  • Researchers develop tools to forecast risk of potential infrastructure failure

    The U.S. Army Corps of Engineers (USACE) operates and maintains approximately 740 dams and associated structures that provide significant, multiple benefits to the nation. In order to effectively operate and maintain those dams, USACE applies risk-informed decision making to evaluate, prioritize and justify dam safety decisions. Using risk information allows the organization to repair its dams in the most effective manner within a constrained budget.

  • Levees and Dams at Fort Riley, Kansas, and the Response to the 1951 Flood

    Abstract: This project provides a historic context and inventory for the levees and dams constructed at Fort Riley, Kansas. The purpose of this historic con-text and inventory is to determine the levees and dams’ eligibility for listing in the National Register of Historic Places (NRHP). Determinations of eligibility to the NRHP are then made based on the significance of the levees and dams and the degree to which they retain their integrity for conveying that significance. The authors inventoried and evaluated three levees and two lake dams on the installation. Based on the historic context and inventory, researchers for this project have determined that none of the levees and dams are eligible for the inclusion in the NRHP nor was there enough evidence for a noncontiguous historic district at Fort Riley.

  • Corps to begin construction for fish reefs on Monongahela River

    The U.S. Army Corps of Engineers Pittsburgh District is notifying the public that onsite work to build stone fish reefs on the Monongahela River near the borough of Elizabeth will begin Oct. 30. The work is the first of five segments of a $2.4 million contract to install the fish reefs between Monongahela River miles 21.3 and 33.5. The work will begin at river mile 33.5 in Pool 3, between Victory Hills and the city of Monongahela, and continue downstream to river mile 21.3 in Pool 2 near Clairton, Pennsylvania.

  • NR 23-35: Dale Hollow Dam Road closing for scheduled inspections

  • Evaluation of a Permeable Dam as an Erosion Control Structure on Coca River, Ecuador

    Abstract: The effort performed here describes the process to evaluate the scour-protection performance of the proposed permeable dam. The US Engineer Research and Development Center, Coastal and Hydraulics Laboratory, built a 1:50 Froude scaled movable bed section model of the permeable dam structure and tested in a specialized flume that simulates regressive erosion propagation. Profiles were collected at various times to track the progression of the scour. Tests evaluated variations of the proposed structure, which included tetrapods, riprap, bridge piers, and longitudinal piles. For the various proposed alternatives, a total of six tests were conducted. The collected profiles show the ability or inability of each alternative and its associated performance. From this analysis, untethered tetrapods could not effectively arrest the local scour around the structure. However, large rock along with invert control stopped the regressive erosion and held the upstream grade.

  • NR 23-16: Reservoirs below summer pool elevations due to lack of rain

    NASHVILLE, Tenn. (June 6, 2023) – The U.S. Army Corps of Engineers Nashville District’s water managers report that two reservoirs in the Cumberland River Basin did not receive enough rain this spring to reach their traditional summer pool elevations.

  • Army Corps updates water release schedule for Francis E. Walter Dam

    The U.S. Army Corps Engineers’ Philadelphia District announced an update to the 2023 Francis E. Walter Dam recreation plan. With long-term forecasts showing little significant rainfall, USACE anticipates the four scheduled whitewater releases in June will be reduced and evenly allocated based on available water storage. The projected weekend flow during the reduced whitewater events in June will be announced the Wednesday prior to each event.

  • Hydropower capabilities set to surge on three rivers in Pittsburgh District

    Recently, Rye Development announced they would begin constructing four hydropower plants at lock and dam facilities on the Ohio, Monongahela, and Allegheny rivers. Once construction begins, it can take 24-36 months to complete a facility.

  • Juvenile salmon benefit from spring spill

    In April, the Northwestern Division, U.S. Army Corps of Engineers started spilling water on the Snake and Columbia rivers to help juvenile salmon migrate downstream. We met up with Julie Ammann, Reservoir Control Center chief at Bonneville Lock & Dam to check it out.
