If the levees on the eastern bank of BR fail in a way that can hit LSU, it takes out mostly athletic buildings. Not the campus proper.
False. Elevation of that hill is around 36-38.

You're assuming that the Levee fails entirely from ORCS to the BCS.
The natural levee wouldn't be breached.

The Sheriff of Assumption was on the news this AM and stated that if Morganza is opened that they expect backup into Verret and Belle River to be about a foot higher than the '73 flood. I don't know what the height of the water was in '73 there though?

I went to walk the dog on the levee yesterday and the river was just as high as pectus' pictures.

It is.
Looking at the floodway, it seems that Flat Lake, Morgan City, and Lake Palourde have more to worry about than Lake Verret. But I don't know - I'm just looking at a map.
they are worried about the backwater coming in through Bayou Chene, then Bayou Boeof, flooding Amelia then filling Lake Palourde flooding Morgan City then up into Stephensville flooding them then eventually into Lake Verret, Belle River and Pierre Part.
From what I understand they are sinking barges to block off Bayou Chene but I cannot confirm that at this point.

Did you not read the rest of that post? It isn't like a wave of water is going to come out of the Mississippi flooding the entire world that is below ~46 feet.

My worry is that local levee boards(see Katrina)don't have the ability to actually maintain these structures in times of dire circumstances.
Especially when the below tensas basin levee district commissioner says this.

As expected, the Bonnet Carre spillway will be opened as early as Monday and we expect the Morganza spillway to be opened by the end of next week. The total of this release should remove 850,000 cfs from the system and begin providing some relief for Vicksburg within a couple of days of the release.
ScottieP already said that opening these spillways would show no substantial relief upstream.

Wow. That's one helluva chain-of-events.
I kept hearing how those in Pierre Part were worried, so I see how now. Thanks.

Man, this is some crazy stuff, huh?

Does any one know anything about volunteering to help do something? Fill sand bags or whatever. I don't care, I just feel like I'd rather be doing something instead of just sitting around waiting for something to happen.

If everything works from the ORCS south to Venice, there won't be a need for massive efforts to help sandbag...unless you want to drive to Morgan City.
These people who live or own property in a floodplain should be aware of it already and have the proper precautions in place.

19.5 ft at Bonnet Carre does not equate to 19.5 ft at New Orleans. River levels decrease further downstream you go
Thanks for the link you provided.
I understand that the Carrollton Gage (New Orleans) is 25 river miles below Bonnet Carre and that the river levels decrease as you go downstream. I was just surprised that it was already that high at the spillway.

I crossed it this afternoon. Water is coming into the forebay but it is still a good ways away from the structure. They appeared to be doing work to the guide levees on the Morganza side and 2 gates were up. They still had a herd of cattle on the floodway side.
It just took down my duck blind.

The water in Stephensville is already higher than normal, they are pretty much certain to flood, but they usually take a good bit of water just on a higher than normal Spring Rise...this seems like it could be a little bit more than higher than normal....but we'll see
Honestly I dont think MC proper has anything to worry about....there maybe some parts of MC that floods, but if if does it will be because of the backwater, not just what comes down the River.

I agree. I have worked with just about every district since 2004 in South Louisiana. They are OK when it comes to running the day to day operations of the district, but the technical aspect is when it gets dicey. Having a lawyer or salesman do an engineer's job turns into catastrophe.

Lots of lawyers and salesman in SE LA think they are more than qualified to do anything on earth.

I have heard nothing of anyone sinking barges, but I'll look into it.
