Is there a way that I can secure the piece of pond liner to the inside of the
35 gallon pond so that water cannot get in underneath and drip out on the
ground?

For a similar thing for my last pond I just used normal white silcone
sealent. Allow 24 hours to cure before applying water to remove the risk
of any fungacides being washed into the water.

I suspect any flexible sticky stuff in a tube would do the job.
