Ok, so we have waist to chest deep water at Laffite, which runs from 13 to 16 feet above sea level.
We have water running "upstream" in the Vermillion River at Lafayette, the lowest point of which is 20 feet above sea level.
Two sources putting surge around New Orleans at 20 feet, give or take, fair enough?
The surge gets deeper over towards the point of landfall, but for now, let's just stick with 20 feet.
Take a look at this:

Incident of National Significance?
I know you all think I'm losing it..lol..and thank you kindly for taking the time to show me where you are speaking of- but I found a completely different Lafitte, LA north of Lafayette..near a lake called Bayou du lac..that's why I was confused.
Do I seem punch-drunk yet? ;)
