Join Sierra Nevada Alliance and our host sites throughout the Sierra Nevada for the Great Sierra River Cleanup (GSRC) on Saturday, September 21, 2024.

GSRC is a Sierra-wide watershed cleanup event coordinated by Sierra Nevada Alliance in collaboration with California’s Coastal Cleanup Day.

Last year, 633 volunteers removed 7,402.5 pieces of trash from 98 miles of Sierra Nevada waterways. We’re looking to expand our efforts to make an even greater impact.

You can be part of the solution and volunteer to help remove litter and plastic pollution from our beloved Sierra Nevada watershed.

The Great Sierra River Cleanup (GSRC) is one of many California Coastal Cleanup Day events. Previously hosted by the Sierra Nevada Conservancy, the Sierra Nevada Alliance is very excited to take the reigns as the GSRC coordinator, and to continue the statewide effort to reduce plastic pollution and litter in and around our Sierra waterways.
