  • U.S. Army Corps of Engineers releases final Almond Lake and Arkport Dam Master Plans

    The U.S. Army Corps of Engineers (USACE), Baltimore District, has released the new Almond Lake and Arkport Dam Master Plans that will serve as the guiding documents for consistent, responsible decision-making at both Flood Risk Management projects for the next 15 to 25 years.

  • MacArthur Lock closing for seasonal repair, maintenance

    The Soo Locks’ MacArthur Lock will close for the Navigation Season to conduct seasonal repairs and maintenance on December 16, 2024. The Poe Lock will remain open until Jan. 15, 2025, or until commercial traffic ceases, whichever occurs first. The Soo Locks operating season is fixed by federal regulation (33 CFR 207.440). “The 800-foot-long MacArthur Lock, built in 1943, is now 81 years old; this maintenance period is critical to keeping the lock in operation during the shipping season,” Maintenance Branch Chief Nicholas Pettit said. The MacArthur Lock has seen 2,806 lockages and 5,170 passages (number of vessels) since opening April 24, 2024, to now, December 12, 2024.

  • Dr. Gary Anderton retires after 30 years at WES/ERDC

    After nearly more than three decades of service to the U.S. Army Engineer Research and Development Center (ERDC)/Waterways Experiment Station (WES), Dr. Gary Anderton bade the agency farewell. ERDC held a retirement ceremony honoring Anderton on November 14 to celebrate his 38 years of service to the agency

  • Retiring from the Corps of Engineers: A Fond Farewell

    For many long-serving U.S. Army Corps of Engineers employees, retirement is a bittersweet moment. On one hand, there is a sense of pride and accomplishment in having served the nation and contributed to important infrastructure projects. On the other hand, there is a sense of loss in leaving behind the camaraderie and a sense of purpose that comes with being part of a military organization.

  • U.S. Army Corps of Engineers announces Disc Golf Course closure ahead of Annual Wheelin’ Hunt

    The U.S. Army Corps of Engineers (USACE), Baltimore District and The National Wild Turkey Federation, Terrace Mountain Chapter will be hosting the 23rd Annual Chris Bowser Wheelin’ Sportsmen Hunt, Saturday, Dec.14, 2024, at the Seven Points Recreation Area. During this time, the Raystown Lake Disc Golf Course and Allegrippis Trail system will be closed. Those visiting the Seven Points Recreation Area on this day are asked to wear orange and be aware of their surroundings.

  • USACE, WDFW sign Project Partnership Agreement for Duckabush Estuary Restoration

    The U.S. Army Corps of Engineers (USACE), and the Washington Department of Fish and Wildlife (WDFW) met a major milestone with the signing of the Duckabush Estuary Restoration Project Partnership Agreement, defining responsibilities, cost-sharing and execution of work between USACE and WDFW, as the non-federal sponsor.

  • Over 300 attend LRD Industry Day

    The U.S. Army Corps of Engineers (USACE) Great Lakes and Ohio River Division (LRD) hosted Industry Day on Wednesday, December 4, from 8:30 a.m. to 5:30 p.m. EST at the Hilton Netherland Plaza Hotel in Cincinnati, Ohio. Over 300 members from different industry sectors attended as they learned about USACE LRD’s regional mission, upcoming opportunities, and network with USACE employees across seven regional districts.

  • Adaptive Hydraulics (AdH) Version 4.7.1 Sediment Transport User’s Manual: A 2D Modeling System Developed by the Coastal and Hydraulics Laboratory

    Abstract: Guidelines are presented for using the US Army Corps of Engineers (USACE) Adaptive Hydraulics (AdH) modeling software to model 2D shallow water problems with sediment transport (i.e., AdH linked to the Sediment Transport Library [SEDLIB]). This manual describes the inputs necessary to use the SEDLIB sediment transport library from within AdH, to perform coupled hydrodynamic, sediment, and morphological computations. The SEDLIB sediment transport library is intended to be of general use and, as such, examples are given for basic sediment transport of cohesive, noncohesive, and mixed suspended sediment loads and bedload.

  • Numerical Modeling of Supercritical Flow in the Los Angeles River: Part II: Existing Conditions Adaptive Hydraulics Numerical Model Study

    Abstract: The Los Angeles District of the US Army Corps of Engineers is assisting the City of Los Angeles with restoration efforts on the Los Angeles River. The city wishes to restore portions of the channelized river to a more natural state with riparian green spaces for both wildlife and public recreation usage. The Los Angeles River provides an important role from a flood-control perspective, and functionality needs to be preserved when contemplating system modifications. This report details the development of an Adaptive Hydraulics numerical model capable of modeling this complex system consisting of both subcritical and supercritical flow regimes. The model geometry was developed to represent the existing conditions system for future usage in quantifying the impact associated with proposed restoration alternatives. Due to limited hydraulic data in the study area, an extensive model validation to observed data was not possible. A model was developed and simulated using the most appropriate input parameters. Given the lack of measured data for model validation, an extensive number of sensitivity simulations were completed to identify the most impactful parameters and quantify a reasonable level of confidence in the model results based on the uncertainty in the model inputs.

  • Many Celebrate Completion of Bois Brule Levee Project

    The U.S. Army Corps of Engineers, St. Louis District, leadership held a ribbon cutting ceremony to celebrate the closeout of the Bois Brule Levee Deficiency Correction Project Dec. 6, that provides resilient infrastructure for flood risk reduction within the 26,000 acres of agricultural lands, commercial businesses and homes in the area protected by the levee. Ongoing efforts led by St. Louis District’s interdisciplinary project delivery team with support from the project sponsor, the Bois Brule Levee Drainage and Levee District, have corrected underseepage and inadequate levee grade issues along the Bois Brule levee in Perry County, Missouri, and Randolph County, Illinois, located on the right descending bank of the Upper Mississippi River between river miles 94 and 111.
