Picked from reports, hatches and the season. Tap a fly for the recipe and where else it works.
Hellgrammite Fly
Hellgrammites are a consistent food source on rocky rivers year-round. This subsurface pattern can attract Walleye foraging on the bottom.
Clouser Minnow
A universal baitfish imitation that is effective year-round for predatory species like Walleye. Its weighted eyes help it get down to cruising fish in deeper runs.
Conehead Sculpin
Sculpins are a common forage fish for Walleye near rocky bottoms. This pattern is best in fall when Walleye are actively hunting larger prey.
Buy at AmazonPerch Pattern
Walleye frequently prey on yellow perch. This imitation is prime for fall in lakes and rivers where perch are present.
Crayfish (Fly) (Olive/Rust)
Crayfish are a primary food source for Walleye in rocky river environments, making this a crucial subsurface pattern in fall.
Egg Sucking Leech
This pattern is effective year-round, especially in fall, for opportunistic Walleye that may key in on eggs or leeches.
Buy at AmazonPine Squirrel Leech
Small leech patterns effectively mimic sluggish baitfish and annelids in cold water, triggering strikes from larger, lethargic Walleye in the fall.
Buy at AmazonWoolly Bugger (Olive)
A highly versatile streamer imitating leeches and baitfish, which are consistent food sources for predatory Walleye, especially effective in fall conditions.
Articulated Streamer (Drunk Sculpin)
This sculpin imitation is excellent for fall and winter, mimicking larger baitfish that aggressive Walleye target in cooling waters.
