My wife and i just built a house, and the lot we purchased had a dug pond shared with the neighbor. The pond is about 50-60 feet in diameter and 7-10 feet deep. It's currently only for runoff, but i plan to do some work to get it up and running. I have aquarium experience, but this will be my first pond. We finally thawed, so here are a couple pics. The first pic is from a raised ares on the NW side of the pond, facing the neighbor. The second is a little further back from the same area, and the third is from the SW side of the pond. You can see the raised area on the left side of the picture.
