Skip to comments.Mississippi River flooding in New Orleans area could be massive if Morganza spillway stays closed

If the Morganza Floodway is not opened to funnel 300,000 cubic feet per second of water from the Mississippi River into the Atchafalaya River basin, the additional water could cause levees to fail along the river from Morganza to Plaquemines Parish, including all of the New Orleans area, resulting in as much as 25 feet of floodwater, according to a map provided to state officials by the Army Corps of Engineers on Tuesday.

Stuck on repeat?
Have they got the Old River Control Structure secured? Seems to me they had a real close call a few years ago where it almost washed away changing the course of the Mississippi for ever.
How does Obama feel about black people?
Just wondering. When will that great philosopher/conscience of the nation, Kanye West, weigh in on the racial feelings of the president? He likes to weigh in on same at times of disasters happening in areas with significant black population.
Who is the present mayor of New Orleans, any changes in the last couple of years?
True dat. Obama is going to let New Orleans drown because he hates black people.
Jindel says it isn’t a matter of if these will be opened..but when.
The Atchafalaya River will capture the Mississippi, its only a matter of time. Building the levees higher, diverting through the Morganza, etc., etc. are just going to delay the inevitable for a few more years.
In retrospect, I don’t understand why Kanye West was even on that charity telethon after Katrina. Is a rap singer really a legitimate entertainer in the first place?
Maybe I’m behind the times, but I thought rap was obscene, and full of violent imagery. I thought those “performers” were in the shadows of the entertainment business, not unlike the way pornography is in the shadows. Yet it seems that rap has really been forced into the mainstream. Just an observation.
I’m not bullish on New Orleans long term.
My problem is they are blowing holes in the dams and such to flood farm land. What do they think that’s going to do to our food sources and prices? It sounds hard hearted I know, but, you either let the towns flood and it affects them more or less alone. Or you flood farm land and it affects everyone. With the possibility of a food shortages.
It is it bit strange that they would write a “what if” article since it is well established that the Morganza will be opened.
And not only will the Morganza be opened, but I would not be surprised to see levees below NOLA dynamited.
You know damn well if the SHTF in New Orleans, Jindal will get all the blame.
I concluded from what I was reading a couple days ago that they would open the Morganza. This article contains the justification.
It would be much more expensive to intentionally flood New Orleans than it would be to intentionally flood some farmland.
They reallly have no choice. Very disturbing how these flood waters are affecting the whole stretch of the Missippi and it’s tributaries. Doesn’t look like many will escape the affects, one way or another. Including the nation as a whole.
The river has been changing channels now for a couple of centuries. Eventually it comes out at Morgan City ~ and that's a certainty.
Did you see what the OHIO FORK (the largest Mississippi tributary) did at the end of the last Major Glaciation? It cut clean through the limestone floor to connect with its upper reaches ~ you need to read about the TEAYS river to get a feel for it.
The Ohio is actually larger than the Mississippi (in CF/M) where the two join.
Fortunately for the lower reaches of the river, the flood control features built over the last 80 years along the upper reaches seem to be working decently so the flood should be over sometime this year rather than next year!
IMO, it's a troubled city in a bad location.
Historically, flood zones had the best cropland ‘cuz natural organic nutrients would get dumped there. Working with it can give good results.
Our modern approach of containing and preventing floods is the unnatural solution leading to questionable results.
The farmland will recover fast. The cities won’t (though maybe it will be a wake-up call to DON’T BUILD CITIES IN A FLOOD ZONE).
The S has already HTF in New Orleans. The place is a mess.
Look at the Japanese. They’re not sitting around complaining. They are working to restore their country. Compare the Japanese with the folks in NOLA. They’ll still be whining 5 years from now.
it was okay for Texas to burn,for Nashville and now Memphis to be flooded, and all the thousands of acres of mid America farm country to be devastated by tornadoes and now floods, but gee the Chocolate City?....I’ll bet we’ll see National Guard bailing by bucket in the near future...maybe we can spend another $90,000 on EACH N’Orleans resident like we did following Katrina....
I wonder if Sean Penn is already there with his Dixie Cups.
Best you put big holes in them now so they'll drain off before August!
Some of those area’s that are flooding I don’t think have flood in decades. But, I suppose your right. I just saw a farmer crying the other day because his farm land is underwater. I do feel badly for the farmers. The work so hard and most of them make so little.
Jindal has already warned people to get ready to move out.
I can easily see the idiots in New Orleans sitting on their lard butts waiting to be rescued and saved by the gubmint.
I wonder if the Super Dome is up to a repeat of 2005?
Where’s Brownie when we need him?
Won't matter, it will still be his fault.
So why, you might ask, are there people living in New Orleans and Cairo, and that would be a good question. Cairo is in a long term state of serious decay and depopulation. Paducah and Evansville, far safer from the river's course, have taken on the burdens of human commerce in the Delta.
But there are less votes damaged when you flood farms.
NOt just a “flood zone”, but a “Flood Path”. New Orleans is literally the bed of the Mississippi lower delta. There’s no excuse for building below sealevel!
I suppose but, how hard is it to control something like water? The end results can be good or bad. My guess is there is now good way of predicting that. I feel terrible for the people that are caught in this. What a mess. The thing about building cities in flood areas is, some of those areas don’t flood very often. I would think you could say the same thing about earthquake zones. Unless it’s an area that gets flood pretty often, like maybe ever decade, I’d say just stay put but, be prepared and try to get flood insurance if you can.
I don’t minimize the pain and expense of abandoning those sites but I agree, when you look at the plain facts it seems like a no brainer. Especially Cairo. According to Wiki the population is only 2,831. Come on.

False River Background
There is a huge misconception about the frequency of flooding in New Orleans. For example, I own a few houses in New Orleans, one of which has been in the family for 80 years and it has never flooded. New Orleans does not flood often, but it does flood big when it does flood.
Other parts of the city have flooded in 1965 and 2005 due to hurricanes which makes New Orleans much less flood prone than areas in the upper Mississippi and Missouri Rivers.
One more time, the Delta is the main fancy bean growing area in the world. Mexico has a contract on about 90% of the bean crop there. This is their meat.
By protecting the Delta Bean Crop we keep 35 million Mexicans in Mexico and I think that is an excellent idea, don't you?!
You have obviously thought about this much more thoroughly than I have. Many trade offs to be considered.
I can't believe you posted that.
Does she have an album release soon?
Oh, a Louisiana co-owner.
I just wondered if that "whip crack" Ray Nagin was still there.
Louisiana - Half under water, the other half under indictment.
In the context of this thread, it's not just cities like New Orleans that have to be weighed against farmland. You have to factor in the majority of the Lower Mississippi River Industrial Corridor (including the Shell Norco refinery) as well.
Cairo is two-thirds black. End of case.
Nagin has been busy writing his memoirs.
