I've found several threads on here about ponds. What if I want something just big enough for the kids to fish in? I would have marginal plants in the ground, but no pump or anything. Maybe some Blue Gills or some kind of other pan fish. We had a large pond planned but prices have gone up on everything and now thats on hold. I'm looking for someone to tell me __x__ feet, by __ feet deep to get a size fish can survive in. Any ideas? This is in WV.
