The first 5 or 6 miles below Guntersville Dam on Wheeler Lake has some great catfishing. The former world record blue catfish came from Wheeler and I suspect the new record is swimming in there now. Jugs are very effective there and perfectly legal. I caught several hundred pounds of catfish there last year using jugs in a couple of weeks. Every day I fished for them I completely filled my livewell with catfish in under 4 hours.
