Five Years of Cleaning up the Sierra

During the first five years of the Great Sierra River Cleanup, nearly 19,000 volunteers have joined together to remove almost 600 tons of trash and recyclables from watersheds throughout the Sierra Nevada. Hundreds of community groups have spread across 22 counties and over 1,700 river miles to pull appliances, cigarette butts, beverage cans, baby diapers, tires, furniture, and more from the rivers and streams that supply the State of California with more than 60 percent of its water. This effort, in partnership with the California Coastal Cleanup Day, serves to promote good stewardship on all of our waterways, from the source to the sea.

Thank you to our generous sponsors for their support of the Great Sierra River Cleanup!

Why is it important?

The Great Sierra River Cleanup is about much more than picking up trash. It’s a day for Sierra communities – and those from all over California – to demonstrate their desire for clean water and healthy rivers. It’s an opportunity to learn about California’s water source and it’s a time to come together with your families, your neighbors, your community, and your friends to accomplish something vital and worthy on behalf of our great Sierra rivers.
