Oroville Dam: What made the spillway collapse? (California)
San Jose Mercury News and Propaganda ^ | February 17, 2017 | Paul Rogers, Coverup Department

How did a giant, gaping hole tear through the massive Oroville Dam’s main concrete spillway last week, setting in motion the chain of events that could have led to one of America’s deadliest dam failures?

Dam experts around the country are focusing on a leading suspect: Tiny bubbles.

The prospect is simple, yet terrifying and has been the culprit in a number of near disasters at dams across the globe since engineers discovered it about 50 years ago. In a process called “cavitation,” ...

The Smirkury Snooze completely misses the fact that the cavitation problem was known in the early sixties and proved engineering fixes were successfully completed and proved in several similar dams before 1984.

Why then was Moonbeam Brown's DemoRat run California unwilling to spend one dime in 35 years, to prevent the absolute disaster of the near collapse of the Oroville Dam?

Dirt moves around over the years as the ground is run through repeated water saturated and dehydrated cycles occur.

Plus gravity rulz. It's not just a good idea, It's The LAW!

Or maybe Don Ho's -- "Tiny bubbles, etc."

No way that media source will ever tell the truth about it. Jerry Brown and the rest of the gov workers steal money from road work, water rate payers and for all infrastructures.

The left wants its 250k pensions and all infrastructures destroyed. Less cars on the road and the goal only 2 class of people...poor and them.

Did you know Brown gets money from a oil company that was taken over by a coup in another country?

Easy. Politicians. It is way more sexy for a progressive politician to name a new foot bridge after themselves than to repair existing infrastructure. And besides. California was never going to get precipitation due to global warming.

Incompetence. A state that was and is more focused on PC silliness than on doing its job.

"But despite the lessons from Glen Canyon, the Oroville Dam spillway apparently did not have aerators. "

There are some sort of water sprays on the sides of the spillway that must have been installed for this effect. Apparently not effective.

Um, my guess: Entropy and 45 years of zero maintenance.

I hated Science as our savior once I found out about Entropy.

I doubt that cavitation had anything to do with this washout collapse. problems ? grossly neglecting maintenance repairs and lax inspections more likely.

Because the dems are so narrow-minded in their thinking that spending an actual half a million in repairs to save a potential 200 million in repairs is a concept they are unable to process.

It was a near collapse last week. This week all bets are off. I rode around the sacto river levees today and there are many places where they are leaking. The Yolo bypass is a huge lake with rapids.

Wish I had bought that boat I was considering last fall!

Caulk joint probably not maintained and any water-stop was unprotected. We know for certain that scrub tree growth had taken over the side of the emergency spillway run-off area.

Yes, but hey still had cavitation and should have re-engineered the fix for it, which would have made the spillway function properly and remain undamaged.
