Earlier optimism about improving runoff in the Missouri River basin proved short-lived, as August brought a return to drought conditions. The Corps of Engineers announced September 7 that winter releases from Gavins Point Dam will be just 12,000 cfs., as part of overall water conservation measures called for in the Corps' Master Manual for Missouri River operations."Reservoir inflows in August were much lower than average," said John Remus, chief of the Corps' Missouri River Basin Water Management Division. "We expect below-average inflows into the system through the rest of 2022. Based on the storage in the system at the September 1 storage check, winter releases from Gavins Point will be 12,000 cfs. for a second year in a row."While July brought some much-needed moisture to the Missouri River Basin, the month of August showed a return to the warm and dry conditions seen in the basin over the last two seasons, the Corps said. August runoff was 0.9 million acre-feet (maf.), 62 percent of average above Sioux City, and 0.6 maf. or 49 percent of average above Gavins Point Dam. The portion of the basin that drains into Oahe Reservoir was particularly dry, only experiencing 10 percent of its average August runoff. |
