    What to tie on

    Picked from reports, hatches and the season. Tap a fly for the recipe and where else it works.

    nymph

    Hellgrammite Fly

    Hellgrammite (Dobsonfly larva)
    #4#6#8

    Hellgrammites are a consistent, protein-rich food source year-round on rocky rivers. This pattern offers a substantial subsurface meal for Smallmouth Bass, Walleye, Carp, Sauger, Bluegill, Muskellunge, Catfish, Crappie, Panfish, and Sunfish in the fall.

    streamer

    Woolly Bugger (Black)

    #4#6#8

    A black streamer effectively imitates leeches and sculpins, which remain active even in cooler water. This is a high-searching pattern for larger predatory fish in the Mississinewa River, including Walleye, Crappie, Bluegill, Sunfish, Muskellunge, Catfish, Carp, Wipers, Perch, and Sauger.

    dry

    Crayfish (Fly) (Olive/Rust)

    #14#16

    Crayfish are a primary food source for many species including Smallmouth Bass, Largemouth Bass, Walleye, Channel Catfish, Bluegill, Black Crappie, and Carp in rocky river environments. This pattern is crucial for subsurface feeding in the fall.

    streamer

    Muskie Fly

    Baitfish
    #3/0#4/0#5/0

    Specifically designed for Muskellunge, this large streamer is highly effective in the fall when these apex predators are actively feeding in preparation for winter.

    streamer

    Woolly Bugger (Olive)

    #4#6#8

    A versatile streamer, effective for imitating leeches and baitfish, which are consistent food sources for predatory species like Walleye, Crappie, Bluegill, Sunfish, Muskellunge, Catfish, Carp, Wipers, Perch, and Sauger as water temperatures cool in the fall.

    streamer

    Clouser Minnow (Bass) (Chartreuse/White)

    #4#6#8

    This baitfish imitation is a go-to for predatory species like Walleye, Crappie, Bluegill, Sunfish, Muskellunge, Catfish, Carp, Wipers, Perch, and Sauger, especially when baitfish are present and active, even in cooling fall waters.

    streamer

    Perch Pattern

    Yellow Perch
    #1/0#2#4

    Fall is prime time for predatory species such as Walleye, Muskellunge, Pike, Sauger, Wipers, Crappie, and Perch to feed on abundant yellow perch fry and juveniles, making this a highly effective imitation.

    dry

    October Caddis (Dry)

    October Caddis (Dicosmoecus) adult
    #6#8#10

    While terrestrial activity wanes, October Caddis can provide significant surface action in the fall for species like Crappie, Walleye, Perch, Sunfish, Bluegill, Panfish, Carp, and Bass on warmer days.
