And here's the emergency overflow, basically just the side of that mountain there

As a human being, I feel for the people suffering from this failure of bureaucracy and investment in infrastructure

As a civil engineer, I enjoy watching poo poo getting wrecked on a grand scale.

he's not wrong about the evacuations tho



Oh Jeez - the catchment for Oroville Dam is not small.
It might manage to mitigate the current overflow without the auxiliary spillway failing, but there's still a hell of a lot of water on it's way in over the next week.

I think that's a matter of semantics at that point.

If the emergency spillway fails then the lake will just drain out that entire hillside and the dam itself will effectively be useless as the water will have a different outlet. It kinda doesn't matter if technically the portion labelled "Dam" hasn't breached at that point.

If the spillway breaches, you only lose the top 30ft ( think that's the number they mentioned) of water, which - don't get me wrong - is still a wall of water coming downstream, but the dam will still hold the majority.

It's the difference between 30 feet and 900.

True, but the top 30 ft would be over a MUCH bigger surface area than even the 30 below it, so volume-wise it's not easy to judge

thank god we have so many experts on the geological composition of the landscape in and around this particular dam who are also psychics that can predict exactly what will happen

Thank god that the interaction of water, soil and concrete is an arcane mystery about which we cannot even speculate & only The Lord himself knows the truth!

Or maybe we're all just listening to the experts talk.

kind of lazy and irresponsible for media to report this as a dam failure when it is spillway

too bad media gets its news from Twitter now

It's really not - if the spillway fails, there's still gonna be enough water heading downstream to kill a whole lot of people if they don't evacuate.
If they start claiming that 'only' the spillway might fail but the dam will be OK , there are certain to be people who ignore the warning
