  • Corps steps down releases from Gavins Point Dam to winter release rate

    The U.S. Army Corps of Engineers began reducing Gavins Point releases to the winter release rate on December 2. The releases will be stepped down at a rate of 3,000 cubic feet per second per day until they reach 20,000 cfs on December 11. Releases are expected to remain at or near 20,000 cfs for the remainder of the winter. Gavins Point Dam winter releases normally range between 12,000 and 17,000 cfs.
  • 2018 Edition of Missouri River Master Manual now available

    The 2018 edition of the document governing how the six dams on the Missouri River will be operated was made available to the public today. The 2018 Missouri River Mainstem Reservoir System Master Water Control Manual, or Master Manual, reflects current data and conditions relative to data collection, reservoir modeling, long-term runoff forecasting, reservoir regulation planning, and communications. The 2018 manual also includes cumulative regulation data, such as runoff and reservoir data, through 2017.
  • Releases from Gavins Point Dam to begin declining Sunday

    Water releases from Gavins Point Dam will be reduced Sunday, Nov. 25, from 58,000 cubic feet per second to 55,000 cfs, the U.S. Army Corps of Engineers announced today. Releases will be incrementally reduced over the next few weeks to winter release rates ahead of the river’s icing-in in the upper portions of the basin.

  • Continued reservoir releases in preparation for 2019 runoff season; Public meetings set for this week

    Higher-than-average releases from all Missouri River Mainstem System projects, including Gavins Point, will continue through November. To ensure all stored 2018 runoff is evacuated prior to the 2019 runoff season, most of the releases must occur before the river ices over in reaches predominantly upstream from Lake Oahe. The 2018 runoff forecast looks to be the third highest since record-keeping began in 1898. Runoff in the unregulated reach from Gavins Point Dam to Sioux City was 1.7 million acre feet for September and October, which is the highest in 120 years of record-keeping
  • River operators increase flows to welcome returning chum salmon

    Sometimes being underwater is a good thing, especially for Columbia River salmon nests, called redds. This fall, federal agencies are increasing Columbia River flows below Bonneville Dam to ensure the redds of spawning chum salmon stay covered with water. The agencies have conducted these “chum operations” every fall since 2000. Beginning Nov. 2, the river will be held between 11.5 to 13 feet above sea level to ensure chum can spawn at the mouth of Hamilton Creek in the Columbia River Gorge. For chum operations to occur, water is released from reservoirs as far away as Hungry Horse and Libby dams in Montana, more than 850 river-miles upriver from Bonneville Dam. The water is then captured and released as needed to create spawning flows that keep the redds underwater.
  • Reminder for Missouri River basin fall public meetings; some dates rescheduled

  • Partners united for salmon, steelhead and lamprey extend Columbia Basin Fish Accords

    States, tribes, and three federal agencies continue to work side by side for the good of endangered salmon and steelhead as they extend the historic Columbia Basin Fish Accords for up to four more years. The original agreements, signed in 2008, provided states and tribes more than $900 million to implement projects benefitting salmon, steelhead, and other fish and wildlife, and $50 million for Pacific lamprey passage improvements at federal dams on the Columbia and Snake rivers.
