California Gov. Jerry Brown held his first news conference in February on the Oroville Dam emergency after the threat of lake Oroville sent nearly 200,000 people from their homes. The governor defended the state’s handling of the crisis, while asking for federal assistance for the emergency. Now, about two months after declaring a state of emergency in Oroville, Brown’s administration is blocking a public review of records relating to what happened when the spillway began eroding, how it was maintained, and the crisis aftermath.
