Reading Summary: Kern County Extends Local Mussel Emergency Declaration

Key Facts

• Local water districts have spent $7.3 million to date fighting golden mussels, with costs projected to reach $36 million per year
• The Kern County Board of Supervisors extended its local emergency declaration by 60 days on July 14
• Golden mussels (native to Southeast Asia) entered California via cargo ship ballast water released into the Sacramento-San Joaquin Delta in 2024
• The mussels have spread from the Delta to San Diego, documented by a CDFW interactive tracking map
• San Joaquin and Sacramento counties have also declared local emergencies

Who Is Affected

• Kern County Water Agency and Friant Water Authority (both have active task forces)
• Water districts across the Central Valley and as far south as San Diego
• The broader Sacramento-San Joaquin Delta ecosystem
• State taxpayers potentially on the hook for reimbursements via California Office of Emergency Services

Policy/Legal Angle

• No statewide emergency declaration has been issued by the Governor, which is blocking faster reimbursement access
• Kern County has submitted costs to the state Office of Emergency Services (Cal OES) in anticipation of future reimbursement
• No specific statutes or court decisions cited, but the emergency declaration framework is central to the funding mechanism

1. Why hasn’t the Governor declared a statewide emergency? With three county declarations, $7.3M spent, and a $36M/year projection, what is the political or bureaucratic holdup — and who bears the cost in the meantime?
2. How did ballast water from cargo ships go unregulated? This is a clear invasive species pathway — what existing laws govern ballast water discharge in California, and did they fail here?

Kern County extends local mussel emergency declaration

Local water districts have spent $7.3 million, and counting, trying to eradicate the rapidly spreading invasive golden mussel, according to a report delivered during the Kern County Board of Supervisors July 14 meeting.

Water districts are expecting those costs to balloon to $36 million a year, according to a report by the County Administrative Office.

The board approved extending its local emergency declaration by another 60 days regarding the mussels and renewed pleas for the Governor’s office to declare a statewide emergency.

“I want to implore the governor and the state Legislature to hear not just Kern County’s cries for help but the entire Central Valley and the state,” said Supervisor Jeff Flores. “We need that state declaration of emergency so we can start capturing that money now. Every day that goes by, every week that goes by, the situation just gets worse.”

Kern has already submitted water district costs to the state Office of Emergency Services, which could be reimbursed later if a statewide emergency is declared, according to the CAO’s office.

San Joaquin and Sacramento counties have also declared local emergencies. The Kern County Water Agency and Friant Water Authority both also have task forces to monitor the spread of the mussels, which have been found in those agencies’ critical infrastructure.

The mussels, native to south east Asia, are very small, repopulate quickly and can clog the insides of pipes and other water equipment.

They, apparently, hitchhiked to California in cargo ship ballast water, which was released into the Sacramento-San Joaquin Delta in 2024.

They have since spread throughout the state’s water systems all the way to San Diego, according to an interactive map created to track the mussels by the California Department of Fish and Wildlife.
