So dug some test holes, 2 in the base and 1 at each bank. I have a yellowish brown clay at 8 inches down. It continued to 3.5 ft or as far as I could dig with a post hole digger. I completed a buket test with 6 inches of material compacted to 3. Drilled 5, 1/4 inch holes in the bottom of the bucket. Filled with water and 15 hours later the water might have dropped 1/4 inch tops. I will post pics of the clay material as soon as I make a photobucket account.
