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.
