  • Average Garrison Dam releases declining to address downstream ice

    **Updated to note continued decline in releases toward 16,000 cfs ahead of the forecast schedule.** Fluctuations in temperatures in the Bismarck area have resulted in ice formation on the Missouri River and an ice jam just south of Bismarck. To reduce the threat of flooding, releases from Garrison Dam will be decreased today to an average of 22,000 cfs and tomorrow to 19,000 cfs. Releases may be adjusted as needed over the next several days based on the most up-to-date information.
  • Gavins Point releases increased slightly ahead of colder temperatures

    The U.S. Army Corps of Engineers increased Gavins Point releases from 17,000 cubic feet per second to 19,000 cfs at noon Friday. The National Weather Service’s forecast indicates the lower Missouri River basin will experience extreme cold temperatures for the next 7-10 days. The much colder temperatures have the potential to cause or exacerbate ice formation on tributaries and the mainstem of the lower Missouri River.
