proposed river sand placement site in Winona County, Minnesota. The sand will be beneficially used by Fastenal Company for construction of a warehouse.

  • Corps of Engineers begins Grays Harbor maintenance dredging April 8

    USACE's hopper dredge vessels, Yaquina and Essayons, begin Grays Harbor outer harbor maintenance dredging April 8. The maintenance navigation dredging is required in the harbor area, whose deep draft channel is 350 feet wide increasing to 1,000 feet over the bar, to support Washington State's economy that relies on navigation and commerce.

  • U.S. Army Corps of Engineers issues Draft Environmental Assessment for the Everglades Harbor and Channel Project

    JACKSONVILLE, Fla. (Mar. 10, 2025) – The U.S. Army Corps of Engineers (USACE), Jacksonville District pursuant to the National Environmental Policy Act (NEPA) issues the Notice of Availability (NOA) of the Draft Environmental Assessment (EA) and Proposed Finding of No Significant Impact (FONSI) for the Everglades Harbor and Channel Project, Collier County, Florida.

  • Jacksonville District publishes updated Fernandina Harbor NEPA proposal for public review, comment

    The U.S. Army Corps of Engineers, Jacksonville District, seeks public review and comment regarding

  • Norfolk Harbor Navigation Improvements Project: Modeling of Dredged Material Placement Schemes and Long-Term Sediment Transport at the Dam Neck Ocean Disposal Site

    Abstract: US Army Corps of Engineers–Norfolk District requested assistance with the development and evaluation of dredged-material-placement schemes that evenly distribute placed material and avoid or minimize unacceptable mounding in accordance with the site management and monitoring plan. A multiple placement fate and transport modeling study was conducted to determine the optimal placement plan for dredged material from Thimble Shoals Channel and Atlantic Ocean Channel at the Dam Neck Ocean Disposal Site (DNODS). Provided the large volume of dredged material to be placed at DNODS over a short duration during the construction period, a modeling study was performed using the Geophysical Scale Multi-Block (GSMB) modeling system to determine the transport and fate of placed dredged material at the DNODS that is resuspended by currents and waves over a 2-year period. Six scenarios were undertaken to determine the best path forward. Scenarios 1 and 4 were excluded due to high exceedance of the depth threshold. Scenarios 2, 3, 5, and 6 yielded an approximate 1%–2% dispersal of placed materials from the DNODS during ambient environmental conditions; Scenario 6 yielded the least. Most dispersion occurred during two simulated hurricanes. The model findings generally support the DNODS Environmental Impact Statement and site-designation documents.

  • Temporary Recreation Area Closings To Conduct Dredging Activities at Lake Shelbyville

    The U.S. Army Corps of Engineers at Lake Shelbyville will be performing dredging work on the North end of the lake in 2025. Work will include dredging of the Kaskaskia river channel, starting at the Whitley Creek boat ramp and heading towards the Illinois Highway 32 bridge, located south of Sullivan, IL.

  • LA District commander meets with congressman, discusses Oceanside shoreline mitigation

    U.S. Army Corps of Engineers Los Angeles District commander Col. Andrew Baker met with California’s 49th Congressional District Rep. Mike Levin Feb. 20 to discuss the status and future of Oceanside shoreline mitigation.

  • Lower James River Sediment Transport Modeling: Jordan Point

    Abstract: US Army Corps of Engineers–Norfolk District (NAO) requested assistance from the US Army Engineer Research and Development Center (ERDC) to examine currently used placement sites within the James River, Virginia, initiative area, determine potential risk to critical environmental receptors during placement, and predict the life cycle of the placement sites. The focus of the analysis within this work is the Jordan Point placement site. The far-field, fate-transport modeling at Jordan Point shows relatively low maximum values of suspended sediment concentration (less than 40 mg/L) and deposition values (less than 0.2 cm). Material that is placed at Jordan Point appears to quickly disperse through the system, depositing in thin layers at specific areas. The life-cycle analysis performed for the Jordon Point placement site yielded an estimated useable project life of the Jordan Point placement sites of 26 years with an uncertainty of ±4 years. Analysis showed that 97% of the net sediment deposition in the navigation channel in proximity to this site is from the upper James River, 2% is from downstream sources, and 1% is from the two Jordan Point placement sites.

  • U.S. Army Corps of Engineers Deploys the Murden for Dredging Operations in Lake Montauk

    NEW YORK – The U.S. Army Corps of Engineers (USACE), New York District, is deploying the Wilmington District, shallow draft dredge, Murden, to Lake Montauk to conduct vital dredging operations aimed at maintaining safe and efficient navigation for commercial and recreational vessels.
