I have found that wading is difficult anytime flow is above 5 K, using a boat is difficult anytime the flow is below 2K. Watch the lake level. When the lake is 685 or above, flow will be 5k+; as the lake drops toward 680, flow will drop below 5K. At 680, the flow drops down to 500 cfs or so. Unfortunately, I've found this year and last that relatively high water temps--60 degrees and above--has given the trout lockjaw, and 60 degrees+ is pretty much what you get, no matter the flow, from May until November. Only high lake levels for extended periods of time will generate the really cold water we used to have during the summer. No telling when that will happen, as the dam will be under repair for the foreseeable future.
