  • Old Hickory Dam tailwater boat ramp temporarily closed for debris cleanup

    HENDERSONVILLE, Tenn. – The U.S. Army Corps of Engineers Nashville District announces that the tailwater launching ramp and fishing platform below Old Hickory Lock & Dam, in Old Hickory, Tenn., is closing on Wednesday, Feb. 12, for contract crews to remove debris and downed trees from the nature trail and surrounding areas after an EF2 tornado passed over the project in Dec. 2023.

  • ERDC inducts three leaders into Senior Executive Service

    The U.S. Army Engineer Research and Development Center (ERDC) recently inducted Patricia Sullivan, Nick Boone and Dr. Robert Moser into the Senior Executive Service (SES) during a ceremony at ERDC Headquarters in Vicksburg, Mississippi.

  • Beneficial Use of Dredged Material for Submerged Aquatic Vegetation Habitats: Overcoming Challenges and Seeking New Opportunities

    Purpose: There is a critical need to maintain and create conditions that are conducive for long-term survival of submerged aquatic vegetation (SAV) habitats, which provide multiple ecosystem services, using dredged material. This technical note (TN) was developed by the US Army Engineer Research and Development Center (ERDC)–Environmental Laboratory (EL) to address the specific challenges US Army Corps of Engineers (USACE) practitioners at the district and division level face that impede the development of beneficial use of dredged material (BUDM) projects to restore, conserve, and expand SAV habitats. Different ways to overcome these challenges and opportunities that should be further explored are also addressed. The information in this TN was synthesized from discussions at a virtual workshop for USACE practitioners.

  • A Late Start - Continuing to Serve

    At 62 years of age, most people are thinking about what to do in retirement. Some are even enjoying the fruits of their labor that comes with it. But at 62, Ronald Morris decided to start a career with the U.S. Army Corps of Engineers, Fort Worth District.

  • Corps awards its last major contract for the Fargo-Moorhead diversion project

    The U.S. Army Corps of Engineers, St. Paul District, awarded a $10.1 million contract to BCSS, LLC, of Tempe, Arizona, Jan. 30, to complete the Southern Embankment Reach SE-5 portion of the Fargo, North Dakota/Moorhead, Minnesota, Metropolitan Area Flood Risk Management Project, which is also known as the FM Area Diversion.

  • USACE lifts small craft advisory for Arkansas River

    The U.S. Army Corps of Engineers is lifting the small craft advisory for the Arkansas River. Small craft advisories are issued when flows reach 70,000 cubic feet per second.

  • MKARNS Nav Notice No. SWL 25-10 Lock 10 Intermittent Delays

    Mariners should expect to experience intermittent delays at Dardanelle Lock (No. 10) NM 205.5 on February 6, 2025 between the hours of 7:00 a.m. and 5:30 p.m. daily. The intermittent delays are required to facilitate an underwater ROV inspection of the upstream river wall.

  • Notes on Bedload Sediment Collector Deployment: Eau Claire River, Wisconsin

    Purpose: A bedload sediment collector field deployment was conducted during low flow conditions from August 2023 to September 2023 on the Eau Claire River, Wisconsin, to assess the operation and performance of a 12 ft bedload sediment collector (BSC). This initial deployment of the technology served to familiarize the research team with the new 12 ft BSC system in preparation for its potential deployment during high flow conditions and at other locations. The insights from this study are intended to identify opportunities to use this technology, particularly in the Upper Mississippi River navigation system.

  • Mediated Model Development for Coastal Marsh Management in the Chesapeake Bay

    Purpose: The purpose of this technical note is to develop a conceptual model that describes the critical processes, stressors, and interactions that affect coastal marsh dynamics within the Chesapeake Bay, as identified by subject matter experts, and then link those factors to specific management actions. Managing coastal marshes within Chesapeake Bay involves multiple stakeholders across federal, state, local, and nongovernmental agencies. Reaching consensus among large stakeholder groups can be difficult, since each has their own perspective and requirements for management. Mediated modeling is a technique that facilitates consensus building among stakeholders and provides a transparent roadmap for decision-making. This technical note describes how mediated modeling was applied to marsh management in Chesapeake Bay. On 4–5 May 2022, The Nature Conservancy (TNC) and the US Army Engineer Research and Development Center (ERDC) Integrated Ecological Modeling Team (EcoMod) partnered for a multistakeholder mediated modeling workshop to (1) build a conceptual model that depicts the relevant processes impacting marsh dynamics, and (2) identify indicators that are necessary for tracking marsh conditions, which inform needed management strategies. This conceptual model provides the foundation for the development of a marsh management decision framework that will use indicators to identify marsh conditions that subsequently trigger management decisions.
