    What's working on Trappers Lake

    Tactical tipGo Slow and Stealthy: In the typically clear and calm water of Trappers Lake during fall, presentation is paramount. Employ longer leaders (9-12 feet) with fine tippets (5x or 6x) for nymphs and dry flies to avoid spooking wary fish. When fishing nymphs and leeches, a slow, deliberate retrieve with intermittent pauses often triggers strikes from lethargic fish. When targeting rising fish during BWO hatches, a precise, unweighted presentation is key.
    1. 01Stable Fall Conditions: Anglers visiting Trappers Lake this week can anticipate pleasant fishing conditions with clear skies, temperatures around 45°F, and a light southwest wind (9 mph). These conditions are perfect for a quiet day of stillwater angling.
    2. 02Blue-Winged Olive (BWO) Hatches: Keep a keen eye out for Blue-Winged Olive (BWO) hatches, which are still actively occurring. These smaller mayflies typically emerge during the warmer, often overcast, afternoons. Observe the surface carefully for subtle rises, especially in sheltered bays or along current seams if any micro-currents are present near inlets/outlets.
    3. 03Consistent Midge Activity: Midges remain a foundational food source in Trappers Lake. Expect consistent subsurface midge activity throughout the entire day. Trout will be steadily feeding on midge pupae and larvae in the water column and near the bottom, making nymphing tactics with small imitations absolutely essential.
    4. 04Aggressive Streamer Bite: As water temperatures continue their steady decline, the lake's trout, particularly the larger cutthroat and rainbows, are becoming increasingly aggressive. They are actively seeking out bigger, calorie-rich prey to fuel their pre-winter feeding frenzy. This makes stripping streamers, mimicking baitfish or leeches, a highly effective tactic to entice trophy-sized fish.
    5. 05Prime Locations: Drop-offs and Weed Lines: Focus your efforts strategically along Trappers Lake's distinct drop-offs, submerged weed beds, and the transition zones where these features meet deeper water. These areas serve as prime ambush points for cutthroat trout, where they will be actively intercepting emerging insects and foraging for larger food sources before the lake freezes over.

    What to tie on

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

    nymph

    Albino Midge

    #20#22#24

    Given Trappers Lake is a stillwater, this midge pattern is highly effective during significant midge hatches for cutthroat trout keying in on this abundant food source.

    dry

    Blue-Winged Olive (BWO) Comparadun

    Baetis (BWO) adult
    #18#20#22#24

    Matches the expected fall BWO hatches, which are common in high-altitude lakes, targeting selective rising cutthroat trout.

    streamer

    Balanced Leech (Black)

    #14#16

    Leeches are a major food source in stillwaters, and a balanced leech fished under an indicator is highly effective for larger cutthroat trout in the colder fall waters.

    nymph

    Baetis Nymph

    Baetis (BWO) Nymph
    #16#18#20#22

    Baetis nymphs are active year-round and particularly in the fall, offering a consistent subsurface food source for trout. Fish this dead-drift or with a slow retrieve.

    nymph

    Zebra Midge

    Midge pupa (Chironomidae)
    #18#20#22#24

    Midges are a primary and consistent food source in stillwaters, especially in fall as temperatures drop. This weighted nymph gets into the strike zone for subsurface feeders.

    emerger

    Travis Hi-Vis BWO Para Emerger

    #18#20#22

    BWO emergers are crucial during fall hatches as water temperatures cool. The high-visibility parachute helps detect subtle takes from feeding trout.

    nymph

    Mysis Shrimp (Nymph)

    #14#16#18

    As a large lake, Trappers likely holds Mysis shrimp, a significant food source for trout. Fish this dead drift near the bottom to target subsurface feeders.

    dry

    October Caddis (Dry)

    October Caddis (Dicosmoecus) adult
    #6#8#10

    October Caddis are the largest caddis hatch of the fall. A large dry fly imitation can draw aggressive strikes from opportunistic cutthroat trout, especially near the shore.
