Thanks to all who answered.
Looks like I need to add some clay to a few potential problem areas and keep my fingers crossed.

Got a good start on the dock on Saturday.
One setback though - I notched the old telephone poles for the joists that will support the dock surface and now I have a nasty rash - chemical skin burn from the sawdust !!!!

Oh well, live and learn....
