That is a really nice looking set up. Any ideas on what size pipe you would use for this? Is the pipe that goes in the pond and down the back of the dam buried under the surface or is it on top of the ground.

So if I am looking at this right, this is an overflow pipe and a siphon all built in one. Am I correct???
