It doesn't surprise me that Green was turning over in late August. In the past, I have noticed that, for some reason, Green River Lake seems to turnover sooner than the other lakes around here. I knew you weren't trying to be smart about Rough and I agree, its easy to miss or mistake the early stages of the turnover.

Our God and the soldier we alike adore.
But at the brink of danger, not before:
After deliverance, both alike requited,
God is forgotten, the soldier slighted.
