It is very possible that water is flowing under the liner, lifting the liner
for a period of time and then percolating out, allowing the liner to settle
back down, making the water level go down. There have been a number of
people that have had problems with the liner floating up out of the hole,
causing a large bubble under the liner. Your soil sounds like it is more
permeable than theirs. Try raising the ground level around the high side of
the pond to divert the water away from the pond. That might keep the water
level from rising and then falling back down.

Ah-ha, there's something I hadn't thought of, and might very well be
the answer given the way the ground around the pond is configured.

I've now dug a drainage ditch about 30' uphill from the pond to
prevent runoff getting in and silting up the pond (which also happened
after the big rain).

Changing the ground level immediately uphill from the pond would be a
real pain as there is a stone patio there, do you think I could just
put a layer of rounded pea gravel on the bottom to prevent the bubble
from floating the liner up?

Thanks!
