This TWRA release says they so far have confirmed one pod.

How the eff could one small pod get to Chickamauga but with all the angling traffic and boating traffic on Guntersville, not to mention Wheeler and Wilson, no one has seen any on those lakes that could be confirmed?

I'd have to think they're in all the lakes and probably haven't been found yet.

IF you ever get a chance to eat fried Asian carp, do it. It's fantastic. Firm, white and not muddy or mushy like catfish.
