All great things to think about- thanks- I should have two rough estimates on my build costs in the next week or so- I only have an acre of property- and the wife won't let me cut out half of our house to make the pond bigger- I can maybe get it to about 90 feet by 60-70 feet (triangle shape). Again I don't mind the well idea, but what to do with all that overflow water is a problem. I'm sure we'd be incorporating a nice big waterfall on one end ($$) and I guess a diffuser near the center. Does that sound like adequate aeration? And I'm wondering if more aeration allows one to get away with a smaller pond as far as maintaining numbers of gamefish? Again if I could do anything I would maintain a blue gill, LMB pond- but HSB and CC, or trout all sound great too. I really appreciate the input.
