What to tie on at Upper Lolo Trail Access

Picked from recent reports for this stretch.

Matches the prominent October Caddis hatch now active on the river, a key fall food source.

BWOs are actively hatching in the fall, especially on overcast days, and a Comparadun is an excellent low-profile pattern for selective fish.

Fall hatches of Mahogany Duns are underway, providing excellent dry fly opportunities for trout keying on adult mayflies.

Terrestrials like hoppers are still a significant food source in early fall along grassy banks, attracting opportunistic feeders.

An excellent Baetis nymph for subsurface feeding, perfectly matching the active BWO nymphs when trout aren't rising to dries.

A versatile nymph that imitates various active aquatic insects, effective year-round, especially when fish are feeding subsurface.
