This is a string describing the water flow in the canyon based on an absolute scale of risk and potential consequences. The allowed values for this property are:
0 - Dry (class A = a1) : Completely dry or all pools avoidable
1 - Very Low (class B = a2) : No current or just a trickle, may require shallow wading
2 - Deep pools (class B+ = a2+) : No current or just a trickle, may require swimming
3 - Low (class B/C = a3) : Light current, more than just a trickle but still weak
4 - Moderate Low (class C1- = a4-) : A bit low, still fun but not very challenging
5 - Moderate (class C1 = a4) : Moderate current, challenging but easy water hazards
6 - Moderate High (class C1+ = a4+) : A bit high, quite challenging but not too dangerous
7 - High (class C2 = a5) : High water, only for experienced swift water canyoneers
8 - Very High (class C3 = a6) : Dangerously high water, only for expert swift water canyoneers
9 - Extreme (class C4 = a7) : Extremely dangerous high water, may be unsafe even for experts
For more information on water ratings see the ACA Water ratings or French Aquatic rating pages.

C0 - Very Low flow : Water flow should not represent any danger
C½ - Low flow : Not as fun, but should be safe even for beginners
C1 - Moderate Low flow : A bit low, still fun but not very challenging
C1 - Moderate flow : Challenging but not dangerous for intermediate canyoneers
C1 - Moderate High flow : A bit high, quite challenging but not too dangerous
C2 - High flow : High water, only for experienced swift water canyoneers
C3 - Very High flow : Dangerously high water, only for expert swift water canyoneers
C4 - Extreme flow : Extremely dangerous high water, may be unsafe even for experts
