Picked from reports, hatches and the season. Tap a fly for the recipe and where else it works.
October Caddis
The regional intelligence indicates October Caddis are becoming a significant factor, and fall is when the largest caddis hatch of the year occurs on many western rivers. This is a prime dry fly opportunity.
Mahogany Dun
Regional intelligence suggests Mahogany Dun patterns are starting to appear. Fall is a key time for Paraleptophlebia hatches, providing dry fly opportunities.

As fall BWO hatches begin, emerger patterns become crucial for fish feeding in the film. The hi-vis post helps detect subtle takes on these small insects.
Juan's Slim Shady
Blue-Winged Olive (BWO) patterns are beginning to appear according to regional intelligence, and this low-profile dry fly is excellent for selective trout keying on adult BWOs during fall hatches.
Chernobyl Ant Greys
This larger terrestrial pattern was explicitly mentioned in recent intelligence signals as effective in early fall, making it a good attractor for opportunistic feeders.
Woolly Bugger
An indispensable and versatile streamer, the olive Woolly Bugger imitates leeches and baitfish, which are consistent food sources for aggressive trout in cooling fall waters.
Hopper
Despite it being early October, regional intelligence confirms terrestrial fishing remains strong and active. With clear and 55F weather, hoppers can still be a substantial food source, especially along grassy banks.
Flashback Hare's Ear Nymph
This is an excellent general searching nymph, mimicking various aquatic insects and small mayfly nymphs that remain active in the currents throughout the fall.
Zebra Midge
Midges are a primary and consistent food source year-round, becoming even more important as other hatches wane in colder fall temperatures. This weighted pattern is effective for subsurface feeding.
