The thrill of the rapids. The serenity of calm waters. The Tuolumne River gave you an experience you'll never forget. But this magnificent waterway faces threats from pollution, development, wildfires, and climate change.

Tuolumne River Trust has been the dedicated guardian of this natural treasure since 1981. We work tirelessly to protect water quality, restore wildlife habitat, and ensure future generations can experience the same magic you felt today.
