I pulled the liner today from the pond and stream. I was surprised to see the amount of roots, depressions in the liner and roofing felt disintegrating . My plan was to use the roofing felt (#15) again as an underlayment but now I am concerned this is not enough of a barrier. The pond was going into its 5th season before I decided to expand it. Should I use a different material for the underlayment?
Top picture is the underside of the 45 mil liner. The second picture is the #15 roof felt on top of the ground.
