Fall often brings intermittent Blue-Winged Olive (BWO) hatches, particularly on overcast days. This low-profile dry fly is excellent for selective Steelhead, Loopers, and Walleye feeding on emergers and adults.
Flashback Pheasant Tail Nymph
An excellent general searching nymph, mimicking various active aquatic insects, which remain a food source for Walleye, Steelhead, and Loopers in fall currents.
Woolly Bugger (Olive)
A highly versatile streamer, the olive Woolly Bugger effectively imitates leeches and baitfish, which are consistent food sources for predatory Walleye and Steelhead in cooling fall waters.
Comet
The Comet is explicitly recommended for fall steelhead, and can also attract opportunistic Walleye.

Small leech patterns like this effectively mimic sluggish baitfish and annelids in cold water, enticing strikes from larger, lethargic Walleye, Steelhead, and Loopers.
Egg Sucking Leech
This combination pattern imitates both a leech and an egg, a highly effective presentation during fall when eggs are present in the water and predatory fish like Walleye, Steelhead, and Loopers are looking for larger meals.
