Muskie Fly
Fall is prime time for muskie in large lakes like Causey Reservoir, as they actively hunt baitfish to bulk up for winter.
Game Changer (Perch)
Large baitfish imitations like the Game Changer are excellent for targeting aggressive predatory fish, including Tiger Muskie and larger trout, as they feed on available perch and baitfish in Causey Reservoir during the fall.
Balanced Leech (Black)
Leeches are a staple forage for predatory fish in stillwaters year-round. This pattern is highly effective in Causey Reservoir, mimicking sluggish leeches that Cutthroat, Tiger Trout, and Tiger Muskie will readily prey upon in cooler fall waters.
Mysis Shrimp (Nymph)
As a large reservoir, Mysis shrimp are a consistent and important food source for trout. Fishing this pattern dead drift near the bottom of Causey Reservoir can be highly effective for subsurface feeding Cutthroat and Tiger Trout in the fall.
Red Zebra Midge
Midges, especially blood midge variations, are a primary food source in reservoirs as fall progresses towards winter. This red pattern can be a key trigger for Cutthroat and Tiger Trout in Causey Reservoir.
Glo Bug
Fall is prime egg season as various trout species begin to spawn. Glo Bugs are highly effective for Cutthroat and Tiger Trout keying into these protein-rich food sources in Causey Reservoir.

Large dragonfly nymphs are a substantial and consistent food source for cruising trout in lakes throughout fall. Stripping this pattern slowly along weed edges in Causey Reservoir can entice strikes from Cutthroat and Tiger Trout.
PMD (Pale Morning Duns)
While major hatches are waning, Pale Morning Duns can still hatch on warmer fall afternoons, providing opportunistic Cutthroat and Tiger Trout in Causey Reservoir a chance to feed on the surface.
