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

Lots to hide. It is criminal.

And yet, the damn dam is STILL fine...

All this kvetching from uneducated ssi recipients in Peoria...

ON TIME
UNDER BUDGET

-Kiewit (theres a readon we have 3 digit contractor’s license number...

Dams are fine until they blow and this one is not fine. I know this. I was provided an education when the spillway went from some experts in Dams that i know.

IT LOOKS LIKE THE DAM IS READY TO COLLAPSE!

I know Oroville seismometer like brother.

Here is how we fix Z for you last year. It is vault! Stay out. No bat. OK, I just look, not fix.

I have proofs Oroville seismic working fine. Broadband net OK show but not USGS show? SQUAK! WHAT?

Dam not fine.

FAR from Peoria, but in the damage path of Oroville Dam.

On time? Over Budget and incomplete.

Kiewit is as wasteful as any other 3-digit contractor. My neighbor brings shit home from the job you would not believe.

Lumber. Steel. Tools. Cable. Hardware. Shipping containers. All Kiewit yellow. He uses the company truck for his personal vehicle.

The Oroville job is over budget and incomplete. Kiewit needs a microscopic anal audit. Waste and theft are rampant.

WE GOT A NEW MYSTERY....... @ 814.17

IT IS TWO THIRDS FULL AND AT 80% OF ITS HISTORICAL AVERAGE.

LOOK AT THE DAILY CHART ...NONE OF THE OTHER ONES ARE THAT LOW! THE DAMMED DAM IS NOT SAFE..THEY KNOW IT ..AT ANY SPEED..LIKE RALPH NADER SAID!....

SQUAWK! SQUAWK!

What THIS? Shadee as hells. DWR tricks out? You pay NOW.

Legal mumboes and jumboes make head explode.

Help to translate for you good Chinese friend.

Water on the top cam today.... lower cam is off. Its not real heavy but across most of it.

OROVILLE NOT HAPPY WITH YELLOW RIVER DAM GETTIN ALL THE PRESS!

804.29

63 PERCENT FULL AND 77 OF HISTORICAL AVERAGE...THEY 'KNOW'!

Did the quake today shake Oroville dam?

Which quake? Lone Pine?

Nah, too far away.

Yes, cdec reporting an elevation of 804', about 10 feet lower than the bottom of the spillway gates. Yet water is still flowing out of the gate structure and down the spillway.

How can that be?

Additionally, outflow is currently reported at 7,674 CFS versus an inflow of 1062 CFS.

Obviously, DWR is trying to draw the reservoir elevation down quickly. But why? Typically, at this time of year DWR is trying to retain as much water (= $$$$) as possible.

Last year, DWR Spokesperson liar Erin Mellon stated that 'the reservoir will be kept at full elevation all summer long for recreation and irrigation needs'. Immediately afterward, DWR started dropping the reservoir as fast as possible without using the main spillway.

The same scenario is unfolding this year. They are avoiding the use of the new main spillway. Why? Did the newly installed vibration sensors indicate a problem the only time it was used? Are there underlying conditions due to seepage through the hillside or settling of the gate structure?

What does the DWR's redacted information in the Needs Assessment have to do with these possible issues?

As a member of the public living in the floodplain below this thing, I have a right to know.

You do. Start facebook groups and other apps to get people calling the news. You guys need to make some noise. Hey something is wrong and you guys are hush. I know it wont be easy but that is your only chance at maybe getting real answers is enough public interest. especially with that above you it is your right to know if it is in a failure mode.

800.19 DROPPING LIKE A ROCK! WATER IS PROB. DRAINING OUT OF THE EARTHEN DAMMED DAM ITSELF..AND THEY WANNA KNOW HOW MUCH? DANGER TIMES!

Yeah, under 800 now. Still large releases.

Reservoir elevation nearly 14 feet BELOW the bottom of the spillway gates...yet water still leaking down the spillway. Wet gravel on the left, outside of the spillway wall. Why is it wet?

Reservoir seepage under/around the spillway structure is the only viable explanation. It hasn't rained in weeks.

because Its failing. Which side is left to you.. .from behind the spillway... or in front of it...so I can look better. :personal green t:

Also can you see where you live.. the dam from the front.. I would like to see what it looks like.. especially the side that abuts to the spillway...

798.41

DROPPIN THE SHIT OUT OF IT...BACK DOWN TO 795 TO SEE HOW MUCH COMES OUT I GUESS...THAT IS THE TRUE BOTTOM OF THE GATES..RIGHT?

1.79 FEET IN 42.75 HRS?

How fast should it drop when its being released for crops etc.

When I mentioned 'left', I was referring to the view from the upper camera. There are areas of the gravel surfacing to the left of the spillway wall that appear to be wet (darker).

I cannot see the dam from my home due to trees and other structures. If I drive about a mile to the north, the view opens up and I can see the very crest of the dam although it is about 10 miles away.

It is difficult to see details unless very close to the dam, due to the hills between the dam and the valley. The river channel below the dam makes a 90 degree turn between the base of the dam and the bottom of the spillway. The hill that forms that channel blocks much of the view.

NOT SURE..BUT, NOW IT IS 797.36

TOP OF THE HOUR...SO...IT LOOKS LIKE RIGHT AT A FOOT A DAY.

As I recall, normal releases this time of year would be about 3,500 CFS total. That is just about what is currently being shown as the river release.

However, the release from the reservoir is currently showing nearly 9,000 CFS. That number really does not make sense if the river release is only about 3,500.

Remember that the Oroville Dam is part of a complex that includes two much smaller reservoirs downstream, the Thermalito Forebay and the Thermalito Afterbay.

Downstream from the dam and the spillway, there is the Diversion Dam. That dam directs the main dam outflow through the main river channel past downtown Oroville and also into the Diversion Canal, which feeds the Thermalito Forebay and then the Thermalito Afterbay. There is an outlet in the afterbay that sends water into the river channel south of Oroville.

If total river releases are only 3,500 CFS (river channel + afterbay outlet), where is the rest of the water going?

Some water is pumped from the afterbay for agriculture to the west, but that is 99% rice fields that should already be well-flooded by now. It just doesn't add up.

979.30...SO IT DROPPED 1.11 IN 27 HRS!

Reservoir discharges are all through hydro plant. Looks like they operate a few more turbines from noon - midnight than midnight - noon. Power peaking to maximize electricity sales, I suppose.

Night: hydro uses ~5,500 cfs
Afternoon: hydro uses ~8,500 cfs

Looks like they also just about shut down hydro every Sunday, dropping to barely 2,000 cfs of inflow.

If they average 6,000 cfs over the week for hydro, then that's just under 520 million cf/day or 12k acre ft/day. That would be (roughly) around a foot/day at current levels. So, nothing too unusual.

Oroville is low, but isn't *that* low considering the rest of the reservoirs and the dry season.

Water porting through the spillway? I got nothing for ya, there. The drainage system is state-of-the-art and there's big, rubber water stops sealing every slab gap on the spillway. Absolutely NO water can possibly collect below the slabs or infiltrate up past the waterstops. It's probably the DWR just trolling everyone.

There's obviously some sort of time-space antimatter wormhole materializing water deep inside Ol' Crackey. That just happens sometimes on California infrastructure projects. A mystery of nature - there's just no explaining it.

Strange glow over Shasta?

What do you mean?
