I have zero experience on KY/Barkley but I don't see why my past experience would not apply to those lakes...If the water gets into the treeline/bushes and it has very heavy color then yes the bass will get very shallow and very tight to the cover. If the color of the water allows light to penetrate a couple feet then they do not get as shallow or as close to the cover...now with that being said there is another factor in the equation and that is water temperature. What I described was for water temperatures like we currently have now. If the temperature gets into the upper 50's or low 60 then they get on the cover even if the water is not that dirty.
