California's Lake Oroville Main Spillway Severely Damaged/Eroded. Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed

Shasta Lake is so low you can kayak through an old historic train tunnel..


Shasta is always releasing water to keep the salinity barrier in the delta correct. The leaders in California do not believe the Earth can heal herself.


Shasta lake will dry up someday soon.

REALLY? You people still talking about the spillway that never busted?

My take on events is that the spill way is still in trouble. Since the repairs, there has been an uptick in ground movement. The dam can come down with water or without. It wont take a 6m eq to knock the thing down, a whole lot of little quakes can do the same damage. That whole dam is a recipe for liquefaction. At some point, the red clay dirt will crumble, sooner more so than later.

Notice all the road repairs being done in the area? Same thing.

631.87 NEW LOW. ALSO, IMCOMPLETE DATA FROM A FEW HRS BACK. I SUSPECT SOME SORT OF TURBINE TRIP. UH. DUE TO LOW WATUH..

632.06 ANOTHUH NEW LOW. UH.

.19 FEET IN LAST 24 HRS. CALL IT ONE-FIFTH OF A FOOT? UH.

Yes, the 'impervious core' of the dam.

It is comprised of red clay soil and crushed rock from the dredger tailings that are ubiquitous around the Oroville area.

When red clay dries, it shrinks and cracks. When it gets wet, it swells and turns into gumbo. It is known as an 'expansive soil' and not suitable for building on, because it moves around depending on changes in moisture.

Our local school district was building a new school back around 2005. The engineers demanded the red clay soil under the building foundations be removed and non-expansive soil to be brought in to replace it. This elevated the cost and extended the timeline for building the school. But they had their reasons. Red clay is not a suitable foundation soil, BECAUSE IT MOVES.

Yet, some fools in the 1960s built the Nation's tallest dam using red clay soil.

thank you for a most interesting reply.

632.02 5 HRS STRAIGHT..MAKING A STAND?! UH

631.73 DOWN AGAIN..THE DRAMA. UH.

If it wasn't for the drama, we wouldn't be here.

Right?

I wanted to get this thread back into my active threads with something different for you Crunch62.



Giggles to self and hits post.

U KNOW IT...HEY, WHAT DO YOU THINK BOUT MUH THEORY OF INFLOW 'DEBRIS' DISPLACING ACTUAL WATER THAT 'WAS' FACTORED
INTO THE LAKE ACRE FEET 'VOLUME'?

...AND THEN..THEY DROPPED IT 3 FEET OUT OF NO WHERE...THEY WERE ALSO PLAYING WITH THOSE BIG NEG. INFLOW NUMBUHS...WEIRD. REMEMBER, IT WAS LIKE NEG. 94K...! STUFF LIKE THAT. UH.

I THINK THEY FINALLY DID AN INVENTORY OF THE DAM/LAKE AFTER
60-70 YEARS AND HAD TO ADMIT THAT DEBRIS FLOWED INTO IT ADDED UP TO A DECENT ANOUNT. CAPS

I think you are spot on. Silt has been accumulating in the reservoir since it was originally filled. Accelerating especially after years with lots of fires. Lots of mud and debris washing down into the reservoir when the rains come and the watershed is bare of vegetation.

Remember rain?

For the last two summers in the AZ Sonoran desert it was 100% Nonsoon. This year we got a really robust Monsoon - so much so it cleared AZ of its highest drought status over a couple, maybe three weeks time, but it came with a price for some!
