I read the main spillway can handle water flows up to 250,000cfs, the rate is set at 100,000cfs(cubic feet second).

I sent a PM to TL, I'm not sure where He lives in N. CA.

I have been to his house. He is safe. He lives closer to the bay.

The Feather river empties into the Sacramento river.

But that sounds good Carlos, that TL is safe.

As of 7 p.m., Lake Oroville is 100.1 percent of capacity, and the water level is dropping about one-third of a foot per hour.

"The lower it gets the less pressure there will be," KCRA meteorologist Mark Finan said.

The Colusa Unified School District is cancelling school for Monday. While Colusa may not be directly in danger, the schools will be closed "out of an abundance of caution," Superintendent Dwayne Newman said.

Looks like they may have it under control.

I hope. As more rain is on the way, they will have to get the level down PDQ or we will be doing it all again.

130,000 being evacuated.

The BBC says the water has ceased going over the Emergency Spillway.

In Arlington (TX) shooting, ‘It’s just sad that a teenager doing something stupid ends up dead’

The fatal shooting early Sunday of a 17-year-old by what Arlington police are investigating as a vehicle burglary interrupted by the homeowner left some neighbors shaken.
...
Wallace, who has lived in the neighborhood for about six years, said she has not heard of any car burglaries in the area but added that she keeps her car in the garage.

“It’s just sad that a teenager doing something stupid ends up dead,” she said.

The main spillway was able to handle 250,000cfs, however until they fix it, that is no longer the case.

And as if the repairs to the main spillway weren't going to be expensive enough, now they need to work on making the auxiliary spillway sound.

Here is a story about the building of the Dam.

---

If I remember correctly (this early in the morning), part of the Western Pacific Railway's line through the Feather River canyon had to be rerouted at government expense during construction of the dam, the old alignment now being in the lake.

I'm hearing this line, now owned by Union Pacific, is closed and may be for over a month due to flooding. Their other line, the former Southern Pacific over Donner Pass, is also closed due to heavy snow but expected to reopen within days. When I was in Chicago Union Station on Saturday, I heard an announcement that the California Zephyr departing that day would only go as far as Salt Lake City; it normally runs over Donner with Feather River as the emergency alternate.

(Feather River was the original route of the CZ from when it started in 1949 until WP got permission from the government to stop running it in 1970. Passengers from Chicago had to change to an SP train in SLC. When Amtrak started in 1971, it changed to the Donner route to serve more population along the way (but also switched to UP through Wyoming from SLC to Denver because the Rio Grande didn't join Amtrak until 1983 (and then had to keep running through WY for another couple of months because a mudslide formed a permanent new dam that blocked part of the RG at Thistle, UT until they bored tunnels around it)).)

According to what I read, the amount evacuated is 188,000, and CNN is showing crews working overnight to do repairs.

It appears that not only is the main spillway damaged, the emergency spillway is damaged as well. Clearly it is beginning to emerge that the dam was not constructed very well, neither managed, inspected, or maintained properly.

nearly 200,000 evacuated

I just hope that the thing just doesn't go bang, the loss of life and manslaughter charges just don't bear thinking about.

Well, the dam was built 48 years ago.
I would go with possible lack of inspection, first off. One would think that this might have been detectable before a sudden unexpected failure.

At his point, I only hope that they are able to mitigate the damage for now, get things in hand, and then commence on repairs as soon as possible to prevent further damage to the dam itself.

My thoughts go out to all who have been displaced by this event, and hope it does not escalate into a true disaster.

Is it me or https://goo.gl/maps/RGcD4FPFL2M2 shouldn't there have been an abutment built there so the end of the spillway doesn't erode away?

Thank you Ronald Reagan.

Just remember this was the lake 3 months ago.

To have gone from "empty" to over-full in three months must have exceeded the design fill-rate for the dam, so who knows what additional problems are lurking below ground on the "dry" side. To have both the main and emergency spill-ways "fail" in such a short space of time may well be indications of other problems. Remember what this sort of damage must be reducing the "toe mass" of the dam, and that is the lump that actually gives these earth core dams their strength.

I suspect that they, once things are under control again, will need to do some very careful and thorough soil density analysis of the entire downstream side of the dam to determine exactly what the state of things is.
And, I suppose, water content analysis of the soil as well, to determine if leakage through the dam is liquefying the soil, making it ready to give way. Kinda wondering if some earthquake related damage might have created some leakage through the dam itself underground...........

I agree Mark, and such a task will probably need to wait until the water level is substantially below today's

More than a decade ago, federal and state officials and some of California’s largest water agencies rejected concerns that the massive earthen spillway at Oroville Dam — at risk of collapse Sunday night and prompting the evacuation of 185,000 people — could erode during heavy winter rains and cause a catastrophe.
