Click here. Good images of flooded areas, before and after along with levee breaks.

If you go to http://maps.google.com you'll find a Katrina link in the upper right corner that gives an aerial photo that can be panned and zoomed into. Pretty nice job.

Thanks all for the links. Before and after was the best.

Small town where I was starting high school went through a flood in 1984 and to this day the town still doesn't look the same, there are empty lots between houses where people didn't rebuild. I think NO will never look the same. Hopefully the people in charge of the rebuild will have the sense to fill in the low areas.
