International scale of river difficulty information
Scale of skill needed to navigate a section of river
Class III rapid at Canolfan Tryweryn, Wales.
The international scale of river difficulty is an American system used to rate the difficulty of navigating a stretch of river, or a single (sometimes whitewater) rapid.[1] The scale was created by the American Whitewater Association to evaluate rivers throughout the world, hence international in the title.[2]
It should not be confused with the internationally used whitewater scale, which is published and adapted by a committee of the International Canoe Federation (ICF).[3][4]
The grade reflects the technical difficulty and skill level required associated with the section of river. The scale is of use to various water sports and activities, such as rafting, riverboarding, whitewater canoeing, stand up paddle surfing, and whitewater kayaking.[5]
