There is no evidence that the Mississippi is flowing into NO. Even if it were, it would flow out into the lake. I have trouble understanding even if the Mississippi is flowing into the lake, how it could influence its elevation much, for the reasons stated. How is that?

If the breach on the Industrial Canal (consult your graphics!) is contiguous (meaning no locks) to the river than the water from the river is flowing in to St. Bernard. Which means that the river is flowing in to the city.

Get it?

I've been across the Mississippi many times but never truly seen an ocean. For me it is hard to understand how that river flowing into any body of water wouldn't significantly influence its elevation--esp. with it being swollen from the torrential rains.
