I tried like hell to pull some sandbass out of there this spawn, but I started in March and maybe was a little late. Still, I didn't catch anything. Haven't targeted cats though. I tried around Alton Bridge down to a couple miles, but this time of year you might have have better luck off some points off LL. I'm new to hickory creek though, so maybe I was doing something wrong. I heard when the utilities dammed up HC north of Old Alton it messed things up bc the fish can't get past. Maybe they started spawning more up towards 380.
If you're fishing Hickory for whites, you need to be going WAY upstream from Old Alton. You need to be looking for rocky and gravel bottoms, not the muddier part of the creek closer to the lake. There's nothing preventing fish from going way upstream.
