INUNDATEDHurricane Katrina breached New Orleans and St. Bernard Parish’s defenses in multiple places on Aug. 29,2005, and “filled the bowl” with seawater pushed in by the storm. On Sept. 2, when the floodwaters arebelieved to have reached their maximum height, the U.S. Army Corps of Engineers determined thedepths in various areas. It took more than a month to pump all of the water out, in part becauseHurricane Rita’s storm surge pushed new floodwaters through the breaches in late September.
