Waves today crashed high against flood walls and the city's rebuilt levee system survived its first hurricane in three years, but Hurricane Gustav did expose weaknesses.
While an Army Corps of Engineers spokesman says "all the walls have performed as they were designed to," Gustav's storm surge entered New Orleans through navigation channels in the east and washed over the Industrial Canal. The corps is spending $700 million on a barrier at its mouth to stop surges. But the barrier won't be in place until at least 2011.
Another major weakness in the flood protection system is in the area known as the West Bank, where water will continue to rise into the evening hours.
