I would suggest you contact Paul Rister at KDFW...unless he has retired he is the fisheries biologist here in western Kentucky. He is the person I spoke with about this issue back when the money folks wanted the lake levels to be changed when the TVA was changing the River Operating System. He was very active in this issue along with his collegues. I think I will believe folks that make their living studying these things rather than anyone else that just has an opinion or has another agenda. There were a number of meetings held by the TVA back then about this issue...and the money folks were very vocal...luckily the KDFW and the TFWR were more vocal along with fishing advocates.
