When I was living and fishing a lot in far S.Texas, I would always hear from the locals that no matter how much devastation a hurricane brought to land, it was very good for the bay system. The tidal surge and all the rain was sort of like flushing a toilet. Cleaned out the bays. Although this made sense, I never really bought into it. Since Katrina has totally devastated the land mass here, there have been some interesting things on the water. A manatee was seen in the Rigolets last summer. Didn't believe it till I saw a pic in the paper. A 200+ lb. tarpon caught in Lake Ponchatrain. Also in the paper. I have seen dolphins in the canal system where I live for the very first time. We now have a resident racoon, which prowls my dock at night, never seen before. Squirrels in the trees, for the first time. So maybe, there is some benefit from the hurricane, even if it's not a benefit for human beings.
