Oroville Dam Repairs Aren’t Enough, Feds Warn. Should State be Forced to Plan for a Mega-Flood?

Federal regulators are raising new concerns about the troubled Oroville Dam, telling California officials their recently rebuilt flood-control spillways likely couldn’t handle a mega-flood. Although the chances of such a disastrous storm are considered extremely unlikely — the magnitude of flooding in the federal warning is far greater than anything ever experienced — national dam safety experts say the Federal Energy Regulatory Commission’s concerns could have costly repercussions for California. The public agencies that store water in Lake Oroville may be forced to spend millions of dollars upgrading the dam.
