The only lakes I know of North of Lex. that would be good for Crappie would be Taylorsville or Cave Run. Of those Taylorsville would probably be the best although I havn't fished either in some time. Your best Crappie lakes in KY would be Barkley and KY Lake although with the price of gas being what it is those trips would cost quite a bit more. Maybe someone else can chime in here. Best of luck! - Newlight
