Golden mussels are an invasive freshwater species not yet detected in the Eastern Sierra, and keeping them out is critical.

They spread primarily by hitchhiking on boats, trailers, and gear that move between lakes and rivers. Once they are here, they are impossible to remove.

New ordinances in Mono and Inyo Counties require inspections before launching any trailered watercraft, including boats and jet skis, into any body of water.
