LBL Cross Creek, Paris Landing area, New Johnsonville, Cumberland City Steam Plant... I have caught fish at all these places, when I lived in Clarksville / Ft Campbell. New Johnsonville is a pretty good jog from Clarksville, but make a weekend of it, and go camping. use to be a lot of good shore fishing.
Paris Landing is pretty good, but need a boat to hit a bunch of good spots.
Lots of good little fishing holes around LBL... You have to hit Cumberland City at the right times.. Suggest you go check it out. Talk to locals there..
There used to be a Bait Store on HWY 70 around the Bumpus Mills area, about 4-5 miles before you hit the Dover Bridge... Not sure if it is still there, but they always had to daily / weekly fishing report..
It been a few years since I have fished these area (17 to be exact), but always had fun and caught fish.
