Have you actually taken soil samples from different areas of the pondsite? What is your soils assessment based on?

No I guess I don't know where you are going, are you saying that I will be unable to hold water above this level and will need to dig it all out. No have not actually shot the elevations, just stood on the hill and looked down both sides and they appear very close. The lake does not fluctuate much, is high right now, as every lake is, we are getting rain after rain.
I have dug down through the topsoil and taken samples. I have not dug far down though. These samples when compressed in a coffee can with many holes in the bottom held water like a bucket for days. When I place soil in a mason jar half full of water and mix it well and let it settle the line on top is about 20%, which is the clay percentage that the web soil survey says too.
I am not thinking 2ft of soil brought in, more like 6" over the top of the compacted existing soil. (top soil removed)
