This picture shows the process of the track hoe digging along the banks and putting the clay into one of 2 dump trucks to be trucked to the dam. You can see the spillway pipe sticking up - the dam was built up about 5 feet higher than is currently shown.
After the trucks would dump their loads, the dozer operator would smooth everything out. We then used a vibrating roller to compact the clay. Even though I contracted for the whole job to be done, I ran the vibrating roller. Took a couple of weeks of hauling clay, spreading it about 6 - 12 inches thick, compacting it, then start over again. I did not get any pictures of the roller cause I was running it.
