    Low, clear flows on the Big Wood require attention to temperature swings and careful presentation as fall hatches begin to show.

  • Covers Aug 19–26

    window closed

    The Big Wood is rising with improving water temperatures heading into late August. Look for a mix of dry action and nymph fishing on less-pressured stretches.

  • Covers Aug 12–19

    window closed

    The Big Wood is running low and clear through mid-August. Success depends on stealth and exploring less-fished water between access points.

  • Covers Aug 5–12

    window closed

    Low flows persist with clear, rising pressure and minimal precipitation expected. Fish the morning window aggressively; afternoon fishing will be slower as water warms.

  • Covers Jul 29–Aug 5

    window closed

    Low flows make for excellent wading on the Big Wood, with morning hatches followed by good afternoon opportunities using terrestrials and nymphs.

  • Covers Jun 10–17

    window closed

    The Big Wood is running at normal flow and stable. Braided sections and lower-gradient areas offer the best fishing in current conditions. Green Drake emergence is imminent, so nymph and dry patterns deserve attention.
