Good luck down there!
The walleye in the Cumberland remain a mystery most of us. There are a few who have found a consistent bite, a few... I have not been very successful with the elusive fish but I'll pass along what I have learned.
Trolling a nightcrawler behind a spinner (crawler harness), on the 3 way rig with 1 to 1 1/2 ounce wt seems to be the trick. Keep the speed slow, under 2 mph. Can't help you with location but the Hot Spot map and some old posts might steer you to a starting place. They are after the same bait fish as the stripers so if you find the stripers (or the striper fishermen), the walleye should not be far.
Sorry I cant help more, let us know how you do. If you can find 'em, they'll be hungry!
