...Flooding on the Missouri River 2011...

Gavins Point releases have been cut to 90,000 cfs the weekend September 17-18th, and are forecast to be reduced further for the remainder of the month. Releases will be decreased by about 5,000 cfs every 48 hours, until reaching 40,000 cfs, which is slightly above the typical fall release rate, on or about Sept. 30. To put these releases in perspective, the 80,000 cfs release targeted for early this week will be about half of the volume discharged during the month of July (average of 159,700 cfs). These planned releases are subject to change based on actual rainfall around and upstream of Gavin's Point dam.
