Good action on dry flies here, especially prior to the approaching cold fronts or the “calm before the storm”. Cast 10-15′ above your targeted fish to get your presentation on the water well upstream of them. I like 10-12′ leaders here to avoid spooking the surface feeders with your fly line splashdown. Elk Caddis, Parachute Adams, and midge patterns in #18-22 are best. You can attach a short dropper nymph about 2′ or so to your dry when the fish aren’t feeding on top. Good patterns are #18-20 copper tiger and zebra midges and #20 PT’s with or without flashbacks.
