Posted on 06/23/2011 10:20:38 PM PDT by justa-hairyape
On June 23, 2011, the U.S. Army Corps of Engineers drastically increased the amount of water released from the Gavins Point Dam into the Missouri.
On June 23, 2011, the Nebraska Emergency Management Agency announced that flood waters along the Missouri River at Plattsmouth, Nebraska, south of Offutt Air Force Base, surpassed previous flood records set in 1993 when they reached 36.03 feet. Nebraska City, Nebraska also surpassed 1993 levels with a record 27.79 feet.
Intimidating, perhaps, but not surprising to the Army Corps of Engineers who announced Tuesday, June 21, 2011, that they would increase the amount of water released into the Missouri River from Gavins Point Dam near Yankton, South Dakota from 155,000 cfs, or cubic feet per second, which was the amount they originally planned to maintain for the rest of the summer, to 160,000 cfs on June 23, 2011, anticipating an average increase of four inches in flood water levels.

FYI - That levee is upriver from the Cooper Nuclear Station. Looks like it was the eastern bank of the Missouri that has busted out. They have evacuated three Missouri counties. Have no idea what this will mean to the water levels at Cooper.
The chairman of the Nuclear Regulatory Commission is coming to Nebraska.
The visit by NRC Chairman Gregory Jaczko has to do with both of the states nuclear power plants being threatened by the floodwaters of the Missouri River.
Jaczkos visit is scheduled for Monday.
Above article was posted on June 20th. Do not know if those interstate sections are still closed. Now with the new levee break near Brownville Nebraska they supposedly were going to close parts of 136 on the Missouri side of the river.
A Missouri River levee three miles north of Brownville, Neb., failed Thursday night, triggering evacuations in Atchison County, Mo.
According to early assessments, the breach posed no threat to the Cooper Nuclear Station near Brownville.
The breach, which came about 9:20 p.m., will not affect the city of Brownville, said Renee Critser, the Nemaha County emergency manager.
Wouldn’t a break on the other side of the river and upstream from the nuke plant help it?
Now study the ground around the river bed. Nuclear plant is 3 miles south of Brownville. Leeve breach is 3 miles north of Brownville. Breach appears to be out to the east direction. Only Missouri towns evacuated. Now, back to the map, if you zoom out while still keeping the colors still mostly brownish, you can see the old flood plains near the nuclear plant. Successions of flood plain lines go out very far to the east. There appears to be three distinct flood line markings.
Now have a look at this previous flood that happened back in 1993 when dikes and levees burst and the same plant flooded and actually suffered minor damage.
See how flooded the other side of that river was back then ? At any rate, just playing around with the web and seeing what can be done with today's searches and links. Wonder why the MSM is ignoring this stuff ?
Wonder why the MSM is ignoring this stuff ?
Cuz we’re a red state!
Concerning the media, I do not even remember hearing about the earlier flood in 1993 when the nuclear plant actually experienced minor damage. Wonder who was President then ?
Scaremongering ? Tell that to the head of the NRC. He will be visiting Cooper on Sunday and Fort Calhoun on Monday. And apparently you have completely missed the story from 1993 where levees broke and Cooper was flooded before they had enough time to prevent damage to the Nuclear Plant. So whether it survives this flood or not, they still have problems.
“Have no idea what this will mean to the water levels at Cooper.”
No effect on the plant I have read today.
Levee broke today.
Yep. Around Fort Calhoun. The water berm that was surrounding the plant burst. Trying to figure out what is going on, but it appears that water is now up to one of the buildings (auxilary). The claim is that these buildings are water proofed up to a certain height. We shall see I guess. The big problem is Cooper which is still running. The situation could snow ball out of control very quickly. This is the biggest Missouri flood ever recorded by modern man. We will be dealing with this water through August. And the entire Missouri river valley has been hit by heavy rains all weekend. In fact heavy rains hitting again right now. Omaha just got heavy rains and they are currently pumping flood water into Missouri from the rains Saturday morning.
Family back home said we might not be able to get there for the Fourth. No good way to get across the Missouri.
Fort Calhoun is 40 or so miles from my parents house. Not a good thing.
It didn’t break. Someone won’t be driving a skid loader in the near future.
I understand the main I 80 route through Omaha is still ok. And I thought 680 over and across through Blair was still ok?
My guess is you want to be up wind. In fact, some may not be able to get up wind because they cannot cross the Missouri traveling east to west. Access roads are a mess.
We have new reports now about what happened at Fort Calhoun. See below links. The breaking of the levee surrounding the plant knocked out the diesel generators or what ever on site power they were using. They had to switch to batteries while they switched to off site power. They are now running on off site power. Darn good thing they ran that line ? Plan is to repair the levee dam. And note - Fort Calhoun is not running. Just holding a lot of dirty rods.
Rain should be leaving later today until next weekend. Should give them sometime to assess the damage.
Oh, and the GE/NRC spokesman said these are not the droids you are looking for.
Highway 30 through Blair is shut down, and I 29 north to Onawa is closed.
My parents live north of Omaha, and my mother in law north of Sioux City. We can get to either one, but it will take some doing.
They can head west if needed. That is up wind for the most part.
I heard from friends near by that the diesel generators are knocked out. Why they build those in the basement I will never know. The new line is good, but with all the storms that is a thin life line.
They should have good weather for a few days. Some reports claim water is seeping into buildings. Nothing confirmed on that yet.
The net is swimming right now with reports of a “10 Mile Mandatory Evacuation Area” being implemented right now.
Anyone able to confirm this or dispel this as a rumor?
FYI - The Army Corps of Engineers has stated that there will be consequences for people spreading false rumors. Just posting the above link for informational purposes and because you asked about it.
“Anyone able to confirm this or dispel this as a rumor?”
My daughter would let me know if that was true!! It’s not.
If people want to know if something crazy like this was happening, either of these 2 sources would be all over it:
Are you implying that wind blown radiation is likely.....
At any rate, some of the videos of Fort Calhoun are very depressing. They must have a couple dozen sump pumps moving water out from sandbagged buildings and structures. And this flood is supposed to last through August.
It very much appeared you were saying radiation was probable / likely. And we all should be looking to be up-wind.
Thanks for clearing that up........
