I'm going out to wade the upper yak for the first time on Sunday. I've been to the canyon a bunch of times and have had some relative success with throwing dries near the bank during the hatches and hitting the oxygenated water during the day with nymphs and streamers. Not rocket science. The natural environment is so different between the upper yak and canyon, do you all change your tactics drastically between the two parts of the river-- with bugs or presentation? I'll obviously swing by the fly shop in Cle Elum beforehand, but just wanted to hear if people had any thoughts.
