California Battles Invasive Golden Mussel Outbreak

Yolo County has officially declared a local state of emergency in response to the escalating threat posed by the invasive golden mussel species. This declaration follows the species' initial detection in North America at the Port of Stockton last October. Since then, the mussels have alarmingly spread northward, reaching West Sacramento just last month, prompting Mayor Martha Guerrero to call for urgent action.

West Sacramento faces significant risks as these invasive mussels infiltrate vital city infrastructure, including drainage pipes and pump stations. Mayor Guerrero expressed deep concern, highlighting the potential for flooding during heavy rainfall if the discharge pipes become too clogged. She emphasized the need for immediate state resources to assist with removal efforts, noting that delays will only increase the cost and complexity of remediation.

The impacts of the golden mussel infestation are far-reaching. Beyond damaging boats and disrupting water infrastructure, they aggressively outcompete native crawfish and other species, diminishing the food sources for local wildlife. Some research also suggests a link between these mussels and toxic algal blooms, adding another layer to the ecological threat.

Officials are requesting public assistance in identifying and reporting any sightings of the golden mussel. This can be done through the California Department of Fish and Wildlife's "Report an Invasive Species Sighting" page, via email to Invasives@wildlife.ca.gov, or by calling 866-440-9530.
