Whitewater Workshop - Grand Canyon River Guide

This Whitewater Workshop page from Belknap’s Grand Canyon River Guide explains how Glen Canyon Dam’s fluctuating water releases impact river flow levels in the Grand Canyon. It discusses how peak energy demands affect downstream boating conditions and provides contacts for real-time flow data. The page also outlines how river trips are regulated under the Colorado River Management Plan (CRMP), including details about commercial outfitters, permit systems, and seasonal restrictions. It’s a practical resource for understanding river hydrology, permit logistics, and trip planning for both motorized and non-motorized rafting in Grand Canyon National Park.
