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.

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. [Read More]

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 [Read More]

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. [Read More]
