If there is one thing that I have learned whenever you undertake a HUGE project like this is it pays to do it right the first time LOL.
A leaky dam is a PITA on a one acre pond.
That looks like a lot of clay there. It sounds like you have a good dirt guy so I hope that everything works out perfectly for you.
You know, I used to make fun of my ex wife for following other people's "blogs" on stuff...usually DIY home projects or whatever...now I feel just like her. I wake up and I'm like, "Man, I hope that there are some new pictures of the pond" LOL.
