choppy is a understatement. ky lake is a HUGE lake that actually has a horizon and if the wind gets blowing north/south you will have big swells. i've been there when there were 4ft swells and it was one of the scariest things i've ever been a part of. but there are tons of high spots on that lake, you can be in 30 foot of water and 5 foot to your left there will only be 4 foot of water. there are tons of ledges on that lake making it very dangerous if you leave the channel and don't have a clue where the shallow spots are. if you stay in between the channel markers you'll be fine. hopefully someone else will chime in and help because i'm not much help. i only go there once a year.
