The International Scale of River Difficulty is a standardized scale used to rate the safety of a stretch of river, or a single (sometimes whitewater) rapid. 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, and whitewater kayaking.
