This is hard to believe. The main spillway couldn't handle the pressure of a designed release, and failed dramatically. Now the auxiliary (emergency) is operating, and not well. Same issues with concrete not being able to take the pressure. In desperation, they are now releasing as much as they can onto the damaged spillway. It is really bad news as undermining is occurring on multiple fronts.
How does this happen? I know the structure design is 50 years old, but come on. Floods are well known in CA history. They knew this kind of flooding happens frequently enough. And now it can't handle it. Scary.
Here in NC we had similiar spillway failures recently with Hurricane Matthew, but these were on private small lakes. Not a major flood control and generating public project!
Prayers and good thoughts to all those possibly affected. Be careful out there.
BREAKING: Marysville, Yuba County evacuated as Oroville spillway collapse feared | The Sacramento Bee
The Butte County Sheriff’ Office released the following statement on Facebook:
This is an evacuation order.
Immediate evacuation from the low levels of Oroville and areas downstream is ordered.
A hazardous situation is developing with the Oroville Dam auxiliary spillway. Operation of the auxiliary spillway has lead to severe erosion that could lead to a failure of the structure. Failure of the auxiliary spillway structure will result in an uncontrolled release of flood waters from Lake Oroville. In response to this developing situation, DWR is increasing water releases to 100,000 cubic feet per second.
Immediate evacuation from the low levels of Oroville and areas downstream is ordered.
This in NOT A Drill. This in NOT A Drill. This in NOT A Drill.
