Marin County’s two largest water suppliers say they have dam safety strategies in place but intend to update their hazard mitigation plans in the near future. The utilities were responding to a Marin County Civil Grand Jury report urging the agencies to prepare for more intense “atmospheric river” storms caused by climate change. Both agencies are required to provide responses under state law. The June report said the seven dams managed by the Marin Municipal Water District and the one dam managed by the North Marin Water District are in compliance with regulatory standards.
