What to tie on at South Pekin Launch / Upper Mackinaw Put-in
Picked from recent reports for this stretch.
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 AmazonBeetle
Terrestrial beetles are often dislodged from streamside vegetation during summer, providing an easy meal for Bluegill and opportunistic Carp.
Damsel Nymph (Olive)
Damsel nymphs become highly active in late spring and summer, making this pattern ideal for stripping slowly along weed beds where Bluegill and Carp forage.
Crayfish (Fly)
Crayfish are a primary food source for larger Carp in rocky areas. This pattern is effective when stripped slowly along the bottom.
Buy at AmazonScud (Pink/Orange)
Freshwater shrimp are a consistent food source in freshwater systems, and a pink/orange variant is effective in early spring for Bluegill and Carp.
Buy at AmazonWoolly Bugger (Black)
A versatile streamer effective year-round for predatory warmwater fish like Bluegill, Carp, and Smallmouth Bass, imitating leeches and baitfish in warming spring waters.
Crappie Jig Fly
Mimics small baitfish and invertebrates, which Bluegill and Carp feed on, and is effective around structure during spring activity.
Buy at AmazonDamsel Nymph (Olive)
Damsel nymphs become active in late spring as they migrate towards shore to hatch, providing a crucial food source for Bluegill and Carp in vegetated areas.
San Juan Worm
Aquatic worms are easily washed into the river, especially with light drizzle, making this a highly effective pattern for Bluegill, Carp, and Smallmouth Bass.
