Please join the Sierra Nevada Alliance and our host sites throughout the Sierra Nevada for the Great Sierra River Cleanup (GSRC) on Saturday, September 23, 2023.
The Great Sierra River Cleanup is a Sierra-wide watershed cleanup event coordinated by Sierra Nevada Alliance in collaboration with California’s Coastal Cleanup Day.
Last year, 249 volunteers removed 5,711 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 Neavda watershed.
