for new orleans surrounded by water during that event and possibly this event is pushing all of the water into the lakes and pushing it it to the city. they have done a lot of work with a lot of new gate complexes that keep the water away from the center of the city. >>shepard: lake pontchartrain is here and the water came to the back side of the city, from the east side, and pushed in. if this storm came in, say, west of new orleans, you would get a more traditional counter check wise storm surge and in the bayous where you had all the verge face and the growth, all of this march land and barrier island, over the last 50 years from stuff we have done and stuff that mother nature has done, that is largely gone and you have not had an event where the water pushed in here with a storm to the west with the counter clock wise surge just push right into the city.
