Drano has met it's match

That would be cool to try to slide down through there right when just the first bit of water started to flow....certainly not when it was gushing.
It would take some balls, though.

I've been to see that at Lake Berryessa a few times, it's a trip. You can't get that close to it in a boat though. I've only seen it draining once though, usually when I've been there it's summer and the level is way too low.

Now the party bridge at Lake Berryessa, that's where the fun is at in the summer.

I'm still wondering why they don't just have normal spillways like every other dam in the world? It seems like buildings a giant "glory hole" intake would probably be more expensive than normal spillways. Perhaps its because small dams liek these are not continually monitored and therefore don't have people to operate the spillways in case of flood?

It drastically reduces the cost of building the damn in terms of concrete usage as compared to say the Boulder/Hoover dam spillways.

I am forced to doubt that, spillways normally means you let water spill "over" the dam in a controlled manor, which just requires some metal gates. The "glory hole" is a large freestanding concrete structure that seems like it would be considerably more expensive. Comparing the method used at the hoover dam is not really relevent because the considerable height of that dam make it impossible to employ a simple solution.

EDIT: this is what I am talking about, every dam I have ever seen in my life had that exact same construction.
