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.

“The Humanity of men and women is inversely proportional to their Numbers. A Crowd is no more human than an Avalanche or a Whirlwind. A rabble of men and women stands lower in the scale of moral and intellectual being than a herd of Swine or of Jackals.”
—Aldous Huxley (1894–1963)
“I cannot tell how many times we had to walk on account of falls or rapids. We were expecting all the while that the river would take a final leap and get to smooth water, but there was no improvement this forenoon.”
—Henry David Thoreau (1817–1862)
“Because they did not see merit where they should have seen it, people, to express their regret, will go and leave a lot of money to the very people who will be the first to throw stones at the next person who has anything to say and finds a difficulty in getting a hearing.”
—Samuel Butler (1835–1902)
