Pond Boss Forums POND CONSTRUCTION Selecting a site Please help newbie pond builder

I have plenty of room but my old back and my old backhoe have limits and I want my pond right now. (It's an OCD thing). I was planning to dig a hole in the side of this hill about 10' deep and 35' in diameter. This is 0.022 acre. I could make it bigger, I could make it 50' x 30', How big do I have to get to have a decent minimum fish production. I want to eat 8 fair sized bluegills every two weeks.
I am thinking I can harvest minnows and crayfish from my little creek and relocate them to my new pond and then add bluegills shortly after that. I do not plan to feed them or aerate. Just a natural, near zero maintenance pond I can pull some tasty bluegills out of occasionally. They do not have to be monsters.

How far back should I cut the surrounding trees?

I was planning to have floating containers with watercress and goodies as well.

I am not building a dam, it is not in a ravine that will cause much threat of overflow. It is near the bottom of the hill where the groundwater level is always high.

This project is part of my off grid life as detailed at https://www.nogridhome.com

Ideas, suggestions much appreciated.
Thank you!
