Back to Rafting Class I. | Easy | Waves small, passages clear; no serious obstacles | Class II | Medium | Rapids of moderate difficulty with passages clear. | Class III | Difficult | Waves numerous, high, irregular; rocks; eddies; rapids with passages clear though narrow, requiring expertise in maneuvering. | Class IV | Very Difficult | Long rapids; waves powerful, irregular; dangerous rocks; boiling eddies; powerful and precise maneuvering required. | Class V | Extremely Difficult | Exceedingly difficult, long and violent rapids, following each other almost without interruption; riverbed extremely obstructed; big drops; violent currents; very steep gradient. | Class VI | Unrunnable | Don't even try - if you fall in (hopefully with a life preserver and helmet) float down feet first to avoid the rocks hitting your tail bone and try to get to the side to crawl out. | P | Portage | Boats must be carried along the river bank to get around an unrunnable stretch of river. |
Flow rates or CFS (cubic feet per second) is another indication of the condition of the river.
So it's good idea to have this information too when planning a rafting trip.
A river that has10,000 CFS is going to be a wild ride.
