I was wondering if rock means no dice on the dam construction. I took my dozer and dug a hole to see what the soil looked like, and to have one of the local contractors look at it also. I hit a bed of rock at about 4 feet. I took some digital photos of the hole today and noticed there was some water in a hoof print one of our colts had left in the hole. Not sure if that's good or bad. I do have good clay up on the hill. This site is down in a dry creek bed that runs water only during heavy rain. If I knew how I would send the pics so you guys could look at the hole.
