Yea,
My contractor knows ... its been a pain and will continue until completion with how wet it is. He has a 12-14 foot spot dug out that he has been pumping out water while he has been taking away soil from the other area of the pond. I suppose at this point I will just have to wait until the entire pond is dug out and we can take a look at where any potential water is coming in before deciding which options might be best.
I have my contractor working on a quote now to haul in / put the clay down. I also received a few liner quotes back from various companies and it seems like a liner would be the cheaper option at this point. My biggest fear is the bubbling effect it can have. The companies I have received quotes from haven't been to helpful on advice with the situation... they just sell the plastic I'm told haha.
FYI, a pond construction project that I consulted on had a really, really GOOD dirt mover. His fix to digging a pond with ground water? He would put a french drain all around the perimeter of the pond construction area about 25 feet away from the perimeter of the pond, 5' deeper than the max depth of the pond. Then he'd attach risers to the french drain and hook up pumps to pump the water out. Pricey, but it worked and they didn't have to touch a thing once all the pumps were installed other than to fill them with diesel fuel and prime them if they lost prime.
When the project was completed, he'd dig 5'-10' down at each riser, cut the risers off and backfill, leaving the blocked off french drain in the ground.
