I found this early picture to show how the project began. http://farm3.static.flickr.com/2062/1736251504_fc3bdd5487_b.jpg The field had a slight depression so I began to dig and use the spoils to level the sides. You can see the water in the test trench I dug first. It has been at that level for the last 3 years! The material being removed is almost pure beach sand so its easy digging but a bitch to drive out of. The area is approximately 400ft by 500ft and 15ft deep. I should be done with this phase by December as I will be to the water table. Next I will have to hire an excavator to remove 3 more feet of sand which gets me to the clay that I need to line the sides. Then I will rent a compactor to assure a good seal. I have 710 hours on the b7800 so far with no problems.
