How did a giant, gaping hole tear through the massive Oroville Dams main concrete spillway last week, setting in motion the chain of events that could have led to one of Americas 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, ...

Don ho died from tiny bubbles in his brain
1. The counties downstream hold a majority Republican population.
2. (More importantly) Federal and State funds were shoveled into the coffers of Granite Construction, heavy contributors to Democratic candidates in California, to construct a completely useless, albeit massively expensive, spillway project at Folsom Dam. The spillway repair at Oroville was just too diminimus to waste Granite's time.
But, if you just try to prove this unwarranted accusation, expect to find yourself as a bunkmate with Jimmy Hoffa.
If only Cali would have given the General Contractors EBT cards, they could have done the job in a flash.
This situation will allow us to smuggle tax free cigarettes into Sacto!
You made me look...
as a mechanical engineer into fluid dynamics, cavitation was likely present, it always is. But beyond cavitation once you get a hole started you’ve got turbulent circulation going which will pound the crap out of everything. So maintenance was the problem, not dealing with the minor repairs that cavitation may have started.
looked like a crappy foundation job from the pics i saw.
The kickback from 200 million is a lot better than the kickback from half a million!
EXPANSION JOINTS HAVE TO BE CAULKED.
Everything else is misdirection.
Making repairs on a dam may get you a couple of inches of print in the local paper with 20 thousand readers at best.
Spending billions on a high speed train from nowhere to nowhere will get you national press over and over again.
Its a simple choice when you are an ambitious politician with delusions of grandeur.
One of the contributing factors that I saw mentioned early on is growth of trees and brush in the emergency spillway. As the water poured through, they were uprooted creating holes which caused serious erosion. Without the growth, the water would have flowed more smoothly over the surface, as designed.
Lack of maintenance and inadequate inspections are pretty likely causes in this layman’s view.
Cavitation is just a guess from someone NOT at the site.
It’s obviously the fault of the delta smelt burrowing in all the weak spots.

Thanks for the evidence Karl, you got 'em cold.
“one of Americas deadliest dam failures”
When did that happen?
When did that happen?
That is the Author's misdirection.
This article is the start of an MSM narrative of a "scientific principle" as cause of failure rather than criminally negligent maintenance and inspection failure on the part of California Public Employees and Politicians.

Oh, I know. The first couple of sentences in the article is enough totally discount any further verbiage.
