List of Grand Canyon rapids and features information
The following is a list of major rapids and other notable features on the Colorado River through Marble Canyon and Grand Canyon below Glen Canyon Dam, in order of their position downstream of Lee's Ferry. Ratings are given for how difficult the rapid is to navigate by whitewater raft or other water craft. The Grand Canyon section of the Colorado River, like several other big-water Western rivers, uses a rapids scale developed by Otis R. Marston of 1–10 for rapids, 10 being the most difficult. The International Scale of River Difficulty, which classifies rapids from class I to VI, is more common elsewhere in the US and internationally.

Mile 280.5 – Pearce Ferry Take-out at Pearce Ferry, Lake Mead, is the first take-out point for river trips traveling through the entire Grand Canyon. This Take-Out (on Lake Mead) has been recently renovated, making it operational at low reservoir levels. With the appearance of Pearce Ferry Rapid, this take-out has become preferred, as the rapid just below is often considered unrunnable, though this is always changing.
Mile 280.8 – Pearce Ferry Rapid (unrunnable; class VI on the International Scale of River Difficulty) This rapid was created in 2007 when the level of Lake Mead went below 1138 feet. Lake Mead was over 70 feet deep here in 2000. This rapid is formed by the Colorado River running full force into a hillside. It is a must-scout for any river runners continuing to the next take-out on Lake Mead at South Cove. It is currently considered to be unrunnable.[6]
Mile 297 – South Cove Take-Out (in Lake Mead)
