  • 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.
