Thanks Cecil,
As long as I do not drain the pond under high water table conditions, the liner should be fine, otherwise the ground water may lift it out.
There is a sand binder product for building swimming pools that will allow one to sculpt and do vertical side walls. I do not know the name of it yet, but you mix it with sand and water. It doesn't harden up but will stand quite firm. My sister told me how their pool was installed and that is 10 ft deep.
The garden pond is going to be 30ft x 60ft x 8ft deep. 3 sides will be almost straight down and the entrance will be sloped, cause my dog will be in it all the time.
I came up with a garden layout I like, and funds are on the rise.
It sure sucked to live in MI these past three years!
