The updated 2023 calendar year runoff forecast for the Missouri River Basin above Sioux City, Iowa, continues to be below average, the Corps of Engineers reports. "Despite some improvement in basin conditions, we expect 2023 runoff to remain below average," said John Remus, chief of the U.S. Army Corps of Engineers' Missouri River Basin Water Management Division. "Soil moisture has improved slightly in some areas, but drought conditions still exist across most of the basin." The 2023 calendar year runoff fore- cast above Sioux City is 21.5 million acre feet (maf.), 84 percent of average. The runoff forecast is based on current soil moisture conditions, plains snowpack, mountain snowpack, and long-term precipitation and temperature outlooks. February runoff in the Missouri River Basin above Sioux City was 1.0 maf., 86 percent of average. |
