Went on a drive by today. Saw two guys heading out and stopped to talk. They had walked out a little, drilled and measured with a tape... There was 4" there. Ice was a little white, but looked solid. They set up in front of the tree off to the right of the sheriff's boat house on the opposite shore. They said there was 3 1/2 by the tree.
They did NOT go into the middle of the bay nor up the channel so I can't say what the ice is like there.
