Been reading some of the news about this. It was built in the 1950's, no real problems or repairs since. They passed a $7.4 billion dollar water bill in 2014, not a single dollar spent on the Oroville dam. It is a earth dam, not concrete.
I suspect it was put on the bottom of the list for any serious money because it wasn't a problem. Normal for many Gov organizations.
Cal will probably have an emergency tax increase/spending spree/debt increase. Because of the inflated land values it will be a staggering amount of money.
