If you're thinking that looks like somebody pulled the plug on a huge cartoonish bathtub drain under a lake.... well, that's exactly what it is. That's Lake Berryessa in California, and the "drain" controls the water levels in the lake. According to the site the photograph is from, the drain is big enough to swallow your house (about 70 feet across) and it goes down almost 300 feet.

Very cool! Too bad they didn't post the design drawings

Thats freaky..

I like how they put it right next to a street so if a car crashes and falls in the passengers have zero chance of survival hahahahahahah

The Owyhee Reservoir a few hours from us has one of these, they are crazy!!

Kinda freaky

My guess is that this "device" ,if someone can call it like this ,is a water extraction device.It is a part of a dam and its called Morning Glory.The name may seem familiar to some of you as it is the name of a flower.And yes ,its kinda freaky and scary and everything...

Got to love engineering
