    Bite report · week of Oct 4

    Clear

    1. 01Clear, moderate water conditions, ideal for both dry fly and subsurface fishing.
    2. 02Active hatches of Pale Morning Duns (PMDs) in sizes 16-18, offering good dry fly action.
    3. 03Strong terrestrial activity with hoppers (sizes 8-12) along grassy banks.
    4. 04October Caddis (sizes 6-10) are emerging, providing significant surface feeding opportunities.
    5. 05Consistent subsurface nymphing with midges and mayfly patterns remains effective.
    6. 06Focus efforts from Hyrum to Hardware Ranch, targeting deeper runs and current seams.
    7. 07Use longer leaders and drag-free drifts for dries; ensure weighted nymphs reach the bottom for Whitefish.

    What to tie on

    Picked from reports, hatches and the season. Tap a fly for the recipe and where else it works.

    egg

    Blood Dot Egg

    Salmon/trout 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.

    terrestrial

    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.

    dry

    October Caddis (Dry)

    October Caddis (Dicosmoecus) adult
    #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.

    dry

    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.

    nymph

    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.

    nymph

    Hare's Ear Nymph

    Mayfly nymph (general)
    #12#14#16#18

    This versatile nymph imitates a variety of aquatic insects active year-round and is a reliable pattern for Whitefish feeding subsurface in the Blacksmith Fork.

    nymph

    Tungsten Bead Pat's Rubber Legs

    Stonefly nymph (Plecoptera)
    #4#6#8#10

    Large stonefly nymphs are present year-round and offer a substantial meal for Whitefish. This weighted pattern effectively reaches fish holding in deeper runs.

    streamer

    Woolly Bugger (Olive)

    #4#6#8

    Leeches and baitfish are consistent forage, and a slowly stripped Woolly Bugger in olive is an excellent searching pattern for opportunistic Whitefish in the cooler fall water.
