BREAKING: Fearing collapse of emergency spillway at Oroville Dam, Oroville evacuated

a reply to: Natas0114

No, this is how the state performs a cull. Im sorry if you loved the lost... they drowned.. alone and afraid....

But what about the weed?

a reply to: ExNihiloRed

It has failed.......

a reply to: Aeshma

Nothing you are saying makes any sense.

reading the thread may help.

The lake level has been lowered. There is no more water going over the emergency spill way.. That spill way is not the Main spill way that broke about half way down.. the part that broke is just a ramp, it does nothing to hold water..

people have been evacuated..

130,000 evacuated.

Just got in to see this.

They are trying to drain some water.

Bummer.

trying?

They are draining 100,000 cubic feet per second.

they will be able to see the emergency spill way now as it is no longer under water.

If that part was going to break it probably would have already happened.

A huge amount of water pressure has been taken off the structure.

it's looking good, but we will know much more tomorrow.

Yeah of course, to try and relieve pressure and erosion.

Slow it down to work on it.

Storms are coming in on the weekend too.

the erosion of the emergency spill way is not happening anymore as the water is not overflowing over there anymore..
you said trying to drain water.. You didn't say anything about erosion or pressure.

the ramp structure will get a bit more damaged but that's not the main concern..

Storms are coming thursday 3.5 days away

Just something to think about regarding the scale of this, it's releasing about 100,000 cubic feet of water per second. A cubic foot of water on average weighs 62.3 pounds.

6,200,000 pounds of water per second..

Pretty crazy right?

but that is not even the max it can handle.

Reports have an estimated 188,000 people evacuated from areas below the dam.

The plan to dump rocks and dirt into the area below the auxiliary/emergency overflow spillway has not yet been implemented, but has not yet been officially delayed.

Officials are not certain if that plan would have been (or, in light of additional storms due later in the week, will be) effective at stopping or at least slowing the erosion than was caused at the base of the emergency spillway when it was topped.

The immediate emergency has past and they have a few days to evaluate the situation and act to remedy the damage as best they can.

We are not yet out of the woods, but a lot depends on what those coming storms bring.

OY!

They said Fri and Sat for the storms. lol.

Fine, hope they start tomorrow.

So no threat? Is that what you're trying to say?

The "ramp" is made of dirt.

So is the DAM!

Once water starts eating through it with that much pressure behind it, it's done.

California. Run to the Hills!

a reply to: burgerbuddy

NO..

The Dam is just sitting there nothing happening with that..

the Spillway is made of concrete..

Quit hoping for death. The pressure is lowering every second and the max pressure it held is an extra foot or two of water at this point. That's a HUGE reduction in pressure along the 1700 foot wall (emergency spill way also made of concrete)


the threat is lowering we will know tomorrow as they assess the damage now that they can see it as no more water is overflowing the emergency spill way.

quit being an ass

a reply to: burgerbuddy

On top of the forecast storms there is also the problem with the meltwater from the snowpack that will also be draining into the lake.

Kinda like the "perfect storm" when all the elements come together at the same time.

Fingers crossed, stay safe

a reply to: corblimeyguvnor

the water draining from the lake is MUCH greater than the rain and melt water coming in the lake levels are already down feet..

they are draining 6.2 million pounds of water per second...

The rain coming in is only dangerous for people down stream where all this water is draining to. the Dam itself isn't going to break the pressure on it is already greatly reduced.

Hope you're right

you don't have to hope, everything I said is a fact..

were you watching the press confrences or paying attention to the water levels?

Do you know which part of the spillways are damaged or anything that's going on?

The part that was dangerous, no longer has 1.5 feet of water rushing over the top.. later it was down to 2 inches over the top, and now it's another foot lower than that..

the combined effect of rain and other water many days from now is like 4 inches, not feet..

the real damage on the spill way is only to a "water slide" and really has nothing to do with the structure that holds the water.

a reply to: Reverbs

A little less attitude would be nice, to that end i will just say I know nothing about water levels, press conferences or damage to the spillway [sarc]

there are two spillways.

one is a 1700 foot wall type structure..
One is a concrete channel.

there is no longer water coming over that strip in the secondary or emergency spill way
That's the danger zone.




the damage is mainly here:



but that being damaged isn't make or break..

it's that secondary spill way that needs to stay intact.

and it had it's structure tested at way higher pressures than it's at now.


The actual Dam is off to the right, not shown in either picture.

Man if only they followed immigration laws maybe the army corps of engineers could help....
