Bite report · week of Oct 4

Clear

01Clear, moderate water conditions, ideal for both dry fly and subsurface fishing.
02Active hatches of Pale Morning Duns (PMDs) in sizes 16-18, offering good dry fly action.
03Strong terrestrial activity with hoppers (sizes 8-12) along grassy banks.
04October Caddis (sizes 6-10) are emerging, providing significant surface feeding opportunities.
05Consistent subsurface nymphing with midges and mayfly patterns remains effective.
06Focus efforts from Hyrum to Hardware Ranch, targeting deeper runs and current seams.
07Use longer leaders and drag-free drifts for dries; ensure weighted nymphs reach the bottom for Whitefish.

What to tie on at Hyrum State Park Bridge

Picked from recent reports for this stretch.

egg95%

Blood Dot Egg

#10#12#14

As trout begin their fall spawning cycle, egg patterns become highly effective, and Whitefish will readily feed on loose eggs in the drift.

Hopper

#6#8#10

Terrestrial hoppers remain an important food source in early fall, especially along grassy banks where Whitefish will opportunistically feed on the surface.

dry90%

October Caddis (Dry)

#6#8#10

The October Caddis hatch is a significant fall event on western rivers, providing a large meal that Whitefish will actively pursue on the surface.

dry90%

PMD Comparadun (BWO)

#18#20#22

PMD hatches are active in October on the Blacksmith Fork River, and Whitefish are opportunistic feeders. This low-profile dry fly is excellent for selective fish feeding on emergers and adults.

nymph85%

Zebra Midge (Black)

#20#22#24

Midges are a consistent food source year-round on the Blacksmith Fork, and this weighted nymph is excellent for targeting subsurface feeding Whitefish in cooler fall temperatures.
