Tiny Mussels Invade California Waters
25 Nov
Summary
- Golden mussels, small invasive mollusks, have been found in Northern California.
- These mussels pose a threat to infrastructure and ecosystems in waterways.
- Boaters can help prevent spread by cleaning, draining, and drying watercraft.
A significant concern has emerged across Northern California's waterways with the discovery of golden mussels. These tiny, invasive mollusks, first identified in North America in October, have established themselves in crucial water bodies, including the Sacramento-San Joaquin Delta and San Luis Reservoir. Their rapid spread poses an "urgent invasive species threat" to the region's delicate ecosystems.
These non-native mussels, originating from China and Southeast Asia, are believed to have arrived via international shipping. Once established, they form dense colonies that can severely disrupt vital infrastructure. Clogged pipes and damaged boat motors are among the immediate problems, with potentially substantial financial implications for maintenance and operational upkeep of water systems.
The California Department of Fish and Wildlife is implementing a plan to manage this invasive species. Public cooperation is vital, with boaters encouraged to practice "clean, drain, dry" protocols for their watercraft to prevent further dissemination. Residents who spot suspicious mussels are asked to report them to the CDFW to aid in containment efforts.
