Wow, this entire thread has been a interesting read. I am where you were on page one. I've just cleared two beautiful acres of woods to build the pond I've been dreaming about for years.
I was trying to avoid every problem you've encountered. I had the USDA pond expert out,then I had a guy come out with a back hoe to dig test holes, then I had the USDA guy come back, and he brought his soils expert. They all gave me the go ahead, even though there were some rocks in the test holes. The clay was very good (ribbon test etc.)
Then we took out all the trees, and started dozing. We found even more rocks.. Not good. I paid a pond expert/consultant to come in and help with advice etc..
I almost shut down the project due to finding more rock, but decided I was already in pretty deep $$ wise.
Got it completed, and now I'm in the waiting phase to see if it will fill, and hold water. We found rocky sections with some 6 to 8" rocks in the clay. They tried to excavate below them, but they didn't end.. So they just ran the Sheepsfoot roller over them again and again.
Walking it the other day I think I've found one pretty big rock, about three feet across that is visible in the clay. It must have been scraped over near the end. Will it leak around that, it is in a shallower part of the pond, but will still be in 8' of water.
Oh well, it is what it is. All I can do now is wait. I'm not investing any more in fishing structure, until I see if it holds water.
Your pics look a lot like mine .. Hope you get this solved. I figure mine will be a huge two acre food plot if it doesn't hold water..
