I just got back from a little road trip to Walled Lake and Wolverine Lake. Both Lakes are mostly ice covered and checked the access sites at both lakes. About 1" to 1 1/2" inches of ice on both. Looked like someone even had two tipups out in front of one of the homes on Walled Lake.
There was a very small lake/pond next to Wolverine Lake at the corner of Commerce Road and Decker, not too sure what it is called but there were two guys right out in the middle ice fishing. I wouldn't have been too comfortable with it but they didn't seem to mind.
