Brett, I'm not qualified to answer this and doubt that anyone here is. For the most part, we don't build them but manage for fish after having them built.

I do have a concern about the slope in a residential area.


It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
