There is a few more pictures that may help you (or not) in my pond build:

Don’t know if you looked through it or not.
This is actually the fourth pond that I built ( three were for me, one for a friend).
Not saying I know everything about building a pond (far from it), but they all did turn out to be enjoyable.
My other (2) ponds actually had to be destroyed with my old train layout after I moved on to my current life! But I did get to enjoy them for 8-years, and the fish in this pond came from my old ponds (about the only thing I won in the divorce!).
