Here's a Big Muddy News blog post with the latest information on the Corps dam release plans (including the press release Vicki posted above)-
http://bigmuddynews.blogspot.com/2011/07/corps-releases-flood-drawdown-schedule....Basically, releases from Gavin's Point dam will drop from 160,000 cfs to 150,000cfs by Monday, August 1. They will remain at that level until mid August. Then they will step down 5,000 cfs per day with a target of 90,000 by the end of August. It takes a week-ish for changes at Gavin's Point to reach KC, but with all the flooded land adjacent to the river draining, it's hard to say what the actual response will be.
It will hold at 90,000 for a couple weeks, then get down to 40,000 by Oct. 1.
They've figured above average rainfall into this, but if there is a bunch of rain, especially above the dams, this schedule may change. If there's a bunch of rain below the dams, there will be higher levels below KC regardless.
The important thing to realize is that in the Missouri River below KC, the river level generally has less to do with what comes out of the dams than how much rain we get in the Grand River, Kansas River, Nishnabotna, etc.
