Calif. Cuts Golden Mussel Safeguards At Vital Reservoir, Alarming Experts [1]
"Destructive golden mussels are wreaking havoc in California waterways. Why are California water managers ending precautions for a vital reservoir?"
"The state of California is walking back protections meant to keep destructive golden mussels out of Lake Oroville, one of the largest and most important reservoirs in the state.
The move follows a new state-funded risk assessment that the invasive species poses a lower risk to the lake, which water managers say changes the state’s calculus on costly and difficult measures aimed at keeping the invaders at bay.
No state agencies or scientists have found mussels in Oroville yet. But invasive species experts say the revised policy of the Department of Water Resources increases the likelihood that golden mussels will invade Lake Oroville and hitch a ride on boats to other lakes. They disagree, though, about whether preventing such an incursion is even possible.
”California is under an epidemic of golden mussels,” said Anthony Ricciardi, a professor of biology and the director of the Bieler School of Environment at McGill University. “Like in any epidemic, you got to control the key hubs — or else the war is lost.”"
