Steve, did they dig test holes to see how for down you have to go to get to your clay and how deep it goes? I assume you plan to get the dirt for the dam out of the bowl area? How far do you think you'll have to move the dirt? That can make a big difference. Some of my dirt came from about 300' away and we ran out of dirt to hit our goal of a 26' tall dam and settled for 21'. You will be surprised at how much dirt it takes.
