Bassky ... the only one I know of is Cedar Creek Lake. Supposedly (according to the report from Cedar Creek Lake Outfitters 5/17/11) the gills & crackers were bedding, and quality fish were being caught (back then). I'm hoping to get a chance to try it around the next full moon, myself.
If it wasn't so small, and crowded (fish & anglers), and the Shad hadn't survived the eradication efforts of the KDFWR ... Cedar Creek could have been a rival of KY/Barkley lakes, for big gills & crackers. The Crappie would probably have done better, too.
I've caught several "good sized" crackers ... and I've seen pics of a couple of 2lb+ crackers ... but you have to wade thru a ton of little ones, before you'd have a chance at anything >6" long.
Some people seem to be able to catch some good sized gills out of Taylorsville Lake ... but, I've only heard about them, never actually done it myself.
Have you fished those two lakes off of I75 (between Alexandria & Lexington) ... around Dry Ridge & Falmouth ??? (Williamstown Lake & Kincaid Lake)
Cedar Creek is a hour drive south of LEX ... so it would be ~ 2.5hr drive for you +/- .... and I'd hate to recommend the lake, and have you not have a productive trip.
