Picked from reports, hatches and the season. Tap a fly for the recipe and where else it works.
Jujubaetis
As water temperatures drop in fall on the Greybull River, Baetis nymphs remain a primary food source. This pattern effectively imitates the active subsurface nymphs.
Buy at AmazonOlive Woolly Bugger
Fall is prime streamer season on the Greybull River. An olive Woolly Bugger effectively imitates leeches and baitfish, which are consistent food sources for aggressive trout in colder water.
Blue-Winged Olive (BWO) Comparadun
Blue-Winged Olives are actively hatching in early fall on the Greybull River, providing excellent technical dry fly opportunities, especially on overcast days. This low-profile dry fly is excellent for selective trout feeding on emergers and adults.
Buy at AmazonZebra Midge
Midges are a consistent, year-round food source on the Greybull River, and become especially important as other hatches wane in colder fall water. This nymph is effective for enticing finicky trout subsurface.
Buy at AmazonHarvey Pusher
For targeting larger, aggressive Brown Trout in the fall on the Greybull River, the Harvey Pusher is an excellent baitfish and sculpin imitation, best stripped through deep runs.
Travis Hi-Vis BWO Para Emerger
BWO emergers are crucial during fall hatches on the Greybull River as trout key in on vulnerable insects in the surface film. This high-visibility pattern helps spot subtle takes.
Schroeder’s Parachute Hopper
While late in the season, terrestrial activity can still be strong in early fall along the Greybull River's grassy banks, making a hopper pattern a good attractor for opportunistic trout.
