    Comment: Runnable at these flows. Any higher, the crux of the canyon - rappelling directly under the flow of the 70-foot waterfall - could be quite difficult or even danergous! Would not recommend doing the canyon in higher flows than shown here unless you've done it before and know what you're committing to.
    Waterflow: Moderate-High
    Very Low Low Moderate-Low Moderate Moderate-High High Very High Extreme
    0% - 40% 40% - 70% 70% - 90% 90% - 110% 110% - 130% 130% - 160% 160% - 200% >200%

    • Very Low: Water flow should not represent any danger (class B = a2).
    • Low: Not as fun, but should be safe even for beginners (class B/C = a3).
    • Moderate-Low: A bit low, still fun but not very challenging (class C1- = a4-).
    • Moderate: Challenging but not dangerous for intermediate canyoneers (class C1 = a4).
    • Moderate-High: A bit high, quite challenging but not too dangerous (class C1+ = a4+).
    • High: High water, only for experienced swift water canyoneers (class C2 = a5).
    • Very High: Dangerously high water, only for expert swift water canyoneers (class C3 = a6).
    • Extreme: Extremely dangerous high water, may be unsafe even for experts (class C4 = a7).
