Lake Berryessa, a large reservoir in northern California, has an interesting spillway called the 'glory hole'. This consists of a giant pipe sticking out of the lake. Normally it looks very strange and out of place but when the lake is spilling it looks like a huge, frothy hole in the surface of the water, or a giant bathtub drain. The water all comes out of a huge pipe below the dam. Apparently, several people have inadvertently or intentionally been sucked into this hole during flood stage and been churned to their deaths below. Pleasant, eh?


It is far too big to stick even the largest penis through, though. And trying this when it is spilling over is a very bad idea
