I know several ponders who have ponds with no waterfall, no pump, no aeration what so ever. They are liner ponds stocked with feeder goldfish. And they are beautiful. Very peaceful and still. Now, that's not to say those ponds are neglected - they still scoop debris and trim plants and use netting as necessary to keep leaves out - they just don't have any water movement. There are all kinds of ponds out there. It all depends on what you want.
@Lisaebetten I think a lot of what you read about ponds and the heavy emphasis on water quality comes from the koi pond side of the hobby. That's a different endeavor than keeping a garden pond, in my opinion.
