The waters around the Port of West Sacramento just became ground zero for one of California’s fastest-moving environmental crises. California Department of Fish and Wildlife officials have confirmed that invasive golden mussels have been discovered in and around the port—marking the northernmost location where these destructive mollusks have shown up since they first arrived in Stockton in 2024.
If you’re thinking,“It’s just mussels, how bad can it be?”—buckle up. These creatures are ecological saboteurs. They clog water pipes, destabilize food webs, and wreak havoc on aquatic ecosystems. And here’s the kicker: they’ll attach to virtually anything underwater, including boats. Which means every vessel that leaves West Sacramento could be a floating delivery system, spreading golden mussels throughout the Delta like some kind of biological Uber.
That’s why officials are issuing an urgent call to action for anyone who uses the water. If your boat, dock, or recreational equipment touches the water, you need to clean, drain, and dry it thoroughly. It sounds simple, but it’s the difference between containment and catastrophe. Sacramento County has already declared a state of emergency over the invasion—a declaration that underscores just how serious this has become in just two years.
What started as an isolated problem in Stockton has now crept north into our backyard. The golden mussel’s relentless march up the valley is a stark reminder that invasive species don’t respect county lines or shipping routes. They follow the water, and the water connects us all. The question isn’t whether you should care about this—it’s whether you’re willing to take the five minutes to clean your boat and help stop the spread.
