Wouldn't spend too much time on Walleye on Tionesta Ck above the Tionesta Dam. Unsuccessful in introducing them to the Dam a decade or so ago, which would be the source of any Walleye in 'upper' Tionesta Ck. The Walleye in the Outflow likely get re-populated from a combo of spawn/migration up from the Allegheny River, since the wood dam is no longer a barrier to fish from Allegheny, but get a lot of pressure at the Outflow wall(s).
Sad to hear that you saw dead stockies at Salmon Ck, it has been an unusually warm and dry summer, perhaps even Salmon Ck has temps in 60's/70's during daytime, stressing Trout. Fear not, the fall chill is coming, and the fish will turn on like clockwork.
Enjoy!
