Thanks Rainman. The sand-small sandstone area that we believe the seepy material came from was not in the lake bed, but it was past the north end of the levee up the hill a short way. It was the closest and most convenient location and none of us suspected it being sandy. They didn't work there long till they saw the sand and have hauled some of it to the levee. I have pictures of that I can post later today.

As for letting it do a slow and natural drain, that's basically what I've decided to do. I haven't touched it since May and decided to let it seep all summer and that it would find it's natural leveling off point by August, September at the latest. It's probably there now.

All you think it needs is the sheepsfoot roller over the whole thing? Should I add Bentonite/Pondseal first? Or just use the shepsfoot roller on the clay soil I already have?

I'll see if I can post more later today. Thanks for the reply and I look forward to anything any one else has to offer.
