He actually has done a few things on his dime. He tried broadcasting sodium bentonite where he thought the problem was and recently came in and dug out the portion of the dam closest to where the leak is on the other side. So I can't say he has not tried. The pond is about 1 to 1.5 acres and maybe 16 feet deep. Should I just bit the bullet and get a liner for the thing or is there a high chance of success by lining the bottom with clay. Clay is not easy to come by in Blanco County.
