I have three possible pond sites on the property. The one I am leaning towards has not had a test hole dug. With experience now on the land and looking at historical soil type surveys I am not expecting to find any thing other than loamy sand.
Last summer I had a local excavating company with experience installing ponds come out to do a site survey. To be fair he did not bore any test holes but did say my options was either a trucked in clay liner or artificial liner.

I have scaled back the size of the pond as its intended to be a wildlife attracting feature rather than a fishing, swimming or landscape feature. I now have larger equipment and was going to attempt the dig and lining myself.

Bob, as a side note I see your from Jefferson County. I ran a gunshop/indoor range in Imperial from 1984 to 2002. Jefferson County is a pretty county!
