Trout are actively feeding on eggs below spawning areas
- 01Trout are actively feeding on eggs below spawning areas, making egg patterns highly effective.
- 02Smallmouth bass are aggressively targeting crayfish and baitfish in cooler water, responding well to streamers and crayfish imitations.
- 03Fall mayfly hatches, particularly Blue-Winged Olives and Isonychia, provide sporadic dry fly action, especially on warmer, overcast days.
- 04Streamer fishing for both trout and bass can be highly productive as fish become more predatory.
- 05Midge activity remains a consistent food source subsurface, appealing to finicky trout.
What to tie on at Gilsum / Bridge Street
Picked from recent reports for this stretch.
Crayfish (Fly) (Olive/Rust)
Crayfish are a primary food source for smallmouth bass in rocky river environments, and this pattern is crucial in the fall as bass feed heavily.
Articulated Drunk Sculpin
Sculpin patterns are excellent for fall and winter bass, imitating larger baitfish that predatory bass key on in cooling waters.
Zebra Midge
Midges are the primary active forage in February; black or red versions are staple winter producers for both trout and panfish.

Blue-Winged Olives are beginning to hatch in early spring, especially on overcast days, making this a good choice for selective trout.
Scud (Pink/Orange)
Freshwater shrimp (scuds) are a consistent food source, and a pink or orange Scud can be very effective in early spring.
Buy at AmazonFlashback Hare's Ear Nymph
An excellent general searching nymph for early spring, mimicking various active mayfly nymphs.
Soft Hackle Wet (Partridge & Orange)
Caddis hatches occur spring through fall, and this pattern imitates caddis pupae and emergers.

Buy at AmazonHendrickson Nymph
Hendricksons are a key early spring hatch, with nymphs active subsurface and a primary food source for trout.
