I recently had a humbling couple of days on South Holston Lake, and I want to hear some of the ways you guys target fish behaving how the ones I found were.
South Holston is an extremely deep lake, the boat is rarely in less than 30 FOW when you are fishing any bank (IF you are fishing a bank). It has a lot of limestone influence, so it looks really clear but probably isn't much more than 6' vis, it's just blue. The lake has gizzard shad, threadfin shad, and alewives. The smallmouth we were targeting were eating threadfin shad in the 2-3" range.
The fish would be scattered in very large areas in the 50-150' range, I don't think depth was a concern to them. You could see the smallmouth chasing the shad on the surface. Typically it would be one fish (sometimes 2-3, but very seldomly), that would surface, blow up 2-4 times, and vanish. They were chasing individual shad, sometimes in groups of 10-15 (the shad), but once they got one, they went back down. Occasionally you could get one to eat a walking bait if you could get it to the fish in time, which typically didn't happen because of how spread out they were. We could see the fish on the graph suspended in the 20-35 foot range, and there were LOTS of them. We tried dropping drop shots to them, and the fish showed interest, but wouldn't bite the baits, they would just look at them for a while. I fished a deep diving crankbait that I know got in front of them, but to no avail. I fished a spybait, and I ended up catching one fish on that, but that was all. Tried a swimbait on a jighead, nada. Jerkbait (both deep and normal depth) nada. We tried several areas of the lake, and it was pretty much all the same.
Normally I would chalk this up to the fish being too keyed in on specific forage meaning they were basically uncatchable, but the problem was, we caught several 18-20" smallmouth while trying to target the brown and rainbow trout in the lake. They were hitting kastmaster spoons trolled behind 1 and 2 ounce weights.
Any advice or at least some sympathy? I really don't like it when I find the fish but can't catch them, and this was most definitely the case here!
