I did another soil test tonight.
Please look at the updated pictures here(

I seem to have a variety of clay types.
I am located in Western New York seashores.
This pond site is about 40 miles north of Buffalo NY.
I'm being told by some that 20ft deep is too deep:
"If you don't mind me asking, ETD66SS, why is your proposed pond going to be 20 feet deep ? The oxygen content of any stagnant pond is highest at the surface, but then tapers off as depth increases such that beyond 8 to 10 feet water depth you are looking at a virtual dead zone with insufficient oxygen to sustain aquatic life.
If you plan to feed your fish stock, a good deal of that feed will sink to the pond floor without being eaten if the pond is too deep, and will rot there, polluting the water. When cold weather sets in, the surface water of a deep pond will increase in density and move downwards, displacing poorly oxygenated water up from the depths to the surface - a phenomenom which can cause sudden fish stock die-off.
Finally the cost of excavating a very deep pond will be orders of magnitude higher than the cost of digging a shallow pond, with no advantages that I can see, other than providing deeper refuge for the fish if the pond is located in an area where the surface is likely to freeze over in the winter."
Is 20ft too deep for the size pond that I plan to dig?
