Emergency: California’s Oroville Dam Spillway Near Failure, Evacuations Ordered

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.

I agree.
While the inflow vs. outflow are interesting to know,
the important number is the lake level.
-
02/20/2017–6:00pm Level: 849.38 Outflow: 60447 Inflow: 88814
-
They are maintaining the goal of 50 feet below the emergency spillway.

Another item of interest. Since this morning the 24 hour rainfall measurements in the Oroville basin are starting now to look like the production of 7 to 10.

Last 24 hours the Gauges are as follows:
Brush Creek 3.47
Strawberry Valley 4.79
Four Trees 4.79
Bucks Creek 2.92
Bucks Lake 5.39
La Porte 5.59
Quincy 3.80
Grizzly Ridge 3.89

These figures don’t include rainfall prior to 7:00 last night as they are 24 hour totals not storm totals.

Water level in the photo had to be during the 1st flood condition (either just before or just after the Emergency Spillway overtopping). Water elevation in the photo is above 880ft, closer to 890+ feet.

>>re: bubbles & youtube link.<<

Hi Ray, FYI- The youtube video (posted link reference) is a poor resolution version. It is worthless (for detail analysis). Either their source reference or their youtube upload resolution settings were set so the original footage fidelity was lost.

There is a much higher resolution video feed (in hi-def) that is a significant difference. To do forensics on the shower of bubbles emanating from the ground surface it is optimal with a full 27" true color GPU based display, 2560 x 1440 resolution & 32-Bit true Color (each pixel is stored in 4 bytes: ARGB8888 standard). The water level was about 4 feet deep (900ft at ES height at time of imaging - 896ft elevation at the road/soil level). You can see the dirt road under the semi-occluded water. You can see the origin of the bubble froth burst start in a smaller diameter condition at the soil surface depth. As the bubble froth cluster moves upward to the surface, it spreads like a cone. When it breaks the surface it spreads into a wide dispersal pattern.

These two images show the resolution difference between what you posted and a higher def resolution source. I don't know how this looks on non-high end display systems, but the difference is very stark with a good GPU & display system.

Here's the Low Resolution (from youtube link in post):

Here's a High Resolution (from hi-def source):

This image shows soil surface & road in front of the Emergency Spillway.

? bad links in first two images ?

[EarthResearcher333]

Perhaps this is a good test.
On your display, do you see any clarity difference between the upper and next pic down (fox news room views)?

[Ray76]

I disagree.

Around the 28 second mark a similar sun glint can be seen at the gates.

The glint at the weir appears simultaneously with the camera’s aperture opening up.

The “bubbles” at the beginning of the video are a shorter snip of extended view at 8:58. Note the angle of the “bubbles”, lower left to upper right. At 9:26 note the shadows cast by the trucks, the same diagonal.

The only time “bubbles” appear is when facing toward the sun, never with the camera’s back to the sun. You can see the orb of the sun in the reflection.

By the way when I view the youtube it is not blurry as in the first picture but focused as in the second.

In the first image I see a girl and a guy (fuzzy)
In the second image I see a girl and a guy (more clearly)

[Repeal The 17th]

I have seen all the posts and videos of the alleged “bubbles:.
I never thought they were bubbles, either reflections or debris.

[EarthResearcher333]

So you aren’t able to see the cluster (froth) emerge from the soil, flow upward, and then spread in a wash at the surface?

The helicopter camera operator, also saw this dynamic action. Except his view was not at a 1 sec step rate or even 2 sec step rate that youtubes are uploaded to.

It’s ok to agree to disagree.

[Ray76]

If you know of a better video I would be happy to take a look at it.

[EarthResearcher333]

I had to dig through the archives of all references & sources. It’s up to 2.9Meg (without all of the reference photographs).

Here is a hi-def youtube link that is much better:
https://www.youtube.com/watch?v=EqEU2X6yBPk&feature=youtu.be

HOWEVER, to see the action your system must be able to step frames in fractions of a second. To do this, you stop the play, then move the red sliding dot precisely & see the dot shift by a few pixels (horizontally). You should be able to get at least 4 individual steps (frames) before the time stamp advances to the next second. If your system only advances a full 1 second or worse 2 seconds, you lose the important dynamic action. It also helps to see this on a 27” hi-res display (as the bubble formation foam is more faint emerging and flowing up in the water).

[Repeal The 17th]

Bubbles are round (spherical) not squarish.

[Ray76]

> So you aren’t able to see the cluster (froth) emerge from the soil, flow upward, and then spread in a wash at the surface?

I see no wash at the surface. I see sunlight reflecting off some wind ripples in the water. I see no ripples emanating from the “bubbles”, only undisturbed wind ripples.

[Ray76]

You might want to check that link, it’s the same as in #1672

[EarthResearcher333]

I must have grabbed another reference youtube link.
You are correct that the “good” youtube links are the higher resolution (same with different extensions). (this was a good exercise anyway on the mistaken link as some are unaware of re-postings and lesser quality versions).

I’ll put up a series of pics in a bit so you can see what I’m referring to.

>>Bubbles Discussion: Precision stepping of select images of surfacing Bubbles near Emergency Spillway<<

Hi Ray76, ..note: Apologies for larger size pics. Zoom necessary. Here are image sequences that show this phenomenon. Keep in mind that the "seconds" in the lower image can be steps of approx 250milliseconds. This means there are multiple images between the second marks. IT takes great care & the right setup & tricks on your system to access these frames (fullscreen mode, precision control of advance bar - few pixels at a time, etc).

For brevity, I've captured relevant sequences. Otherwise it is too much information to post (too many images). Hopefully these sets of sequences will illuminate the discussion. (i.e. can reflections cause these dynamic results, is this debris, are these waves, etc).

I have an advantage on my high end workstation as I can see more detail than what I can post. So I don't mind if conclusions do not concur. (I do image analysis of deep space infrared telescope pics with this system).

To help on the lower resolution viewing, I shifted the color parameters on the last image to help make it easier to see. In this color shift, ANY reflection source would stand out. Thus the reconciliation with the shape to a suggested reflection source would be the key to answering (for the "reflection" thesis).

Another interesting point about "reflection" or "debris" is that it has to fit within the "comes then goes" in addition to the "faint to bright" dynamics.

I'm including the rest of the cc's so they can give feedback on how these images look on their systems - & to keep them up to date past "bubbles" discussion/post many many threads ago.

[EarthResearcher333]

Add’l info to discussion: “Bubbles” has been a loosely applied term here. The nature of these events are more of a “gas venting” through a sediment/aggregate material. This creates a much different formation condition than a singular type of a large spherical air cavity (or a simple large “bubble”). The air will froth in a complex gas release.

Another important note: Keep in mind the scale. The Emergency Spillway is very large. To determine the radius of a surfacing/surfaced “air froth”, it should be compared to the large size Emergency Spillway Weir to the right (near 53 feet from water edge face to backside concrete extending “foot”).

Nice one.
