Rapids Ratings Information

Below are the rapids ratings used in this book. Remember, rivers are a force of nature and therefore constantly changing—what is easy water today might become hazardous as water levels fluctuate. Approach any whitewater with caution.  

Class I- Novices should have few problems with these rapids. Some fast water with small waves. Obstacles easily spotted and avoided.  

Class II- Moderate rapids with faster currents and multiple channels. There are also more rapids or longer stretches of rapids.   

Class III- Difficult rapids. Solid whitewater paddling skills necessary. Irregular waves, fast current and difficult to recognize course, as well as frequent obstructions.  

Class IV- Extremely difficult rapids requiring very strong paddling skills. Must have the ability to quickly maneuver around obstructions and hazards. Strong currents unavoidable.  

Class V- Extreme danger—for experts only. Large rocks, holes, waves and violent current.
