Hello,

I am going to construct a 3000 gal pond in my back yard and have a question
about construction in/on a high water table location.

I have filled in my back yard which is on a sloping hill towards a marsh.
One side of the proposed pond area is approximately 4 ft. deep (2 ft. above
water table) and the other side has been filled approximately 6 ft. (0 ft.
above water table) to level off the land. The fill is 90% heavy clay.
Prior to filling in the yard I had surface rain water flowing by towards the
marsh area.

Now for my question...I was planning of keeping the shallow side of the pond
at 4 ft. and the deeper side at 5 ft. I have read that if a liner pond is
constructed directly on the top of a wet land, the liner will bubble up.
But I have also read in my new book "Koi: Living Jewels of the Orient" by
Steve Hickling that if the water table is high one can dig a sump, pump it
out during construction and lay the liner. After filling the pond one can
fill the sump back in. Am I missreading this section? If the liner is
layed out and the pond is filled then there should not be a problem with
bubbling underneath the liner?

I know that I can build the pond a few feet higher to remedie this problem
but, BUT...
