What if Hurricane Ivan Had Not
Missed New Orleans?

New Orleans was spared, this time, but had it not been, Hurricane Ivan would have:

• Pushed a 17-foot storm surge into Lake Pontchartrain;
• Caused the levees between the lake and the city to overtop and fill the city “bowl” with water from lake levee to river levee, in some places as deep as 20 feet;
• Flooded the north shore suburbs of Lake Pontchartrain with waters pushing as much as seven miles inland; and
• Inundated inhabited areas south of the Mississippi River.
