©DigitalGlobe image of the flooding in New Orleans, LA, August 31, 2005. Water from breached levees and Lake Pontchartrain continued to flood into New Orleans and the surrounding area on this date. About 80% of the city was under water up to about 25 feet (7½m) in depth. Mouseover the image to see the same scene from March 2004 for comparison.
