The lower river remains tough fishing. The exception is to try streamers at twilight. Terrestrials patterns are the name of the game during daytime on the upper river. So is the early morning trico emergence. Be stealthy–“Henry’s Fork Hunchback and all that” during these bright days. Cumulus build-up will help your chances for success and also bring out some speckled duns and late season PMDs. Evening caddis swarms can bring some action and fishing success then will pick up just about any time if you are grazed by a thundershower.
