Releases from Fort Peck Dam to decline during maintenance work

Missouri River Water Management Division
Published July 21, 2020
System storage is 61.8 MAF and has likely peaked (upper right quadrant).
Last week the National Weather Service updated their August (lower right quadrant) and August-October precipitation and temperature outlooks.
Mountain snowpack has essentially melted.
Fort Peck releases will be reduced from 11,000 cfs to 9,000 cfs on July 28 for about 2 weeks to conduct maintenance and testing on hydropower units.
Refer to the 3-Week Forecast for the most up-to-date System information – pool levels, inflows and releases.
The Gavins Point release is 30,000 cfs. We expect releases to remain at that level for the next several weeks.

We expect releases to remain at that level for the next several weeks.

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.

“The lowered releases should not impact reservoir elevations at Fort Peck as inflows from mountain snowpack are also forecast to decline,” said John Remus, chief of the U.S. Army Corps of Engineers’ Missouri River Basin Water Management Division.  Fort Peck releases are expected to return to 11,000 cfs on August 8.

The release changes will not impact downstream dams with releases from Garrison Dam forecast to remain at 28,000 cfs and releases from Gavins Point Dam forecast to remain at 30,000 cfs through August. Releases from other projects fluctuate for hydropower production.

Each Wednesday, or more frequently if needed, the Missouri Basin Water Management Division releases a detailed three-week release forecast. The detailed forecasts include projected reservoir elevations, inflows and releases from each of the mainstem dams. http://go.usa.gov/xVgWr.
