Millions of Californians could end up with higher water bills after the Trump administration on Friday announced that federal emergency officials aren’t going to reimburse the state for $306 million in repairs to Oroville Dam stemming from the 2017 spillway crisis. The Federal Emergency Management Agency said federal taxpayers shouldn’t have to pay for problems that existed prior to a massive hole forming in the dam’s concrete spillway in February 2017, eventually prompting the two-day evacuation of 188,000 downstream residents and a $1.1 billion emergency response and repair job.
