ive went as deep as possible, but cant get any deeper to where the rock is. its all dry. but i dug down behind the dam where the leak shows up and water is coming through the seam between the old ground and the new ground. so i guess its just the fact that i cant get any deeper is why i can locate any water. gonna get my buddies trackhoe and skidder and try to get deeper to find it, then probably gonna have to recore it and rebuild it. i know the dirt is way to dry down there to have enough compaction to really work, so thats probably most of the problem. once this is fixed, it seems lke this thing should hold a lot better.
