History
The Hetch Hetchy System had its birth in the Raker Act of 1913, which granted water and power resource rights-of-way on the Tuolumne River in Yosemite National Park to San Francisco. The total system is the realization of a concept for an aqueduct from the Sierra Nevada watersheds, which had been planned since the 1860’s.  A very busy 20 years of construction on the Hetch Hetchy dams and aqueducts resulted in Sierra Nevada water being delivered into the Water Department local distribution system by 1934.  Integrating Hetch Hetchy and Water Department systems has provided San Francisco and neighboring communities with an unfailing year-round assured supply of pure, potable water from secure sources.

The city’s need for reliable water supplies after the devastation of the Great Earthquake and Fire of 1906 brought the brightest engineers of their day to meet the challenges of hydraulic engineering across more than 160 miles of wilderness, developing new technologies and construction techniques, mastering impassable terrain and intractable financial woes to complete the incredible water works that fosters the high quality of life and economic strength that our 21st century San Francisco Bay Area enjoys.

Before building the essential elements of the system, it was first necessary to get into the mountains with packers and guides, often using chartered stagecoaches and freight wagons out of Groveland, a small mountain town left over from the Gold Rush. It sits astride the Big Oak Flat road into Yosemite.     Read more
