Obviously this is going to be different because of the river width, depth,bottom contour, etc. Does anyone know how accurate these estimates really are, or are they simply blind guesses at this point as it pertains to flow?
No, flow (cfs) will not be different dut to cross-section of the channel. Flow remains the same, unless water is added or taken away..... Not sure about the accuracy of the estimates. But the whole system is modeled by what I assume are sophisticated models. I also think there are many assumptions that go along with the models' estimates that are not included in articles.

the southern portion of concordia always gets backwater when the river comes up. The area around Larto Lake floods when the river comes up. Something is not making sense why are people getting ready to move all of their shite if there is no threat.

Yea, people are freaking about something that if nothing goes right will be catostrophic. If everything does, we add some water in the spillways and the Atch...Morgan City sees some minor flooding.

No, it will not reduce the water level but lack of rain will positively affect integrity of levees and reduce time table for drainage.
This. Nothing really drains into the Mississippi in SELA, so rain doesn't have an effect on the hydrology.

Because no political leader wants to lose their job over this...they are going to give you the absolute worst, when the probability of that happening is low.
All this region needs is another Ray Nagin on our hands and we're the posterchild for stupid decision making.

I was thinking about this earlier. Could you imagine people having to be rescued from rooftops in Louisiana...again. People need to be smart and evacuate when told to do so. Believe me, they will tell you when it's time.

The engineers are the ones giving the forecasts of record-high river levels.

Just because it isn't high now doesn't mean it isn't going to be. The water is coming. It's a certainty...unless the New Madrid fault acts up again.

Exactly. Telling people to evacuate now would be like clearing NOLA out with a storm in the Mid-Atlantic. People who knowingly live in a flood zone should already have made preperations just as we're supposed to every hurricane season.

And the political leaders and community leaders are the ones saying everything from Jackson MS to Houston is going to flood if the billions of dollars in flood protection just disappear or all fail tomorrow.

I obviously don't understand anything about the spillways further up the Mississippi River in LA but my brother until recently lived really close to the major spillway near Norco that they've opened up a few times in recent years. Are the spillways around BR much different than that one? That one works wonderfully. Why would the others have so many problems by comparison? It seems like you could just open the one near Norco and at least one upstream of BR and BR would be fine. What did you guys do in 1993? There was a hellacious flood on the Mississippi. Did that not cause problems in Louisiana?

The big rise has not reached us yet. It is still a matter of a few days or a couple of weeks, depending on where you are, away from us.
If I lived in the West floodway (Avoyelles Parish) I would start to pack up valuables and things that could not be replaced. The call to pull out, if it comes,will likely be with very short notice, so you need to be ready. I might say the same about some of the land around Vidalia, as I do not think that efforts to raise the levee there will be successful. Funny thing is that if the levee at Vidalia is topped or it is breached,it might save other folks down river.
Again, I don't think it will come to that, but the only positive things you can do now is to pray and pack.

So if the river were to jump it would do it at the ORCS, dont they have to use that to send the water to the Morganza?
Posted on 5/4/11 at 5:37 pm to Golfer
Yes, I agree, everyone should not bank on a catastrophe happening. But we should regard that this year IS different than in years past. The river is going to rise higher than people are used to in typical spring floods.

Damn. It still has a ways to go.

Just heard on the local Natchez radio station they have lowered the expected crest on the 22nd by 1 foot, which might not sound like much but every little bit helps I guess.
So now instead of 65 ft its now 64 ft.
