Camille had 200 mph sustained winds at landfall with 220-250 gusts and a storm surge over twice this one.
The way the wall rebuilt at the last moment and the path over the river delta weakened it fortunately.
It's very unclear whether Camille had a larger surge than Katrina. It's possible Katrina's will be larger.
Remember, there hasn't been a single report from Pass Christian where the surge would have been highest for Katrina(and where it was highest for Camille.
Everytime I hear about Camille its stats become more powerful after every re-telling. Next we know its barometric pressure was 700 and peoples heads litterally popped like balloons from it.
