Meet Yosemite Rivers Alliance

For over 40 years, we’ve protected the Tuolumne River. Now, our alliance expands to safeguard the Tuolumne, Stanislaus, and Merced — three rivers that sustain life from the Sierra crest to the Pacific Coast.

Formerly Tuolumne River Trust — same heart, bigger impact.

We’ve grown to reflect the true flow of our work.

After four decades as Tuolumne River Trust, our mission has evolved beyond one river.

The challenges facing our region — wildfire, drought, declining salmon runs — don’t stop at watershed boundaries.

That’s why we’re uniting as Yosemite Rivers Alliance: to protect the interconnected rivers, forests, wildlife, and communities that keep Yosemite, and California, flowing.

What We Protect, Together

From Sierra headwaters to Bay Area taps, our work flows through four connected pillars.

Clean Water Connection

Your tap water flows 160 miles from Yosemite. We protect that journey.

WILDLIFE
PROTECTION

Over 600 species depend on the rivers we restore and the lands we defend.

Recreation & Adventure

Healthy rivers keep our outdoor adventures flowing — rafting, hiking, fishing, and beyond.

From classrooms to mountain meadows, we train and employ the next generation of river stewards.

Community Engagement

Because Yosemite flows through every part of life here.

The water that fills your glass, the salmon that return each fall, the forests that shield us from fire — they’re all connected.

three rivers | one alliance

This is more than a name change — it’s a call to action.

Join a growing alliance of people who love these rivers and believe in their power to sustain life and community.
