1 inch of rain @ 3,222 square miles = 17,842,176 gallons of water headed towards Lake Oroville

However, Thursday the weather forecast is calling for .5 inches. The day after, 1 inch. In the 10 day forecast.

It's an additional day with .5 and another day with 1. For a grand total of 3 inches. = 53,520,000 gallons over the next 10 days from the entire Lake Oroville drainage basin.

AND....

AND....

The night temps for the next 10 days are supposed to be 10 degrees above freezing. Daytime temps 50 to 65. So add more water as the snow melts to the 53 million gallons. The snow pack this year is the peak for 22 years.

Doom on.

it's draining 750,000 gallons per SECOND x 60 per minute x 60 per hour x 24 per day x 10 10 days

so with those numbers you are draining in the 10 days 648,000,000,000 gallons

take away your 53 million take away snow melt..

They had the drainage turned off to look at it multiple times and had it running super slow to try and save the structure with all the erosion.. Then they realized how bad it was and said ef it..

there is no doom here.

You make it sound like a good thing,massive flooded homes lost and crops and could be like Katrina.

Nothing is flooding.. The rivers downstream can hold a lot more water before they go into flood stage.
Or what did you think the spillways were for? Decoration?

the emergency spillway had a headcut coming towards it that if left unchecked could have gotten to the base of the 30 foot high emergency spillway and possibly eroded underneath.. If that had collapsed a 30 foot wall of water would be coming over the hill.. With an entire lake behind it..

That was the danger..

Now they have people standing there, because it's no longer an issue..

OK so build a home and live right under it.No way that thing is safe with all the water they are gonna run off.Sounds very familiar to Katrina disaster because they are not sure how to fix it all.

huh?

I already told you the water is going into the rivers which are not at flood capacity

and they do know what they are doing.


I do wish the news reporter would stop calling this a "fluid" situation..

CNN showed crops flooded all ready lol.It is the erosion that can collapse at anytime.If that never happens they will recover and be ok.

I'm not aware of any crops flooding.. Maybe you are confused.
probably mixing some other event, with this..

A flood warning that is in effect until about 8PM eastern time today, was only if the second 30 foot by 1700 foot wall somehow eroded and fell..
That did not take place..

Look up the flood levels of the rivers..

LA Times updated 12 minutes ago mentions no flooding.

You have no clue what you are talking about.

I've been watching this since the thread opened.

It is the erosion anyways dude.They will no longer be able to control the flow if certain erosion collaspes.So chill out.

www.mercurynews.com... This blog is showing some damage,not sure where it all is.

That is not true.

And I am the one trying to chill you out.

Look the original erosion was on the Primary spillway.. This is why they shut that spillway off letting the lake water rise.. OK?
Then when the water levels got super high, and they had to use emergency spillway.. that started erosion, that was moving up towards that emergency spillway.. OK

So then they turned on the first one much higher and the lake levels sunk by multiple feet.. THere is no further danger of erosion on the emergency spillway as there is no water over there..

Get it?

they are lowering the lake by 80 feet in the net three days.

There is no flooding from the lake water.

it was only them trying to save a water ramp that caused the real issue to the left.. The emergency spillway had never been used before. So it had some issues.. So they stopped using it.. The only thing that is eroding is a concrete ramp.. It has no bearing on holding back water. The water is doing what it's supposed to be doing.

This is a semi live picture.

Click on it to see it.




People are confusing TWO issues. One is in red one is in blue..
The red one is what made them stop draining water there. It's just a hole in a ramp. It's not a critical structure short term.
the blue arrows are pointing to the 30 foot wall that no longer has water coming over it. That was the spot of dangerous erosion and hence the evacuation and "imminent" failure possible.. but that was when 2 feet of water were going over the top, last night the water level was lowered so far the water was then not going over that..

So that structure will not fail, and the other one is non critical.. They will need to fix it at some point, and probably redesign the emergency spill way because it really shouldn't have eroded like that.

But to say AHHH Doom!! is irresponsible and incorrect.

I agree with you.....Certain parts hopefully do not have major erosion again.That is what I mean about possible major flooding and more rain may be in their forecast.

a reply to: Jobeycool

No lol.. There is no erosion taking place.
Again. the water causing the erosion is no longer flowing over the emergency spill way.

And when it rains the lake will be around 80 feet lower than it is now..

the news people are mixing the two spillways into one idea because they are just idiotic or want ratings.
They have misquoted people, gave bad numbers. Can't tell the difference between erosion of dirt, and a hole in a ramp..

The real danger has passed. Nothing is at risk of collapse. EXCEPT possibly the end of a water slide. It has no real function except that it keeps the water from ripping up trees or rocks or dirt.

this situation wouldn't have even been an issue if they had just continued to use the main spillway.
they were trying to save it because it's going to cost a LOT of money to rebuild it. But when they realized the danger on the wall to the left they just reopened it and said whatever we can build that back later..

recap
~there is no flooding from the lake
~the 30 x 1700 foot wall is not in danger of collapse (that's what the evacuations were for)
~the water slide is no longer eroding, but has a huge hole in it. (it's just a ramp)
~water levels have lowered a big amount, and will continue to lower 80 total feet before the next rains
~flash flood warning expire later today (those warnings were due to the 30 foot wall scare)
~the dangerous erosion was making a head cut near the 30 foot wall and was getting too close for comfort, if enough dirt had eroded and it met the wall and started digging under it the entire wall could have collapsed releasing the flash floods.. 30 foot wall of water.. That will not happen.
~reparations to the eroded areas are expected to start soon.

For some strange reason that live stream's footage is mirrored. So the perspective is reversed, left is right and vice versa.

How irresponsible for the Streamer, or the news cast to get that backwards. It confuses what is the issues that are being discussed with "x" to the left, or right.

Thanks Anyway

You ok.

I'm providing the real data for this thread.

You are acting very emotional and strange.

get it together.

a reply to: Reverbs

Thanks, Reverbs for wrangling this thread and keeping it within reality.

Now that the "eminent" part of the danger is reduced. What I would assume is most important news details are; How long will repairs take to shore up the emergency spillway(the 30 foot wall) and when do the evacuees get to return?

The disruption to lives, businesses, and traffic is massive.

But, but, you're ruining the breaking imminent armageddon disaster by telling us its 'under control'.

We want to be veeeery afraid.

(thanks for the effort, I agree with your assessment)

188,000 people and for now they are not allowed back.
But at the same time the Flash flood warning due to the danger to the wall has not been extended.

So if you saw the inspectors standing on the "spill way" the dirt in front of the wall..

They are not looking at the wall structure.. The part that would be devastating if it fell, they are looking at a head cut.. A hole in the ground. That is hard to jusge the scale of but lets guess and say it's 50 feet from the wall.

I'm just confused why it would be designed like that.

So they will fill that hole in the dirt with bags of rocks and sand. (that's the "repair")

the problem is the use of the term spillway, sometimes it means concrete ramp, sometimes it means the side of the hill, sometimes it means the wall..

The other spill way will not be able to be fixed until the lake level is much lower making the draining of the lake unneeded.. Who knows when they might get that oppurtunity, but there is a Third way to drain the lake.. That is through the power station of the dam.. it's only rated for 10,000 cubic feet per second, but once the lake is a lot lower and they turn that back on it may give them access to the main spillway, to plan a way to repair it..

I doubt that's an easy fix.

but as far as water levels in the lake, they are back below 100% capacity.. Which is great news, and expected to fall another 80 feet in the next 3 days.
