If the hole holds water, then anything that you use to line the hole will
float, at least until it is full of water. Once full, the weight of the
water in the pond will be pushing against the water under the pond, and it
will not float.

Thanks for the feedback. I think I'll stick with my first choice location
(low spot) and keep the pond slightly raised above the existing grade and
build a berm up-slope of the pond to divert water. The yard already has a
swale cut across the slope which should help also

Since this will be a small scale pond I'm seriously considering one of
those
pre-formed "tub" type liners. Can I assume the hydrostatic pressure
against
the sides or up from the bottom would not be an issue as it would with a
EPDM liner?

From an aesthetics point of view I have an ideal spot near the back of
our
house that can be seen from our deck, patio and kitchen window. It's
about
15-20 feet out from the house. However, my yard slopes downward toward
the
house with the slope leveling out around the proposed pond location.
The
yard slopes downward very slightly from the house toward this location.
In
other words, it's a subtle low spot, not a sizable indentation in the
yard.
It looks like a natural spot for a pond to be given this grading but I'm
concerned about possible negative impact of rain run off. I don't see
puddles in this spot so the draining seems good. Any thoughts?

Thanks.
