How to Understand River Rapid Rating Systems

Learn to properly read the white-water rapid rating system to gauge the difficulty level of the river before embarking upon a rafting trip.

Difficulty: Easy

Instructions

Things You'll Need:

• River Raft First Aid Kits
• Life Vests
• Nautical Ropes
• River Raft Oars
• River Raft Paddles
• River Raft Repair Kits
• River Rafts

1. Realize that there are two different rating systems: the European scale (International Scale of River Difficulty) and the American scale.

2. Read the European scale from I to VI, with I being the easiest and VI being unnegotiable.

3. Read the American scale from 1 to 10, with 1 being the easiest and 10 being very dangerous.

4. Understand that different water levels can affect the rating of a rapid one way or the other. Some rapids are more dangerous in low waters, and some are more dangerous in deeper waters.

5. Know the rating for each rapid you'll encounter on your rafting trip before you embark. Know the rating for that particular time of year, for that particular year.

Tips & Warnings

• Make sure the rating system you use for a river is current. Check the dates and ask the rangers.
• Always plan and prepare well before a rafting trip. Make sure your raft is outfitted for all types of emergencies. Include extra ropes, a raft repair kit, a first aid kit, and life vests.
• River rafting is an inherently dangerous activity that can result in serious injury or death. We recommend that you seek proper training and equipment before attempting this activity.
