    • 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).
