I live 5 minutes from the middle section of the lake. I can tell you that today it was dingy to off colored in the channel at DA Green Bridge. The major feeder creeks were pouring in muddy water yesterday but clearing a little by this afternoon. According to TVA website it has come up about 3ft, and will probably raise another foot before leveling off and they pull it back down some. By tomorrow afternoon I expect the upper half of the lake will be stained considerably if not muddy. The lower half should not be affected as much. If you are fishing a particular area I might be able to check it out from the boat ramps if I have time. Good luck if you come down.
PS Having 15mph winds tonight so it probably will not help matters.
