California's Lake Oroville Main Spillway Severely Damaged/Eroded. Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed

Without control of the gates and no ability to release in volume....

This thing is a disaster waiting to happen.

With ongoing leaks it could fail at any time, at any level.

Just saying hi. Not really logged in but this is paradise gypsy here. Went thru Oroville about a week and a half ago. Thought about going up to walk across the dam since it was a Sunday evening. Realized I was absolutely terrified to do so and right there is my opinion about the dam. Hi to all and hope you are well. I pop thru often on here.

The inundation maps are based on a full 900'elevation, fair weather and complete catastrophic dam failure. Instant release of the total reservoir storage (like the St. Francis Dam disaster).

Lower reservoir elevation coupled with a gradual release like a slowly failing spillway would reduce the inundation area, as the water would have more time to move downstream instead of spreading out.

The only scenario that concerns me would be a wet season catastrophic failure at full elevation.

The river would already be high, creaks and streams overflowing and the ground already saturated. That would increase the inundation area significantly.

ANY NEW UPDATE...?

PINE FLAT STILL AT 175% OF HISTORICAL AVG..THEY ARE HOARDING THE WATER...CHECK THE OTHER SITES!@

Water is the new gold rush in California. Except only the government has claims.

OROVILLE DAM FINALLY BELOW 845..BUT..STILL NEED LIKE 28 MORE FEET OT DROP TO FIX THE GATES...SHIT!@

Hum. I don't know what to say. The thing is, if they don't dismantle the dam before winter and you get pummelled with rain, and they are afraid to open the gates but the HPP can't keep up with inflow, then you might get that catastrophic failure at full elevation. I don't know what to do but pray for everybody, and I know a drought isn't good for CA but maybe for this dam it would be a mercy.

The Emergency Spillway is intended to prevent the dam from overtopping and thus preventing a catastrophic failure of the dam. However, there are issues with the dam itself and the main spillway that could cause such a failure. Settlement, seepage, etc.

The drought-flood cycle in California is hard on earthen dams. Years of drought and low water levels allow fill materials to shrink and crack. Then a flood season and high inflow puts tremendous pressure on the dry, shrunken structure.

Proper flood storage procedures by DWR could reduce these impacts, but they have proven to be incapable of proper reservoir management in the past.

It is interesting to note that evacuations were ordered in 1997 because there were concerns the ES MIGHT be overtopped due to high inflow. Thankfully, no overtopping occurred, but Oroville, Marysville and Yuba City were evacuated for days.

In 2017, officials KNEW the ES was going to be overtopped, but evacuations were not issued until AFTER the ES overtopped and the erosion (that a child could have predicted) was occurring.

Why the disparity?

I have absolutely no trust in CA DWR. I have earned that right.

Hmm exact;y how would they dismantle this dam? and before winter at that.

the catastrophic failure will likely be in the seam between the dam and the abutment that has the spillways on it... But it could blow on that abutment too.. or flat in the middle of the dam itself.

OROVILLE RULEZ!

I hope this is too far away to have much impact on the Oroville dam.

From the earthquake thread:

Magnitude 6.3
Region OFF COAST OF OREGON
Date time 2019-08-29 15:07:59.0 UTC
Location 43.66 N ; 128.06 W
Depth 10 km

It's weird I didn't feel a thing.I am very close on the coast of Oregon. Nothing.

10.0 Magnitude Earthquake prophesied for California before the end of Summer, 2019.

[link to youtu.be (secure)]

I have read this man's testimony.

I believe that he is telling the truth.

He has no reason to lie.

Watch the video. Decide for yourself.

In a magnitude 10.0 earthquake, it is likely that all of the California dams will fail, not just Oroville.

Doing ok with Swedes Fire, Crunch?

Yes, it is in the foothills to the east.

We are fine down here in the floodplain.

In other news, the reservoir elevation is down to about 828 feet. Still churning out through the Hyatt Power Plant.

A far cry from what DWR Spokesperson Erin Mellon stated back in April (?) about keeping the lake at full 900' elevation all summer.

I'm still trying to find a link to that statement. It seems they all disappeared.

Crunch- Mellon's lie was in various places on the internet; we all remember. I remember the posts also about the dam guidelines, keeping it at 850 to be safe.

What creeps me out the most is the total disappearance of weiryone on twitter with all of his fabulous pictures. He must have been severely threatened.

Wonder how wet the winter will be.

It is highly possible the southern SA is going to move big time.

a few days ago now.. there was a shit.. words tonight.. but a 7 hours recording.. of a type I used to watched years ago.. a tremor type recording.. on Cajon pass. This is ominous. This type of "tremor" at this level precedes major quakes in a couple weeks or so..

Last time.. was 2 weeks before those last quakes that are still rattling near Ridgecrest I think it is... and that one before Ridgecrest was not as heavy as the one a few days ago on Cajon Pass.

I was going to include Mellon's statements in a reply to DWR's email, but but they seem to have been scrubbed. I can't find her comments anywhere.

re: weiryone. I imagine photos of the dam could be considered by TPTB to be a national security issue.

A cease and desist order under the threat of domestic terrorism charges would be enough to make anyone drop out of sight. Just a theory.

Good morning Orotards.

This catastrophe has not gone away.

ORION have anything to do with ZION?

NOPE nothing at all in that regard...

No, it has not gone away. It is simply building more disaster potential the longer it continues to exist.

The local forecast is showing a chance of rain next week.

Here we go, into the wet season.

DWR hasn't got it below Oroville reservoir spillway gate elevation yet, I hope they are puckering.

Bastards.
