OMAHA | The U.S. Army Corps of Engineers has determined that winter releases from Gavins Point Dam near Yankton, South Dakota, will be at least 17,000 cubic feet per second.
The rate was set after the Sept. 1 Missouri River system storage check.
Drought conditions continue in the upper Missouri River basin, but August runoff above Sioux City was 1.8 million acre-feet, which is 129 percent of average. The 2017 runoff forecast is 28.7 MAF, or 113 percent of average.
With the planned winter releases, all water currently stored in the flood control zone in the system's six reservoirs will be released during the remainder of the year.
