Industrial Canal levee, which was thought to the one of the weak links has been overtopped and water flowing into the city. Not a breach at this time.

If memory serves me, once water starts flowing over a levee, it almost produces a "cutting" effect that literally starts carving INTO the levee, making it more likely for a larger hole to develop, which can undermine the whole structure.

Also, I think you mentioned in a prior post that the pumps that drain the "bowl" of New Orleans were sized to drain water associated with a few minor leaks of lake / river water into an otherwise "dry" bowl. When a hurricane is parked overhead for 15 hours dropping 10 inches of rain, you're not starting with a dry bowl.

Not over by a long shot.
