I fell in the ice hole a few times back in my younger days while chopping holes for the cows to drink. It ruined my day every time it happened. I'm glad you didn't go in.

It hadn't occurred to me that the gray color might be from all of that lime dust, but it makes perfect sense. A whole lot more crushed limestone went in compared to the amount of bentonite.

I used my chainsaw to cut a hole, gave it some time to settle, then went back out and dipped up a sample. To me it just looks like nice clear pond water with a bit of a bloom going on. The lighting wasn't the best for the picture, but the water in the bucket has a green tint to it.

I'm thinking the best thing to do right now is to do nothing.
