You'd probably be fine, while the river will be 47 feet, that doesn't mean everything around will be flooded to 47 feet if a levee breaks. Once the water starts spilling out of the levee barriers, it will take up all of that open space, which will lower its overall height.

one thing to remember is that on the west side of the river the levees are lower, so if anything does flood around here it will be Port allen flooding before we do.
thank you Heuy Long

And you must have some pretty awesome programs to be able to calcuate stuff like that. Very cool!!

Yea, but if the levee breaks, then the east side is screwed

If the levee breaks, the water will spread out. The problem is that the water will keep on coming until the river goes down. June? July?
To give you some idea how much water is moving down the river, at 1,500 cfs (the Corps targeted maximum discharge in BR), I've converted the units to acre-feet (the amount of water that will cover one acre, one foot deep).
~34 acre-feet per second
~2,066 acre-feet per minute
~123,967 acre-feet per hour
~2,975,207 acre-feet per day
That's enough water to cover 465 square miles, 10' deep, every day.

that is almost unreal to think about

Well, it wouldn't ALL go through the levee breach. The vast majority would still go down the river. But it'll keep on coming for 6 or 8 weeks!

Obviously, but I keep seeing images from Katrina with any kind of breach

A BR (or NO for that matter) levee breach here would be far, FAR worse to regain control over than Katrina.

The only reason water stopped coming into the city through the 17th St and London Ave outfall canal breachs is because the water level dropped in Lake Ponchartrain (combination of falling tide and wind shift).
The Salton Sea, in southern CA, was created by a breach of an irrigation canal headgate on the Colorado River. The Southern Pacific Railroad built a trestle over the breach and dumped rocks into the hole for months, trying to stop the flow. The first trestle got washed away by the next Spring flood, so they started over again. It took almost two years to stop the river from pouring out into the Imperial Valley.
A Mississippi River levee breach during this Spring runoff is going to make the news media jizz their collective pants.

This could be turrible

Lexington and UC Club subdivisions should be concerned. There is a huge bend in the river close to these. I am concerned opening Morganza is not going to help enough.
Have you heard anything from anyone reliable to make you think this?
I live in that area, and it seems like its hard to get information about the levees there.

No, I haven't. I can't get any information about the levee heights either. I am wondering if they are below the min. 48' height of the levees closer to LSU. Any info would be appreciated.
