  • John Day Dam storing water to minimize lower Columbia River flooding

    Federal water managers are changing release and storage schedules at several Pacific Northwest dams because of a late season and strong atmospheric river that began June 9. Significant amounts of rainfall have fallen across the Columbia River Basin filling reservoirs and rivers.

  • Oahe and Big Bend Dams supporting temporary power needs

    Beginning today, releases from Oahe and Big Bend Dams in South Dakota will be increased from a daily average of about 15,000 cfs to about 36,000 cfs, downstream conditions permitting. These releases are aimed at providing additional power generation during a winter storm moving across the country over the weekend. "The U.S. Army Corps of Engineers, Northwestern Division is working with the Western Area Power Administration much like last February," said John Remus, Chief of the Missouri River Basin Water Management Division. These actions will not effects the overall system storage, and will not change the System releases from Gavins Point Dam. We do not expect these release changes to remain in effect for more than 24 hours.

  • 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.

  • Fort Peck releases to change slightly

    Releases from Fort Peck dam will be increased from 9,000 cubic feet per second to as much as 11,000 cfs to address conditions immediately downstream of the dam. Releases will begin increasing on Aug. 14, or once planned maintenance projects at the Fort Peck power house are completed.

  • Gavins Point releases to remain steady through August

    Below-normal precipitation in Montana and Wyoming during July resulted in slightly below-average July runoff in the upper Basin. The 2020 calendar year upper basin runoff forecast, updated on August 3, is 30.9 million acre-feet (MAF), 120% of average. Average annual runoff for the upper basin is 25.8 MAF.

  • Releases from Fort Peck Dam to decline during maintenance work

    Releases from Fort Peck Dam will be reduced from 11,000 cubic feet per second to 8,500 cfs on July 28 and then increase slightly to 9,000 cfs on July 29. A Power Plant maintenance project originally scheduled for June was rescheduled for late July. The project will require outages on Units 1, 2, and 3 to support testing on Unit 2.
