I like others have fished both lakes, from my own personal experience I would say Kentucky Lake seems the worse with a wind out of the South or North. I have been on Kentucky Lake in a heavy 19ft Ranger Reata and it would beat the heck out of you, no way would I ever do this in a 16 foot boat. Of course, we cannot predict the weather for March, but I would be flexible as possible even if it means trailing to another ramp which will provide the needed wind protection. As previously stated be careful on these lakes as winter pool will do you in if you are not familiar or go outside the channel markers or some ramps lack of water. I live in the Little River area of Barkley so it is fairly easy to find a wind protected area to fish, however a complete different story once you get out in that Main Chanel.
