    What's working on Stillwater River

    1. 01Blue-Winged Olive (BWO) hatch is the primary focus for October, with strong emergences expected.
    2. 02Larger October Caddis are becoming a significant food source, triggering aggressive surface takes.
    3. 03Stillwater River is flowing at 383 cfs, offering nuanced fall fishing opportunities.
    4. 04Key dry flies include Parachute BWO, Blue-Winged Olive Comparadun, and October Caddis (Dry).
    5. 05Effective subsurface patterns include Jujubaetis for nymphs and Woolly Bugger (Olive) for streamers.
    6. 06Focus fishing efforts downstream of Nye to the Yellowstone River confluence for strong BWO activity.
    7. 07Target slower current seams, eddy lines, and soft water behind rocks.
    8. 08Precise, drag-free drifts are crucial for dry fly success, especially with selective BWO feeders.
    9. 09Consider dry-dropper rigs with BWO nymphs for varied water columns.
