A growing invasive species threat is gaining significant attention at both the State Capitol and among California water agencies.

Golden mussels is an invasive shellfish species capable of rapidly attaching to and clogging pipes, pumps, canals, flood control systems, and other critical infrastructure that continue spreading throughout California waterways, prompting increased calls for coordinated mitigation and prevention efforts.

According to KMPH News, water agencies across the state are implementing preventative measures and discussing long-term impacts to water delivery systems, recreation, agriculture, and Delta infrastructure.

“Golden mussel has quickly taken center stage in water management conversations,” said Katie Patterson with South San Joaquin Irrigation District.

The invasive species was first detected in California in 2024 and has since spread through portions of the Sacramento-San Joaquin Delta and connected water systems. Officials warn the mussels reproduce rapidly, colonize hard surfaces, restrict water flow, damage infrastructure, and may contribute to harmful algal blooms.

State agencies continue encouraging the public and recreational boaters to follow the “Clean, Drain, Dry” protocol to help slow the spread of invasive mussels between waterways.
