Golden mussels pose a serious and fast-growing threat to California’s water infrastructure. As the operator of the State Water Project (SWP), DWR is deploying a comprehensive strategy to mitigate the impact of golden mussel infestation and prevent further colonization. DWR is attacking the problem through several immediate response measures, concentrated investments to strengthen infrastructure, and long-term research and partnerships to improve the state’s ability to manage golden mussels. … DWR is pursuing emergency registration of potassium chloride (potash) as an additional treatment option. It is effective at controlling adult golden mussels and is safe for fish and wildlife at treatment concentrations.
