  • Notice of Availability of the Beta Streamflow Duration Assessment Methods for the Northeast and Southeast

    Expiration date: 4/12/2023

    The U.S. Army Corps of Engineers (Corps) Baltimore, Buffalo, Charleston, Chicago, Detroit, Fort Worth, Galveston, Huntington, Jacksonville, Kansas City, Little Rock, Louisville, Memphis, Mobile, Nashville, New England, New Orleans, New York, Norfolk, Philadelphia, Pittsburgh, Savannah, St. Louis, Tulsa, Vicksburg, and Wilmington Districts, and the U.S. Environmental Protection Agency (EPA), Regions 1, 2, 3, 4, 5, 6, and 7 jointly announce the availability of the Beta Streamflow Duration Assessment Methods (SDAM) for the Northeast and Southeast (dated April 12, 2023). The methods are rapid assessment tools to help distinguish between ephemeral, intermittent, and perennial streamflow at the reach scale for the Northeast and Southeast SDAM Regions. The beta SDAMs may help provide technical guidance for identifying waters that may be subject to regulatory jurisdiction under Section 404 of the Clean Water Act; however, these methods do not alter or change the definition of “Waters of the U.S.”
