Yosemite is Not for Sale
A developer wants a route through Yosemite National Park to reach an 83-acre parcel near Big Oak Flat Road — opening the door to resort development upstream of the water millions of us depend on. Add your name and tell decision-makers our park is not a bargaining chip.
Ballot Measure · Vote by Nov 3
Vote no on Prop 45
Prop 45 would put a stopwatch on California's bedrock environmental review law — capping reviews of major projects at one year and rushing the court cases that hold them accountable. Our rivers deserve a careful look, not a race to the finish.

We're preparing a letter campaign to put our rivers on the Governor's desk. Be first in line when it opens — we'll send you everything you need to add your voice.
Run Wild Yosemite
The river came home
This September, the Tuolumne flowed into a brand-new bend near La Grange. Crews built it over the summer so salmon have somewhere to come home to. It's one real step toward rivers that run wild again, for salmon, for wildlife, and for the 3 million Californians who drink their water.
Do you know where your tap water comes from?
If you live in the Bay Area, it starts as snowmelt in the Sierra Nevada — and travels 150 miles by gravity alone to reach your glass. Download our free What's in Your Water report to learn more.
the issues
our work tackles head-on
Our region faces real challenges — for rivers, wildlife, and the people who depend on them.
Rivers that supply clean water to millions are stressed by drought, pollution, and climate change.
Critical wildlife and salmon habitat is disappearing, threatening the species that depend on these rivers.
Overgrown, fire-prone forests put communities, water supplies, and ecosystems at risk.
Many people — especially youth — lack access to nature and opportunities to learn, explore, and lead.
Communities want to protect the places they love but need clear pathways to take meaningful action.
Every one of these challenges is solvable — but only with people behind the work. That’s where you come in.

Our mission
To protect and restore Yosemite’s rivers so people, wildlife, and communities can thrive.
As climate change, drought, and habitat loss threaten the rivers that sustain millions, our region faces growing risks to clean water, forests, and biodiversity.
We unite conservation and community to restore habitat, strengthen forest resilience, and advocate for strong river protections.
The result is a healthier, more resilient watershed where clean water flows, wildlife returns, and communities are empowered to shape their future.
