About the tuolumne river
The Tuolumne River is a 149-mile-long river that starts in the Sierra Nevada mountains of California and flows through the Central Valley before emptying into the San Joaquin River. The river has a rich history, having been home to indigenous communities for thousands of years and later serving as a vital transportation route during the California Gold Rush. Today, the river is used for agricultural irrigation and hydropower generation. It is also home to several reservoirs and dams, including the Don Pedro Dam, the New Don Pedro Reservoir, and the Hetch Hetchy Reservoir. These provide drinking water to the San Francisco Bay Area and irrigation water to the Central Valley. The Tuolumne River is also popular for recreational activities such as fishing, camping, hiking, and whitewater rafting.
