Our plan
Restoring Hetch Hetchy, Yosemite Valley’s lost twin, to its natural splendor is an extraordinary and compelling opportunity. It is also challenging. San Francisco must be convinced or compelled to make improvements to its water system so there is no loss of supply, i.e. Hetch Hetchy Reservoir must be relocated.
The challenge is well worth it. We can recreate a majestic glacier-carved valley with towering cliffs and waterfalls where river and wildlife run free.
Hetch Hetchy can be a new kind of national park, with limited development, an improved visitor experience, shared stewardship with native peoples, and permanent protection of its natural and cultural heritage for future generations.
What is Hetch Hetchy and why restoration is important?
Hetch Hetchy was once a majestic glacier-carved valley and home of Indigenous peoples; its beauty famously compared to Yosemite Valley.
The only location in America’s national parks developed for one city’s municipal use.
We have an opportunity to return Hetch Hetchy to its natural splendor, and to create a new national park.
Help us build support to restore Hetch Hetchy.
