Pond Boss Forums POND CONSTRUCTION Building a dam New Pond Construction In Jefferson Co, Mo.

Thanks Rex!That's the way I was thinking it worked but the way I was reading some of the post on here I started taking it as the bowl had to hold all the water or it would leak no matter what.
I don't know how much water soil will hold?I know I read somewhere, someone said the ground around a pond can hold as much water as the pond it's self.Considering we've been in a bad drought every since it was built,I don't know if I've lost enough water to saturate all the soil in front of the core.
When we dug the test holes we hit the best clay at around 2.5' and we went down to 8' and the clay was still good but it started getting harder packed.He said that was the depth that he wanted to cut the core trench, and he claims he stuck with that plan.
