New Emergency Siren Installed at Dam that Forced Evacuations

Officials say they have installed a new emergency siren at a Northern California dam whose damaged spillway forced evacuations earlier this year. The state Department of Water Resources says it will conduct the first test of the new siren at Oroville Dam on Friday. Monthly tests in July and August will follow. The previous siren was lost during water releases in February. Construction crews have begun demolishing the destroyed portion of the main spillway at the dam, which is the nation’s tallest.
