Our Events
We host regular creek clean-up and restoration events where volunteers gather to pick up litter, remove invasive plants, and monitor water quality. These events are a great way to make a positive impact on the environment while also getting to know your local community.

Living Arroyos volunteers have planted more than 8,000 native plants near our waterways.

Living Arroyos volunteers have removed 24,000 gallons of trash from our waterways.

Join the over 3,000 volunteers who have donated their time to the Living Arroyos program!
Internships
Living Arroyos offers paid internships to college students and recent graduates to give them hands-on training in riparian restoration.


Adopt a Creek
Join the Tri-Valley’s families, companies, and community groups who have adopted a local creek. Together, we can create a cleaner and healthier future for everyone!
Why Clean Creeks Matter
Healthy creeks indicate a thriving ecosystem. They provide clean water for drinking, irrigation and recreation, and are home to many plants and animals. When our creeks are polluted, it affects not just the creek itself but can lead to larger environmental issues.
