CA - ‘Uncharted territory’ as Lake Oroville rises toward damaged dam

[CARIIS]

Seeing on the news, (fox) that now some are complaining about being evacuated, damned if you do damned if you don't. jmo

Its like that in hurricanes too! Far out of the woods so maybe they should hold off on *****ing a dash until more info is in this AM.

The media did not help with break imminent - gets more viewers - Cronkite would never have said that on the public airwaves!

He would have used all kinds of qualifiers experts fear that the structure may be compromised and out of an abundance of caution etc etc

Not screaming crawls on the screen - which wigged me out and I ain't even there !

He clearly stated last night that they can not throw rocks in the spillway because it has gotten to large. 40 feet deep.

They have some contingencies but they are limited cause they don't want to turn if off at this time.

The rocks are for the area under the emergency deal to shore it up

The great headline would be like emergency deal did not sustain the degree of erosion we were concerned about.

The horror headline could be erosion at the emergency one is far more severe than we anticpated

Watch the preparation before using helicopters to drop bags of rock into hole at Oroville Dam

California prepares for catastrophe: Battle to stop a collapse at America's tallest dam as 200,000 residents flee amid fears of a 100ft-deep flood that could stretch for 40 miles

All 23,000 of the California National Guard have been put on standby to assist the situation and recovery

Finally - live aerial shots of what is happening now the spillway is really violent near the bottom -- much crazier than yesterday

Heavy lift helicopters coming in

Quite a sight

Saw first close up of the base of the emergency thing also amazing

I did hear earlier that it is the first time the spillway has been used.

Too bad there isn't an overflow reservoir to save that water.

 

[CARIIS]

Do have say they have done an amazing job of getting all that stuff in "action" during darkness!

No idea what it means but the data page has not given a number on inflow in the last 7 hours

On October 17, 2005 three environmental groups filed a motion with the federal government urging federal officials to require that the dam’s emergency spillway be armored with concrete, rather than remain as an earthen spillway. Federal and state officials said it was unnecessary and concerns were overblown.[25][26]


Spillway cracking and inspections

The spillway cracked in 2013. A Senior Civil Engineer with the Department of Water Resources was interviwed by the Sacramento Bee and explained, “It’s common for spillways to develop a void because of the drainage systems under them” and “There were some patches needed and so we made repairs and everything checked out.”[27]

In July 2015, the state Division of Safety of Dams inspected the dam visually "from some distance."[28]

Does the spillway look shorter to you guys today compared to yesterday

trying to find still pic of yesterday and today

Well, this is what was supposed to happen!

It's a crying shame how we, as a nation, no longer maintain our vast infrastructure. Doing so makes sense, saves money and creates jobs.

It's amazing to observe this system, built in the late 60's, still working, still providing necessary water to millions of people. It's an engineering marvel, the kind of thing we used to be proud of back in the old days. Growing up, many of the smartest kids in high school went on to get college degrees in civil engineering. Today, they're lucky to find decent paying work.

Time to invest in research, innovation and infrastructure again.

Photo here of the damage in 2013, it appears to me that it is the same area that has given way now.

afternoon temperatures expected to be above freezing well above 4000 feet, we are going to see snow-meltwater continue to flow in.
