This is a photo of something called a 'glory hole' in the middle of a reservoir, and I find it somewhat un-nerving.
Apparently this is the second largest hole in a lake, at 22m diameter. It is the top of a pipe which controls the maximum level of the reservoir behind the Monticello Dam, California. Effectively it is the top of the overflow pipe like the one on your kitchen sink.
