Missouri River system storage declining, Gavins point winter releases set at minimum rate

August runoff in the Missouri River Basin above Sioux City, Iowa was 1.0 million acre-feet (MAF), 73% of average. Runoff was well below normal in the Fort Peck and Garrison reaches due to dry soil moisture conditions and areas of below-normal precipitation. Runoff was above normal for the Oahe, Fort Randall, and Gavins Point reaches, and near normal in the Sioux City reach, mostly due to above-normal precipitation during parts of August.
