Releases from Oahe Dam reservoir increasing to 65,000 cfs tomorrow; More minor flooding expected in Pierre/Fort Pierre

The US Army Corps of Engineers will increase the release rate of the Oahe Dam to 65-thousand cubic feet per second tomorrow (Thurs.).

At the Corps’ annual fall meeting today, power production team leader for Missouri River water management Mike Swenson says releases from Oahe will remain high through next month.


Swenson says they hope to evacuate the water from the Missouri River System’s annual flood control zone prior to next year’s runoff season– but it may not be possible.


He says a 10 day extension of the navigation season below Gavins Point Dam gives them a little extra time to evacuate water from storage in the upper reservoirs.


Swenson says they can push about 1-million acre feet of water out of the Missouri River System after it freezes over, but they have to be cautious about ice jams causing blockages downstream.
