The golden mussel, an invasive species that is making its way across the delta, through waterways and pipes, is now reaching as far south as Riverside County. … On top of concerns that farmers won’t be able to pump water during the dry months, it also poses a flooding threat to urban areas. … Action is already being taken at the county and state levels. The San Joaquin County Board of Supervisors created a local golden mussel committee to help communicate better with state and affected areas in the county. The state has also secured $20 million in this year’s budget to combat the spread and support local prevention efforts. In the meantime, these small invaders are here to stay.
