  • Corps decreases runoff forecast due to lower than normal mountain snowpack

    The U.S. Army Corps of Engineers Missouri River Basin Water Management Division is decreasing the annual runoff forecast for the Missouri River Basin above Sioux City, Iowa, to 20.3 million acre feet (MAF), which is 80 percent of normal and 4.9 MAF less than average. The decreased forecast is due to below normal mountain snowpack and the lack of plains snow in the basin.

  • Corps invites public to Missouri River operations meetings

    The U.S. Army Corps of Engineers Missouri River Basin Water Management Division will hold five public meetings in early April to update stakeholders on current hydrologic conditions and the planned operation of the Mainstem Reservoir System.

  • February runoff higher, but 2015 Missouri River forecast still slightly below normal

    The U.S. Army Corps of Engineers Missouri River Basin Water Management Division reports runoff in the Missouri River Basin above Sioux City, Iowa was 2 million acre feet (MAF) during February, 186 percent of normal. The increased runoff was caused by above normal temperatures in the upper Missouri Basin that limited river ice build-up, and melted both plains and low elevation mountain snows. However, the 2015 runoff forecast in the same reach is 24.6 MAF, 97 percent of normal, and the March runoff forecast is about 1 MAF less than in February.

  • Missouri River Committe learns efforts on management plan

    The Missouri River Recovery Implementation Committee (MRRIC) met in Kansas City, Mo., February 23–26. At its 28th meeting, MRRIC continued to work with the U.S. Army Corps of Engineers (Corps) and the U.S. Fish & Wildlife Service to develop the Missouri River Recovery Management Plan (Plan). The Committee heard presentations on a range of potential management actions that could benefit the three listed species: the least tern, piping plover, and pallid sturgeon. These actions form the basis for alternatives that can be tested using river models.

  • Corps increases releases due to cold temperatures; normal runoff forecast for 2015
