The LA Times reports that the Federal Aviation Administration has issued a complete no fly zone at the Oroville Dam.
As new storms approach, the threat of rising water levels and further flooding continue, however officials are optimistic that the risk of flooding has dropped significantly.
Earlier drone footage of the emergency overflow being released from the dam is available here.
The FAA flight restrictions ban aircraft operations, including recreational drones, with a trapezoidal shared zone surrounding the dam to a height of 4,500 feet. The ban is in effect until May 17th, as emergency crews and do their own aerial surveillance of the dam including helicopter operations moving boulders into place to help prevent further erosion of the spillways.
