Thank you for your responses, even if they are mere opinions. Thats all Im left with right now anyway are my own intuitions. I have the same thoughts as all above. I have YouTubed dam builds in the winter and see big equipment running and building with snow on the ground and dams being demo'd with frozen water. I also have the same opinion that the dam must completed in one day. At this ole coot's pace, that ain't happening. My fear is that if compacted layer by layer then a new leak will appear there.

God has blessed us with this day, what we do with it is up to us.
