160,000 cfs to continue until mid-August

Once again, substantial rain in the upper basin, as well as the lower river, forced the Corps to bump up their Gavin Point dam releases to 160,000 cubic feet per second (cfs). They now say this new peak flow will continue "well into August". Revisions of the projected flood inundation maps will be released soon. Releases are being adjusted constantly throughout the reservoir system as the Corps tries to make room for new pulses of runoff while providing a steady flow out of Gavin's Point Dam.

Many more levees have broken and overtopped, floodwaters are backing up into new areas and up the tributaries. Several more towns have been evacuated. With rain on top of that, the hydrological projections have been gyrating and changing with each new projection. That uncertainty on top of the certainty that this will go on all summer is a tough combination for everyone that lives or works along the river.

It appeared earlier this week that levee breaches dropped the "crest" enough at Brownville to keep the beseiged Cooper Nuclear Plant from reaching their "mandatory shutdown" river stage of 45.5 feet. Yet after a brief trough, the projection goes up again. Towns in the St. Joseph area experienced the same reprieve.

The Iowa & Nebraska border has become an inland sea pinched off by an hourglass bottleneck at Omaha/Council Bluffs. An inland sea moving downstream but not going away anytime soon.

Dramatic images of Nebraska's two nuclear power plants surrounded by water have helped fuel some wild rumors. There is a section below of stories related to these plants. 

One by one, communities downriver are adding flood protection, or moving out. The uncertainty of what will happen is forcing decisions to take action now. All river traffic has been closed by the Coast Guard from Leavenworth to Gavin's Point Dam.

The tenacity and hard work of family, neighbors and volunteers has been a major part of the story in this midwest region. There is a lot of frustration, of course, and the blame game is ongoing, but mostly people realize the reality of the situation and are acting on their own to deal with it. It's pretty inspiring, and what some of these communities have accomplished in short times is amazing.

A lot is being published on the web on the flood, despite the relative silence in much of the national media. There are several great news feeds, both from official sources and the general public. I've posted many of these in previous posts. Here's a collection of stories and links from the past several days:
