Scud (Pink/Orange)
Freshwater amphipods (scuds) are a year-round staple in the Mackinaw River, mimicking an abundant food source for bluegill and carp, particularly around aquatic vegetation.
Buy at AmazonPheasant Tail Nymph
A year-round general mayfly nymph imitation, the Pheasant Tail Nymph is effective for bluegill, carp, and smallmouth bass, especially during the consistent nymph activity of fall.
Buy at AmazonSan Juan Worm
Aquatic worms are a consistent food source for carp and bluegill, especially after any rain events or flow fluctuations that might wash them into the Mackinaw River.
Buy at AmazonCrayfish (Fly)
Crayfish are a primary food source for smallmouth bass and carp in rocky river sections. Strip this pattern slowly along the bottom to mimic a fleeing crayfish, which is particularly effective in fall.
Buy at AmazonHellgrammite
Hellgrammites are a consistent, protein-rich food source for smallmouth bass year-round in rocky rivers, making this a reliable subsurface pattern as temperatures cool.
Woolly Bugger (Olive)
A versatile and essential streamer pattern that imitates leeches and baitfish, which are consistent food sources for predatory smallmouth, bluegill, and carp year-round, including fall.
Popping Bug (Bass)
On warmer fall afternoons, topwater action for bluegill and smallmouth bass can still occur. This popper creates an enticing surface disturbance, drawing aggressive strikes.
