If Bayou La Battre was under water...that island couldnt have fared well...
The GM&O building at the intersection of Beaureguard and Water Streets is shown surrounded by flood waters caused by the storm surge of Hurricane Katrina Monday Aug. 29, 2005 in Mobile, Ala. Photo taken from the third floor of the Mobile Register.
Dauphin Island wasn't much more than a sand bar when I visited back in the early 1980s. Any storm surge would cover it but then I'd have thought Ivan would have already done that. Katrina would just be finishing the job.
It was nice place to swim though.
