Looks like my pond will be 15 to 20 ft deep, on one end. Its about 1 acre total in size. This is not what I had planned. But, because we used alot of the clay lining the driveway they are having to scrape deep to get enough clay to make the dam. So,,,,is this to deep? I have alot of top soil I could push in the bottom after the dam is finished but wanted to ask your opinions. I worry the dam will not hold this much water force due to the way they made it. They pushed clay up about 3 or 4 ft and ran over the top of it with the dozer once or twice. Then pushed more and did the same. I questioned them about this and they said this is the way they did it all the time that it would be ok. Getting nervous because this is not the way that I thought dams were made. Should I calm down or stop the show?
