  • Missouri River water management public meeting presentations available online

    The U.S. Army Corps of Engineers’ Missouri River Water Management Division has released four videos of presentations that would normally be given at public meetings held throughout the Missouri River Basin. In-person public meetings on Missouri River Mainstem Reservoir System operations originally scheduled for April were canceled to further reduce potential exposure to COVID-19. Instead, the agency will host virtual question and answer sessions in late April. A web page with the videos, a form for submitting questions, and call in dates and times is located here: https://go.usa.gov/xvBpc.
  • Forecast runoff for upper Missouri River basin lower after warm spring

    Gavins Point releases are forecast to remain near 35,000 cubic feet per second through the month of April. The upper Missouri River basin March runoff fell in line with the March 1 forecast. Runoff above Sioux City, Iowa was 5.5 million acre feet, which is almost two times average. The above average runoff was primarily due to plains snow melting over heavily saturated soils. “The warmer-than-normal temperatures melted most of the plains snow in the eastern and central Dakotas. Along with the steady, but near average, rate of snow accumulation in the mountains, the projected upper Missouri River basin runoff for 2020 has been slightly reduced,” said John Remus, chief of the U.S. Army Corps of Engineers’ (Corps) Missouri River Basin Water Management Division.
  • Missouri River Basin runoff remains above normal due to widespread rainfall

June precipitation was above normal across much of the Missouri River Basin, most notably in the western Dakotas, eastern Montana and eastern Wyoming. Heavy rain also fell in eastern Nebraska, northeastern Kansas and much of Missouri.
