Pond Boss Forums POND CONSTRUCTION Creating habitat 700 sqft pond - Can it be natural & sustaining?

There is no creek that flows into the pond. But my area gets 50" of rain a year; it has that water coming in, plus I could channel rain water from the property into the pond.

Yes individual fish will be there for so long only, but I am hoping the stock will be there forever by reproducing. I sometimes see unattended ponds with a film of god knows what on top of the water. I wonder if something like that might happen to my pond if I don't maintain it.

This property is 3 hours from where i live, so maintenance is a bit hard. Yes I still intend to build a bigger pond, but I want to test this small one out first (particularly to determine whether I can avoid using liner), before investing in such a large scale project.
