I have a 10 x 10 (foot) bog garden.
It is lined in rock.

In four years it has completely grown over.
All the dead plants over winter have turned into
nice slurry stinky mud, wonderful fertilizer!
It will be weeded this fall and we'll start over again as a shallow pond.

But to answer your question, yes, the clay will eventually settle out and the
pond should do nicely until it needs to be weeded.

I would not do mine differently, except use pea gravel instead of river rock,
as it is hard to walk around the bog over river rock.
