Okay here's the update. It's pretty good so far. I drained the pond and since down south the weather is extremely weird in the summer the pond dried enough for me to get in it and do the core. I dug about 3 feet under the enitre dam and packed it with the good clay from the middle. This clay is pretty good after a puddle sat for 1 week soaked, diggin only 2 foot the clay way dry and fresh ( like modeling clay). So goes the clay, I dont have access to a sheep foot but this thing was jumped,stompt, with 5 people including sheets of plywood lyed along the sides then pounced upon as well. I was fierce. So here comes the rain. Not as much as I would have hoped but enough to fill the pond half ways approx. 2 1/2 feet. It DID not drop at all for 2 days. But, but, but, now it has dropped about 1 inch in 3 days. Now take into mind it was dropping like a half a foot every 4 hours before. There has been no rain 95 degree temps., the pond is not even a acre in size, so my guess is extreme evap. from hot temps and/or ground soakage which I read is normal for new ponds. I sure hope I'm right, please tell me if i'm right, i need all the help i can get even the people that digs ponds i called act like they only know how to dig a deep hole and add lime in it. But so far you guys have been dead on like a broad head on a 10 point. Thanks alot...
