with pond size, at what point do you not have to worry about. i ask because i see ponds in the woods that are like 60x60 and the fish are thriving in it. i will be moving to my dads very soon in west virgina, he has 15 acres there and im gonna try and build a pond, but i wanted to go MONSTER, like 200x200 and about 5-10 feet deep. i want something large enough i could stock native fish, like channel cats, both lmb and smb, blue gills. would it be fine to dig it up, let rain water fill it, thought that might take a year or so and add fish?

. It can be done with a tractor with a backhoe and a blade, but a dozer would be nice.
