Blind Rasputin posted:Does that mean we are out of the woods and the spillway won't fail? No. It decreases the likelihood of failure in the immediate future, but there’s more rain coming and both spillways are busted. I think they can drain the lake a little through the powerhouse, though, so that’s good (at like 20% the ordinary maximum spillway rate).

From Wednesday:quote:The emergency spillway, which has never been used, is designed for the scenario of the “biggest flood that any overgenerous engineer could ever dream of coming through that system with a full reservoir,” said Lund of UC Davis. The flows would be unregulated, meaning the state wouldn’t have any control over how much water pours down the emergency spillway, Lund said. That engineer didn’t have a very good imagination.

Guy Goodbody posted:The alternative is to just not have an emergency spillway, so if the dam breaks the dam breaks and everyone dies You have to have an emergency spillway, but you don’t have to have one ‘subject to "catastrophic damage" when used as intended.’ In about thirty hours it went from “this is the first time water has ever trickled over” to “GET OUT WHILE YOU STILL CAN”. And it did this in far from worst‐case weather. An emergency spillway ought to have had the integrity to last days of sustained downpour.

The latent heat of a million acre‐feet of water is only three exajoules. That’s only like seven Tsar Bombas. We could evaporate the water and make it Nevada’s problem. Michael Bay, are you listening?

guidoanselmi posted:Hi thread, I've been working with FEMA and CA DWR on this the past week on assessing the situation. There's been a steady downgrading of potential rain predictions which, possibly in conjunction with repair work (I have no idea on that front beyond public news), have made authorities confident enough to lift the order. Keep up the good work.

The California hate in this topic is misplaced. There isn’t a single $2 k/ 1 bedroom apartment in the entire area that was evacuated. The median income in Oroville (right under the dam, pop. 16,260) is $36,581. That figure for Yuba City (larger city downstream, pop. 65,416) is $50,494. Check out the top employers, too: Oroville | Yuba City Real fart‐huffing Hollywood types.

It’s a good thing that the “let’s try the emergency spillway for the first time in the dam’s history” experiment didn’t occur when inflows were particularly high.

Duzzy Funlop posted:And during those 4 days, they never increased the throughput of the main spillway, keeping it below 40-50k cfs in order to minimize erosion. Yeah but the the emergency spillway blows and needed to be replaced wholesale anyway. Now there’s incontrovertible proof of that. The evacuation costs could have been avoided, though.

Ill Peripheral posted:And the very close call with the brutal water murder of thousands downstream. I remember when they called the evacuation, they thought the spillway was going to fail within an hour, which was nowhere near enough time. I want to know if there was any consideration of “this is one of the less dangerous times to uses the untested emergency spillway” or if it was all luck.

Javid posted:If a 1.8 did literally anything to that dam it would've collapsed long, long ago. Seismologists aren’t as smart as meteorologists. There are no small hurricanes. If you have something that’s kind of like a hurricane but puny, it’s called a “tropical storm”. Seismologists should have decided “it’s only an earthquake if it’s at least 5.0” and then stuck to it.
