What to tie on at Preston Valley Access
Picked from recent reports for this stretch.
October Caddis
Recent intelligence signals from early fall (September 5th) indicate aggressive trout taking October Caddis. This hatch is seasonally active in early October on many freestone rivers.
Blood Dot Egg
Fall is prime egg season for trout below spawning fish, and this pattern effectively imitates salmon/trout eggs, which are a crucial food source for opportunistic feeders.

As water temperatures cool in the fall, larger trout become more aggressive, actively chasing streamers that imitate leeches and baitfish in deeper pools and runs.
Blue-Winged Olive Comparadun
Blue-Winged Olives are a consistent fall hatch on many freestone rivers, especially on overcast days. This low-profile dry fly is excellent for selective trout feeding on emergers and adults.
Pat's Rubber Legs
Larger stonefly nymphs are a year-round food source for trout. This weighted pattern is excellent for getting down to deeper holding fish in fall flows and acting as a lead fly in a nymph rig.

Small leech patterns, especially in olive, effectively mimic sluggish baitfish and annelids in cooling fall waters, enticing strikes from larger, lethargic trout.
Midge
Midges are a primary and consistent food source year-round in tailwaters and spring-fed sections like the Black Canyon of the Bear River, making them effective in fall.
Flashback Hare's Ear Nymph
A classic and versatile searching nymph, the Flashback Hare's Ear effectively mimics various aquatic insects and scuds active in fall currents.
Purple Haze
Recent early fall intelligence signals (September 5th) indicated this attractor pattern was effective for aggressive trout, suggesting it may still draw interest in early October.
