State Declines Emergency Declaration Over Golden Mussel

Live Poll

Should the state provide emergency funding for the Golden Mussel invasion?

California's Office of Emergency Services declined to issue a Governor's State of Emergency proclamation and denied Kern County's request for California Disaster Assistance Act funding to combat the Golden Mussel invasion. The invasion continues to clog agricultural water works in the Central Valley.

Why it matters

The Golden Mussel is costing Kern County farmers an estimated $36 million annually, and local water districts will not be reimbursed for efforts to keep waterways clean and secure. The state's decision means counties must absorb these costs while two federal bills that would provide more funding remain unpassed.

The state's decision rests on the finding that no viable path to permanent restoration exists, a point the Office of Emergency Services used to rule out both the proclamation and CDAA funding. Kern County Supervisor Jeff Flores projects annual costs will climb to $50 million if the state delays, while the full scope of damage across affected waterways has not been quantified in the source material.

The players

California Office of Emergency Services

The state agency responsible for coordinating emergency response and administering disaster assistance programs, which determined current conditions do not warrant a Governor's State of Emergency proclamation or CDAA funding.

Jeff Flores

Kern County Supervisor who has pushed for a countywide emergency declaration and warned that costs could reach $50 million a year if the state delays action.

The details

Kern County requested emergency funding after the Golden Mussel was first detected in its waterways last winter in the Arvin Edison Water Storage District. Current response efforts include detection, controlled chemical pumping, and monitoring to determine whether treatment is working, with the county documenting costs and receipts as districts treat the mussel.

Last spring: Supervisor Jeff Flores began efforts to declare a countywide emergency.

Seasonal Patterns

The state's denial applies the California Disaster Assistance Act's requirement of a viable path to permanent restoration to an invasive species outbreak rather than a sudden natural event. The ruling places this infestation within a funding framework that has historically reserved CDAA support for discrete disasters with recoverable outcomes.

Water districts and agricultural operators in affected counties should document all treatment costs and receipts, since reimbursement from the state is not currently available. Residents who rely on irrigation water in the Central Valley should watch for updates from their local water district about treatment and any changes to access.

The takeaway

Invasive species threats can impose recurring costs on local economies that fall outside traditional disaster frameworks, so farmers and districts facing them should track expenses carefully and monitor pending federal funding legislation.
