Mayors: California Not Operating Damaged Dam Safely

California is putting communities downstream in danger of flooding with the way it runs the now-crippled Oroville Dam, mayors and county leaders wrote this week in a strongly worded letter to Gov. Jerry Brown. The letter — signed by mayors of the city of Oroville and six other communities downstream, county leaders, state lawmakers and others — comes in the wake of a February spillway emergency at the dam that forced the evacuation of 188,000 people.
