    Flows are consistently clear and cold

    1. 01Flows are consistently clear and cold, largely unaffected by runoff, maintaining ideal trout habitat.
    2. 02Trout are becoming more active and aggressive as water temperatures cool, moving into shallower feeding lanes.
    3. 03Key hatches expected include Tricos, Western Green Drakes, PMDs, and prolific Blue-Winged Olives, especially on overcast days.
    4. 04Good numbers of large October Caddis are anticipated, providing exciting late afternoon and evening dry fly action.
    5. 05Wading is not possible; boat access (pram or other watercraft without gas motors) is essential for covering water on Fall River.
