    Expiration date: 12/5/2023

    The Lower Platte South Natural Resource District (LPSNRD) is proposing the construction of a water quality basin (Piening Water Quality Basin), spillway, and dam structure within the Pawnee Lake and Middle Creek HUC 12 (102002030202) watershed as part of the LPSNRD Water Quality Management Plan (WQMP). The dam structure is an earthen embankment approximately 889 feet in length. The dam would create a reservoir with a normal pool surface area of approximately 12.2 acres at an elevation of 1,311 feet. The drainage basin area of the Piening Water Quality Basin would be approximately 512 acres. The applicant’s project purpose is to maximize reductions of Atrazine, phosphorus, nitrogen, and sediment loadings as a result of surface runoff from a contributing 524- acre subbasin of the Pawnee Lake and Middle Creek HUC 12 watershed per the LPSNRD WQMP. The basic project purpose, as defined by the USACE, is water quality management.

  • 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.”
