Flav’s (#14) and Fall Drakes (#10) are hatching along with Mahogany Duns (#16), PMD’s (#16) Baetis (#18-20).
Little Olive Stones are coming on with a vengeance this 4th day of September. Check out our new double wing stone and always have a few Hemingway’s or Henryville’s in a #18 on board. We find trimming the hackle flat on the bottom is usually what the fish like best.
Still quite a few stoneflies of the larger species out as well.
Caddis hatches are no slouch either. We love September hatches on the Metolius. Most of the fish we are getting are on these 3 patterns: Siddac #16, Iris Caddis #16-18 and the Missing Link #16-18.
Nymphing is fine but really with all these hatches in September I usually leave the nymph box behind.
Bull Trout fishing continues to be good (better than average) and you know the drill with the big white streamers on a 7 or 8 weight. I say what rod to fish because too many people show up to buy the flies and go “whoa, I can’t throw that with my 5 weight!” . No you can’t. You need a meat stick, so bring the power rod. Besides, some of these BT’s go 10 pounds or more.
