The rise in Lake P isn't the issue. The issue is the head. How high inside versus how high outside.
The counter to that is sheet piling under the repair. If it's there, the fill will hold, if not, it won't.
Keep in mind that dry ground isn't related to the head. The water table exists underground as if the land wasn't even there.
On a related note, how to you clean a water supply system that has been compromised as New Orleans' has?
Treatment can clear the major supply lines, then you need residents to run the water under a Biol Order foir a few days to clean out the "last mile".
All well and good, but that's the procedure for bioligical contamination. This system hs been compromised with chemical contamination as well.
Big job, but as posted earlier, New Orleans recovered from 5 to 7' flooding during Betsy in the 60's.
Betsy wasn't as extensive obviously. But I moved to New Orleans in summer, 1968 and my first high school was selling magazines door-to-door throughout New Orleans. I went all over that town, through the projects, etc This was 3 years after Betsy and I saw no residual evidence of hurricane damage that I noticed. Not sure how much time I spent in the 9th ward however, which is where the worst of it was.
I think the rebuilding will happen much faster than the talking heads are saying at least for some areas. The West Jefferson / Harahan area expects to have power in 2 weeks according to my brother.
Understood, I don't think the canals are very deep.

That is way beyond my pay grade. But I will say that mother earth has been a self-cleaning organism for millions of years - according to the Darwinists. LOL!
It seems that the sobsisters with microphones have moved on to threats of contamination, since other threats are more under control.
