Public Notices

  • Notice of Availability of the Beta Streamflow Duration Assessment Method for the Great Plains

    Expiration date: 9/28/2023

    The U.S. Army Corps of Engineers (Corps) Albuquerque, Chicago, Detroit, Fort Worth, Galveston, Kansas City, Omaha, Rock Island, St. Louis, St. Paul, and Tulsa Districts, and the U.S. Environmental Protection Agency (EPA), Regions 5, 6, 7, and 8, jointly announce the availability of the Beta Streamflow Duration Assessment Method (SDAM) for the Great Plains (dated September 2022). The method is a rapid assessment tool to help distinguish between ephemeral, intermittent, and perennial streamflow at the reach scale for the Northern and Southern Great Plains SDAM Regions. The beta SDAM may help provide technical guidance for identifying waters that may be subject to regulatory jurisdiction under Section 404 of the Clean Water Act; however, this method does not alter or change the definition of “Waters of the U.S.”
