  • ERDC Researchers Co-lead Multiagency Team to Service Prototype Underwater Acoustic Deterrent System

    Researchers from the U.S. Army Engineer Research and Development Center (ERDC), along with scientists from the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE) and other partners, are currently working on a project to test the effectiveness of underwater sound technology on invasive carps — Bighead Carp, Silver Carp, Black Carp and Grass Carp — and the response of various native species of interest throughout the Mississippi River and Great Lakes basins, as well as additional native watersheds.
  • Researchers analyze, share DUNEX data for coastal resiliency

    As the 2023 hurricane season begins, participants in the U.S. Coastal Research Program (USCRP)-supported During Nearshore Event Experiment (DUNEX) are hard at work to analyze their collected data and share their results with other coastal researchers and the broader coastal community.
  • Lake Okeechobee releases planned for Sediment Study on February 21 through 24

    The U.S. Army Corps of Engineers (USACE) Jacksonville District plans to execute a minor adjustment to the current lake release schedule from Tuesday, February 21 through Friday, February 24, that will release water from Lake Okeechobee as part of an ongoing sediment study by the South Florida Water Management District (SFWMD) and the U.S. Geological Survey (USGS).
  • Lake Okeechobee releases planned for Sediment Study on August 23

    The U.S. Army Corps of Engineers (USACE) Jacksonville District plans to execute a minor deviation Tuesday, August 23 that will release water from Lake Okeechobee as part of an ongoing sediment study by the South Florida Water Management District (SFWMD) and the U.S. Geological Survey (USGS).
  • Upper Mississippi and Illinois Rivers Experiencing Widespread and Regional Changes

    The U.S. Army Corps of Engineers, Rock Island District; and the U.S. Geological Survey, in partnership with others, have released a report regarding the Ecological Status and Trends of the Upper Mississippi and Illinois Rivers. The Status and Trends report is the third of its kind produced as part of the Upper Mississippi River Restoration (UMRR) program and includes information on long term changes in water quality, aquatic vegetation and fish from six study areas spread across the Upper Mississippi and Illinois Rivers. The report also summarizes trends in possible drivers of long-term changes in the river including river discharge and floodplain land cover.
  • Lake Okeechobee releases planned for Sediment Study on June 22

    The U.S. Army Corps of Engineers (USACE) Jacksonville District plans to execute a minor deviation June 22 that will release water from the lake as part of an ongoing sediment study by the South Florida Water Management District (SFWMD) and the U.S. Geological Survey (USGS). The releases will affect only the Julian Keen, Jr. Lock and Dam (S-77) as water is released to support the study.
  • USACE Vicksburg District, U.S. Geological Survey conduct first-ever airborne geophysical survey

    VICKSBURG, Miss. – An 800-pound dart-shaped instrument is the latest tool to map beneath the surface of levees in a partnership between the U.S. Army Corps of Engineers Vicksburg District and the U.S. Geological Survey. For the first time, a regional geophysical survey will provide a full overview of 800 miles of the Mississippi River mainline levees. Sometimes called a bird, the frequency domain system suspended from a helicopter will use frequency technology similar to LiDAR to differentiate between various soil layers and penetrate about 150 feet under the surface. 
  • Lake O flows adjusted to support Sediment Study

    The U.S. Army Corps of Engineers (USACE) Jacksonville District will make temporary deviation to the Lake Okeechobee release schedule this week to facilitate a study by the South Florida Water Management District (SFWMD) and U.S. Geological Survey (USGS) to develop methods to indirectly measure sediment transported from the lake to the estuaries.
