Thanks again Augie,

My plans are generally based upon; determine the optimum situation from Pond Boss, and then apply that as much as the actual ground conditions will allow.

My planned ponds are mostly out in the middle of a grass field. The final pond dimensions will be accommodating to either favorable or unfavorable soil conditions.

At some point I will be excavating on wet clay. I have already arranged with my "big HP tractor" neighbor to pull me out if (when) I get stuck.

I will be much less embarrassed to make the call since I have given him prior notice that I was going to push the limits and almost certainly get stuck!
