Topo map advice

Can anyone help with where to order online or find a decent lake topo map? I know the Atlantic Mapping Company makes the best but those are TVA site maps...very accurate and good detail and have learned to really pay them attention previous to a trip or learning a lake. I live in Lex and fish some others (Barren, Cumberland mostly) and use my Navionics right now but really want to find some more detail on river channels, feeder creeks, etc.
Been online with not much luck. Hotspots maps are everywhere but are NOT accurate.
Advice by anyone who knows? Thanks as always

I would try emailing KY Fish and Wildlife info center and ask them. I think the have maps available for some lakes. I use my Navionics card but I think Navionics has a disk you can purchase with good detail maps, hope this helps you

Thanks. I'll call tomorrow.....
Appreciate the help.
