    What's working on Lightning Creek

    1. 01Clear skies and moderate 54°F temperatures create fair fall fishing conditions on Lightning Creek.
    2. 02Expect active Blue-Winged Olive (BWO) and Pale Morning Dun (PMD) hatches, particularly during the warmest parts of clear afternoons.
    3. 03The substantial October Caddis hatch is also a strong possibility for surface activity.
    4. 04Trout may be keying into egg patterns due to potential local salmonid spawning activity.
    5. 05Focus on deeper pools, current seams, and slower runs with cover for holding fish and rising trout.
