2017-02-13 -Signs, Portents, and the Weather-
Fearing collapse of emergency spillway at Oroville Dam, Oroville evacuated
I certainly hope no brown smelt are harmed.
[SACBEE] 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.
"And this time - no ark."
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.

Chris Orrock, a front man for the Department of Water Resources, told The Bee the failure happened as the bottom of the emergency spillway began to erode.

"It happened quickly," he said.

Sutter County also put out an alert on Facebook:

We have received information about the potential for increased flows in the Feather River of as much as 100,000 cubic feet per second. We are gathering as much information as possible and will be providing additional information as soon as it is verified.

#3 as of earlier this am, national guard are on standby and there has been some repair work on the emergency spillway

basically, they need lots of boulders placed on the spillway

#4 FOX news sez 'much repair work has been done, officials are encouraged, some people are being permitted to return. More rain coming Thurs and Fri.'

#7 The moral of the story is: Don't build your house in a flood plain...especially if the dam was built in California.

#8 This is just part of the plan to release water for the delta smelt, right?

#9 Just did some googling of the Oroville Dam. It's built on the Feather River which, it turns out, is the main tributary to the Sacramento River. The Sacramento River flows right through, you guessed it, Sacramento which is the California state capitol. So none other that Moonbeam himself and all the loonie legislators and bureaucrats are directly downstream from the Oroville Dam. Now I've heard about draining a swamp but I wonder if flushing it might have the same effect.

#13 the emergency spillway seems to be several hundred feet long and the damage seems to be at least 30' wide

that will require somewhere near 200-400 truck loads of boulders - seems like they really ought to be able to take care of that as today, tomorrow and most of Wed will have good weather

I don't know how they could fix the regular spillway quickly because they are using it to remove water as fast as possible from the reservoir.

unfortunately, the Feb 16-20 storms look to be significant rain events for the basin

Funding may be the problem. If I owned a trucking company, I'd be asking for up-front payment. Brown is currently begging for federal funds. You know the old saying about 'money talks'... the other stuff walks.

#16 I underestimated the length of the emergency spillway- its 1700' long

also, the damaged area next to the spillway seems to be more like 100' to 200'

so they need thousands of truckloads of boulders, not hundreds

#17 Lord Garth, that's the main spillway. The emergency spillway starts just to the north-west and ends near the corner of the boat ramp parking lot. See this google maps picture.

Word this morning was that they were going to helo it in and dump it.

#21 That's an awful lot of hydro-electricity going to waste.

It seems the dam is used for pumped electricity storage. I wonder how recently it was used for this, and how much the water level was increased.

#22 Unlike conventional power systems, renewable power isn't matched to demand, and there are frequent large surpluses. Which get 'stored' in pumped hydro dams like this one. It would not surprise me if this was a contributing cause of the current situation.

#27 Rantburgers, while I appreciate the opportunity to poke fun at the incompetent government of California, this is a problem.

The first picture in this news article shows the real an imminent danger to the damn dam.

The erosion on emergency spillway is about 50 feet from busting the dam. This erosion was due to less than a day of use. That means 100 feet of water on Oroville, and 10 on Yuba City.

It is going to rain 4" in two days. This thing is an unequivocal emergency situation. Every single truck in California needs to be putting rocks and fill into this hole. Right now. If the water ever gets up over the emergency spillway before it is filled, there are just a few hours before something like a cubic kilometer of water comes down stream. And 50 more if the dam itself is compromised by further erosion.

Keep these unfortunate folks in your prayers.

#28 This is red state part of CA, not that it should make any difference. Been tracking this since Friday. It has not been fun, nor funny in the least.

This has been handled very professionally. Support is important right now

#29 One Fire truck can pump 1,000 gallons a minute. Some trucks more. That is 60,000 gallons an hour.

Every fire department in the region should send at least one truck to the area as mutual aid in getting as much water out of that body of water behind the dam as possible.

Pumpers (what firemen call their trucks) should stay during the two day rain continuously pumping.

This is something only firemen know about so people should get the word out about this approach.
