If the pond is higher than the surrounding ground, as is recommended to
prevent runoff from running into the pond, then as you fill the pond, and
get the water level in the pond higher than the surrounding area, the water
under the liner will flow out from around the liner. If not, and the soil
is somewhat permeable, not pure sticky clay, then in time the water will
percolate down into the ground. If the soil is pure sticky clay, you may
need to put a pipe down along the edge of the liner and hook a pump to it to
get the water out.

Well, I thought I was so clever moving my waterfall to a better spot on my
pond, but imagine my surprise when I came home (with 2 new koi) to an
almost empty pond. Yes, I had not checked the placement of where the
waterfall was coming out well enough and it was dripping back behind the
liner causing it to lift up in several spots and empty out the pond.
So I'm filling the pond back up with water and plenty of declor, but
will the water that is under the liner eventually soak into the ground so
that I won't have these raised spots forever I hope?
