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.
