Runoff in the Missouri River Basin above Sioux City, Iowa, was 1.9 million acre feet (MAF) during October, 155 percent of average, according to the U.S. Army Corps of Engineers (Corps). The 2016 calendar year runoff forecast is 24.1 MAF, 95 percent of average. Average annual runoff is 25.3 MAF. The total volume of water stored in the Mainstem Reservoir System on November 1 was 57.2 MAF, occupying 1.1 MAF of the 16.3 MAF combined flood control storage zones. “System storage declined less than anticipated during October, only 0.2 MAF, as a result of heavy rainfall over north central Montana and northwestern Wyoming. During the remainder of fall and winter, we will complete the evacuation of the flood zones of the reservoirs to ensure we start next year’s runoff season with the full flood control capacity of the system available,” said Jody Farhat, chief of the Corps’ Missouri River Basin Water Management Division.
