Assemblymember Rhodesia Ransom warned Wednesday that California is running out of time to contain the rapid spread of invasive golden mussels, urging immediate state action to protect water systems, agriculture and consumers. Speaking during a state budget subcommittee hearing, Ransom called for funding to establish five decontamination centers in the Sacramento-San Joaquin Delta, which she said is critical to slowing the species’ expansion into other waterways. … Golden mussels, first detected in California in 2024, spread by attaching to boats and water systems, clogging pipes and damaging infrastructure.
