So I have a small pond already. Maybe 1/4 acre ish. Not really sure how deep but it’s fed by a natural spring. I don’t think it’s too deep but no pond vegetation and it never has algae. It’s also rather lifeless as far as we can tell. I can see down about a foot, then it gets murky and can’t see. It’s the only natural water around here that I can honestly say I’ve never seen dry out even in the droughts to where I can see bottom. It’s full right now of fallen trees and I’m gonna clean it out. Trying to decide if I want to drain the thing into the creek on the one side and then backfill it and let it fill back up. I don’t want to risk destroying the natural hard pan.
