We advocate for salmon-friendly policies to protect California’s most important run of endangered coho salmon, located in Marin County’s Lagunitas Creek Watershed.

The population of Central California Coast coho salmon has declined more than 95 percent from historic levels, and are now listed as ‘endangered’ under the Federal Endangered Species Act.

Through advocacy, stream protection, and legal action, we’re taking action to ensure the Marin County Board of Supervisors make salmon a priority and take action before it’s too late!

Join us in using science and people power to restore creeks, rescue fish, and change policy.


Take Action!
