The California Department of Water Resources issued a sudden evacuation order shortly before 5 p.m. Sunday for residents near the Oroville Dam in northern California, warning that the dam’s emergency spillway would fail in the next 60 minutes.

The Oroville Dam is the highest in the nation.

!!!!!!!!!!!!!

(Just in case anyone wondered if the coverup extended to FERC...)

Apparently FERC has an on-site person to facilitate FERC/DWR official communications through the online database. One possibility to this situation is if someone (on-site?) was talked into deleting the files (or removing them from any database access). You would expect that any action as important as deletion of information would need to be authorized at high levels.

I trust the feds as far as I can throw them.

BTW, the Federal Energy Regulatory Commission (FERC) is unconstitutional because the Constitution gives the feds no authority to regulate energy per se. The Constitution only gives the feds power to regulate hindrances to commerce between states.

The FERC is among the 80% unconstitutional portion of the feds. If the creation and existence of the bureaucracy is illegal and corrupt, the output of the bureaucracy will be illegal and corrupt.

UPDATE: FERC documents are locatable on the database IF you know what date window to look in using the P-2100 000 docket & subdocket codes.

FERC did a sly trick in preventing the finding of specific files using the "search tool". So far, I've identified 4 documents that have been disabled from the this search mode. 3 of the files deal with the Anchor tendons. 1 file deals with the "void" repair communication.

Correcting "conspiracy theories" re: scientific experiments, radiation counting, etc. under Oroville Dam at the Hyatt Power plant

Under Oroville's rock facilities near the Hyatt Power plant, an experiment was set up that was in conjunction with a worldwide scientific effort to answer a feasibility question on a much larger scale detector. The end goal is seeking new answers on the elusive neutrino particle. This is an international collaboration with other facilities performing the same type of testing. Collectively, the data may justify the testing method and thus trigger building a large scale detector. Oroville was one of the sites that is participating in the study - called "The Majorana Zero Neutrino Double-Beta Decay Experiment"

These units are bulky in requiring a constant supply of liquid nitrogen. The experiment needs to collect data continuously for several years to characterize the behavior of this instrument in a "test" setting underground (noted as "realistic conditions"). The rock overburden is useful in filtering natural external radiation such as from space. The goal is to answer questions in particle physics theories regarding the neutrino particle. The Oroville setup is one part of a collection of experiments to determine the viability of a massive large detector with the crystal size(s) in tonnage. They expect 1 count (capture) in an equivalent 1 ton of detector mass, yielding the unique impulse voltage believed associated to this form of a neutrino particle (2039 KeV). A large slab of lead helps shield the experiment, but at the same time, the lead has a background radiation emission profile (see image).

So, Yes there were experiments to measure radiation, but this was all natural background radiation, with the intent to shield the sensors as much as possible using the overburden rock of the dam abutment. The experiments were looking for very faint interactions of a special type of particle capture that is called the neutrinoless double-beta decay. How this experiment gets turned into a conspiracy theory of nuclear fission devices (that go boom), I do not understand. Moving this equipment out of a near flooding state in the Hyatt power plant would have been prudent & thus the need for a number of vehicles to transport the array of nitrogen tanks, detector arrays, and supporting equipment.

Experiment Sensors: High Purity Germanium HPGe Crystal detectors are a vacuum and cryogenic environment with Cylinders of pure crystal that react with a small voltage spike from absorption of natural background radioactive particles or rays. Amplifiers & filters detect voltage spikes (x axis), Counts of spikes = y axis).

https://en.wikipedia.org/wiki/MAJORANA

The MAJORANA project (styled Majorana) is an international effort to search for neutrinoless double-beta (0νββ) decay in 76Ge. The project builds upon the work of previous experiments, notably those performed by the Heidelberg–Moscow[1] and IGEX[2] collaborations, which used high-purity germanium (HPGe) detectors, to study neutrinoless double-beta decay.

The first stage of the project is the Majorana Demonstrator, designed to demonstrate the technique and evaluate a ton-scale experiment.

Cryostats housing up to 40 kg of natural and enriched germanium detectors are being deployed in low-background vacuum cryostats, underground at the Sanford Underground Laboratory in Lead, South Dakota. Following the Demonstrator, the collaboration intends to merge with the GERDA collaboration to build a much larger experiment.

The goal of the project is to search for 0νββ decay in 76Ge using HPGe detectors. Observation of 0νββ would establish that the neutrino is a Majorana particle and demonstrate violation of lepton number conservation, validating the seesaw mechanism as the explanation for the neutrino mass scale. It would also place constraints on the absolute neutrino mass.

The principal goal of the Majorana Demonstrator is to demonstrate the feasibility of achieving the background required in a ton-scale experiment. This corresponds to 4 counts/tonne/yr in a 4 keV window around the 0νββ Q value of 2039 keV, which scales to 1 count/ton/yr in a ton scale experiment. The experiment will use a mixture of detectors made with natural germanium and enriched germanium, allowing it to confirm or refute the controversial claim for 0νββ observation in 76Ge by Klapdor-Kleingrothaus et al.[3] If low enough electronic noise is achieved the Demonstrator may also make a search for WIMPs and axions.

Nice article here about another dam. Lake Isabella
http://www.bakersfield.com/news/isabella-lake-brimming-with-water-highlighting-dam-risks/article_4ba79919-0298-5740-a7f0-1180ad369147.html

This is the dam on Lake Isabella collecting the Kern River flow (Mt Whitney etc) coming south out of the Sierras. It protects Bakersfield. It is the highest it has been since ‘83 and right at the 66% capacity that it is restricted to as one of the most dangerous dams in the nation.

Seismic issues could put 5 to 20 feet of water in Bakersfield but the dam is also internally plagued with leakage issues that could get worse at any time — hence it is restricted to 66% capacity. When I went by the Kern River a few weeks ago, it was at 400% of normal May flow from snow melt.

It sounds like vital infrastructure maintenance and repair is not California’s strong point. But the pensions, unfunded as they may be, are awesome.

Yes. After I made the post I reflected that I should have written “Informative article...” rather than “Nice article...”

The human and American capacity to meet challenges is amazing if it is applied. I will agree that it is not infinite and reason must be allowed to temper our challenges we take on.

The understanding that CA was going to populate beyond its seemingly natural limits was reached over fifty years ago. They gave up and looked to disaster to limit or rescind growth rather than rolling up their sleeves and taking on the challenge. The state of California was a vast engine in our nation’s defense in WWII. The ability out there is still there but it is so clouded it cannot, as a whole, perceive a task worth doing.

We have Jim creating this site. We have hundreds of things wonderful still coming from our countrymen of that state. However, what comes from the local current culture, the vast swath of people herded into Groups by the left is vile and poisonous.

A question for the construction, concrete, type on the board.

Have any of y’all heard of a concrete batch plant being enclosed and insulated?

KC Burke may have heard of Geiger Concrete here in Kansas City and it sure looks like they are building a batch plant that has insulated metal siding.

I guess I can see enclosing a plant to help cut down on nuisance dusts but insulating same?

I wwll see if I can get a pic or two thus weekend.

Thanks for allowing me a slight diversion.

Sometimes this is done for temperature control both in cold and hot weather. The old methods used to be to add ice as a pound for pound substitute for water or to have the water slightly heated. Now they sometimes heat the aggregate or water it to cool it. All designed to have the mix at prime shape when batched.

When the GM10 plant went in where the old Fairfax plant was, one of the ready-mix outfits (perhaps Fordyce) put in a nitrogen injection equipped batch plant. If it is a permanent plant it would not surprise me at all for winter operations.

Thanks I was wondering about temp control of the batches.

It kind of amazing the many different types of concrete that are available these days.

Nice video.

I know that some of us called it Moonbeam canyon, in honor of the esteemed governor of California, but perhaps Croyle canyon is a better name. Moonbeam doesn’t deserve the recognition, even if it’s bad recognition.

The ES reinforcement is good, as far as it goes, but if the ES is used the hillside erosion will end up in the river and cause problems. There doesn’t seem to be any plan to protect the powerhouse or to armor No Name Gulch.

Yeah, it seems to me that the emergency spillway could be a much better design. A true hardened river-bed type of path with a guided flow direction to minimize erosion and protect the river from debris buildup should it be needed again.

DWR accidentally publicly releases CEII BOC memorandum report - Deleted quickly, but Google Cache captured a copy - Report verifies 15 inch slab thinning in upper spillway

DWR placed a document on their website that was a new version (work in progress) of an April 11, 2017 Memorandum No. 4. The document notes that it was "Prepared by the Department of Water Resources". This document was quickly removed off of DWR's website.

However, the unredacted document reveals information that DWR was refusing to answer questions on (i.e. how thin were spots). Upper Main Spillway Core drilling verified a minimal 15 inch slab thickness (Core sample 12). DWR had stated that they had measured depths of up to 4 feet in thickness, yet they refused to answer on any "thin" areas. This report proves the data from their own coring. Ground Penetrating Radar data provided the locations of interest to perform the coring & analysis.

Another key point is that core data reveals the weathered rock seam depth goes to 45 feet in the erosion scour hole area; plus the scour area is a "seam structure". They also discovered that water would disappear at deeper depths in this seam. This infers a deep chasm, void, or crack in the hillside. The depth of water loss was at 109 feet.

Of interest in this report is the types of materials that coring discovered under the slabs. The material ranged from highly weathered rock, to angular to rounded cobbles that included an aggregate fine mix. This would dovetail with the pre emplacement of grade material before the slabs were poured in the original postcard construction photograph. What is not known is if this material was "washed" to these locations, or if they were "trapped" in a pristine state from the original construction. Either way, the fact that they are present under the slabs reveals that his is likely a pre-construction emplacement (unless "washing" of the side basin area of the spillway was mobilizing materials into and under the slabs).

This information solidifies key findings in preliminary reports such as Professor Robert Bea's analysis.

DWR cannot deny the "thin" slab construction finding from their own coring information.

DWR publicly releases a BOC memorandum report full of details - here is one page with key points of interest. Document was Cached by Google. DWR deleted access to the file/link soon after discovering the public access to the link.
