OK thanks. I remember from reading the New Yorker article posted by LegalTiger that ORCS nearly failed in 1973 and the new structure was built, just didn't see the term "low sill" used.

I think Katrina answered that question for everyone.

I don't believe the answer to this question is as clear cut as you might think.

I agree

However, a morganza failure would be much more catastrophic and the entire nation would never be the same

I was thinking this same thing. Short term the answer is obvious, but if the Morganza fails then life in BR and NOLA as we know it would cease to exist. Long term I'd say it's probably worse loss of life wise to have the morganza fail

I tend to agree more with this however, I think CTF was leaning the other way.

Just heard on 870AM that the river surpassed the 1.5 yesterday all the way to 1.8 and then fell to 1.6. They say that they now may not open the Morganza and that the water would get within 6in of the levee top in N.O. It seems they are definitely scared of opening Morganza.


They do realize we've got some storms rolling in, right?

I call BS on whoever the caller was on that radio show. No way the river can go from 1.5 to 1.8, then back to 1.6 in one day. The BR flow rate is in the 1.3's currently per this [link=(link)]https://waterdata.usgs.gov/la/nwis/uv/?site_no=07374000&PARAmeter_cd=00065,72020,63160,00060[/link].

Not sure where that info is coming from. Check out the conditions for the entire delta as of 0700 this morning.

You seem to be well informed on the situation. Is there any validity to the possibility that they may forgo opening the Morganza Spillway bc they are afraid of losing control?

Just telling you guys what anninvitedbguest said on the radio this morning, he could be full of BS for all I know. Shortly after there was a guy come on from the ACOE who said that the decision to open the Morganza will probably come on Sat. He said their would be a period for evacuation and then a gradual opening of the spillway, but not before Saturday.

It just seems to me that not opening the MS would be an unnecessary gamble. If you open and lose control...by by NO and BR. If you don't open it...you could still lose NO and BR. If you do open it...you could save NO and BR or it might not be enough.

The only scenario that has the best chance of saving BR and NO is opening it and hoping it is enough.

that's just my uneducated opinion.

Big difference is that if you lose control of the river and it changes course BR and NOLA stay dry. And I honestly think dredging could be done to keep the cities working due to the lower sediment deposits.

Loss of life? I'm pretty sure it is. How many people live in greater NO (and or BR)? How many people live in Morganza spillway affected area? Its not even close.

Economic loss? Yes, its still clear-cut. If the Morganza fails, the river doesn't dry up, it just costs a bunch of money to make it navigable again. Its a problem, but it is fixable. Levee fails in NO and this city is fricking done. That is not fixable.

I don't think that is even close to a possibility. The river doesn't want to go there. There is no channel. It's not currently making a channel. That is a huge wide flat area where Old River floods. If not for the basin, there would just be a normal levee there. If the river wants to go somewhere, it's ORCS.

I'm not sure how much rain we are in store for, but even light showers would be a giant sucking arse because they would soak the levees worse than they are now (the outer side here in BR is still dry).

If the storms drop a few inches though, that's going to effect the river level slightly, but it's going to frick ground saturation in places like Brightside much more.
