If it doesn't hold water then I'm calling the guy that built it. He can compact it or do whatever it needs. I asked 2 different guys multiple times about packing down the clay and both gave me the same answer which was no. It was ran over by the giant excavator not sure what size it was, so 75% of it is packed, there's just some loose dirt areas at the deep end where the dam is. I was told when we get a hard rain it will make it settle and that red clay will harden. Half an inch of rain is not gonna do it, which is what we got here last week.
