All KY lakes are on the navionics chip "East" Navionics just released a new 07 version of all their chips with all the lakes from last years version but with some lakes now in HD with 1' contours. In KY I think there are 4 lakes with 1' contours The twins, barren and DH, I think. It retails for 149.99, money well spent. You're going to have a hard time reformatting from garmin to lowrance, just pick up a nav. chip.
