  • Below average runoff forecasts for upper Missouri River Basin continue

    Runoff continues to be below average in the upper Missouri River Basin above Sioux City, Iowa. Below-normal precipitation, dry soil conditions in the western portions of the basin, and cooler-than-normal temperatures slowing mountain snowmelt, resulted in a May runoff of 2.7 million acre-feet. While this was 0.4 MAF more than forecast last month, this volume is still 79% of average.

  • Below average runoff continues for the upper Missouri River Basin

    “The runoff in February was less than predicted, and we expect the lower-than-average runoff to continue in the coming months,” said John Remus, chief of the U.S. Army Corps of Engineers’, Missouri River Basin Water Management Division. “The snow accumulation in both the plains and the mountains continues to be below average, and the soil moisture remains very low compared to normal. This resulted in us lowering our anticipated runoff for the 2022 water year.”
  • Below average runoff forecast for the upper Missouri River Basin in 2022
