  • ​Releases from Gavins Point Dam to decrease

    “The upper basin runoff forecast has been reduced by about 1 MAF due to the recent dry conditions as well as the National Weather Service’s climate outlook, which is indicating that the remainder of the summer will be warmer and drier than normal. However, the 2020 calendar year runoff forecast remains above average, mostly due to the very wet soil conditions during the early months of the year. Most of the mountain snowmelt runoff has entered the reservoir system. Remaining summer runoff will depend on rainfall events,” said John Remus, chief of the U.S. Army Corps of Engineers’ Missouri River Basin Water Management Division. “As a result of the reduced runoff forecast, we will reduce Gavins Point Dam releases to 30,000 cfs on July 7,” Remus added.
