FishinRod,
I dont necessarily believe that water went over the top in the 2 manners you described. The high water line was roughly a foot or two below the "top". My "assumption" is that as the dirt on top was not properly compacted, the water either seeped through the top or eroded away the dirt. This caused the area that was a foot or two above the water line, to now be at the water line and that is how water ran over. As I mentioned, this is what I am assuming happened and I am not 100% sure. We did not receive any appreciable rain. We have actually been in a drought most of the year.
