Restoration relies on relationships.
Centuries of fractured connections degraded our watersheds. Repair starts with bringing people back together — even those who have not always seen eye to eye.
Why Partnerships?
Restoration projects can only succeed when they’re built on a foundation of trust.
Community has been at the heart of CalTrout’s work since day one — and over more than 50 years, we have built a reputation for bringing people together, even those who do not always see eye to eye.
Every project we take on starts with building trust and collaboration, and none could succeed without them.

Our Partners
A community of action built over 50 years — and growing every day.
We have decades-long partnerships that have already moved the needle for California’s rivers. We are also constantly building new relationships — with agencies, universities, NGOs, Tribes, politicians, community members, landowners, farmers, ranchers, donors, volunteers, and many more.
Agencies
We are a trusted partner to state and federal agencies, helping direct public funding to high-impact projects while working together to achieve shared conservation goals.
Tribal Nations
This work is deeply meaningful to California’s Tribal Nations, and we strive to build lasting partnerships that respect Tribal knowledge, support Tribal priorities, and create opportunities for collaboration at every stage.
Universities
We partner with leading universities to ensure our restoration and policy work is grounded in the best available science and informed by the latest research.
NGOs and Coalitions
We bring together nonprofit partners and coalitions to align expertise, strengthen advocacy, and tackle watershed challenges that no single organization can solve alone.
Landowners, Farmers, and Ranchers
We work alongside private landowners and ranchers to develop practical, voluntary solutions that improve working lands while restoring healthy rivers and streams
Local & Federal Decisionmakers
We provide trusted science, on-the-ground experience, and practical solutions that help decisionmakers craft policies and investments that benefit California’s freshwater ecosystems.
Donors and Members
Our donors and members make this work possible, investing in science, restoration, and advocacy that deliver lasting benefits for fish, water, and people.
Community Members
Healthy rivers depend on engaged communities, and we create opportunities for people to learn, volunteer, advocate, and help shape the future of California’s watersheds.

Engaging communities
Restoration on the ground. Stewardship as culture.
When we invest in and partner with communities, the impact of restoration grows. Our work extends beyond projects on the ground — it ripples out across California, engaging schoolchildren, university students, film festival audiences, community event attendees, and many more. We know that removing a dam or restoring a riverbed has no lasting effect without a culture that centers the environment, so we create opportunities for people to come together — through education and celebration — to build strong local cultures of conservation.

In their Words
“I’m so thankful to organizations like CalTrout that are engaging thousands of Californians in protecting their watersheds. Most Californians and Americans don’t know where their water comes from. CalTrout and others are changing that by engaging people, getting people out onto rivers, and helping them understand what they can do to protect them.”
Secretary Wade Crowfoot/California Natural Resources Agency

WATCH · PARTNERSHIP in action
Ranchers, Tribes, and scientists come together to restore the Shasta River.
In California’s Shasta Valley, salmon once filled the river from bank to bank, but today many have disappeared. Now, ranchers, fisheries professionals, and Tribes are working side by side to bring them back.
