Three-Phase posted:Is this gonna be one of those things where once the water starts flowing down outside the main spillway it will just dig away at the earth, causing more water to flow causing more erosion until there's an extremely severe flood? Right now it's going over the emergency spillway, which is located further down the reservoir than the actual dam. The emergency spillway is what is going to fail, doesn't look like the actual dam is at risk yet

Dapper_Swindler posted:so whats a spillway? is the dam going to break. How hosed are the people? It's not part of the dam proper, it's part of the reservoir water level management. The emergency/auxiliary spillway is basically a last resort failsafe to let water out of reaervoir without overtopping the actual dam

Serak posted: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.

Random Stranger posted:I think the spillway going and releasing the top thirty feet of the reservoir counts as a dam failure in general conversation. When people say "tallest dam in the US about to be breached" that kinda gives the impression of the big wall, not the small flood control wall

qkkl posted:So hundreds of thousands of people were evacuated. Does this mean that over a hundred thousand people would have died if they didn't evacuate and the dam broke? Seems like dams would be an ideal target for a terrorist attack if that were the case. After 9/11 they massively restricted access to a lot of dams. You used to be able to see a lot of coll stuff in the Hoover Dam and it's all off limits now. The Kensico dam in NYC used to have a road over the top and it was closed for 8 years and then restricted to bicycle and foot traffic only.

Monos Bullet posted:They should be evacuating people to the dam and hand out straws when they get there. If the 200k people evacuated get at least the recommended 1 gallon a day drank, then the water will recede in no time. What happens when they need to pee.
