Yes, that does look nice. My duck pen is on a hill so I might be able to do something like that but the digging would be the worst.
You have a very pretty pond.
I would like some suggestions on building a duck pond that would be easy to keep clean. I have a small container for a pool for mine but it would have to be dumped every day and cleaned out and refilled which is more of a job than I want to do. I would love to hear other suggestions.
