Thanks for all of the info. They are not going to use the mud. It rained here this morning and there is no way to walk the mud around the dam (which may be a blessing in disguise) without causing all kinds of mess. The have let the water from the pit flow into the pond. They pumped out the original water and this is just rain water with a little mud residue in it. We'll see. We're expecting 3 days of rain! Thanks again.
