The pond held water without any leakage. I just wanted to know if I was creating a problem. I am digging to sandstone to about 3-40' of the dam. How much dirt? Hmmm. As much as I can in area but just down to sandstone as far as depth, that being from 3-8 feet. I am about half done. In the end it will be 3 acres.

I am doing it myself with a d5, d6, 150 trackhoe with 6' cleanout bucket, and a cat 830mb four wheel drive scraper with a 20 yard bowl. I used the scraper as long as I could and until I kept getting stuck now I am top loading it and moving it into an adjacent field. I will try and send pics.
