In the fall you'll need to follow the bait migrations. I'll give an examples of this past weekend with a major cold front and a large amount of water coming into the lake.
Friday night we had a very large storm roll through about midnight dumping 5 inches of rain on the north end of the lake. We chose to fish midlake instead of hitting the runoff. They had opened the gates and were dumping water at the same time and the lake was not coming up. I've found the situation to not payoff to run up and fish the shallows.
We had a nasty north wind Saturday morning as the front was passing and our bait had moved from the coves out into the mainlake in 30-60ft of water. Had to get the big net out for bait.
We started out drifting in the middle of the lake where we marked scattered bait in a wide variety of depths, 20-48ft of water. The fish were scattered, but biting when we drifted baits by them. As the morning progressed our bait had moved into a mainlake creek that the wind was blowing into. We set up to drag baits on the ledges of the creek and finished filling the cooler.
For the fall bite, I'd focus on areas midlake and let the bait tell the story as to where the catfish are feeding. If the wind has blown consistently in an area and the bait is shallow, go there. If you have a wind shift, follow the bait as they migrate.
We are dragging baits with our trolling motor and planer boards at .5-1.0mph this time of year. Using planers has almost doubled our catches. It is a pain to run them, but the payoff is worth it. It just requires our customers to be a little more patient and help out a little.
