Fishkeeping - Raised pond - hiding the liner

I plan on using something like this

I am going to make two walls back to back and put the liner between them.

I am thinking of redoing my yard and going from an in-ground pond to
something that is part in ground and part raised. I would build it out
of cement block and then face it with some sort of stone. I am
wondering how the liner can be attached to the sides. Since it is
going to have to be hidden by top stone, I assuming that I won't be
able to ever fill the pond to the very top since the liner will stop at
the second to last row of stone. I am thinking the cement block will
be capped off with a 2" thick cobblestone type block. I am also
wondering about what I need to keep the out of the ground part stable
given the pressure of the water pushing on it.

I have a very small yard and the raised pond will increase its
visibility from the house and the ledge will double as seating for
viewing the pond.
