Truly an impressive project. I wish I had gotten a large excavator for my pond project. I used a regular sized backhoe and made three ponds on a small stream that runs across the front of my property. It is visually attractive with spillways and water splashing into them but they are a bit small and shallow to be really practical for farming fish. That was a great idea to set up a shooting range while working on the project. I always try to plan out whatever project I’m working on to avoid waste and be efficient.
