Ice on the North end is around 6-8" now and the whole lake is froze over minus an area straight out East of the beach in the main lake that the geese kept open. I would say any bay would be safe for foot traffic now, but would definitely shy away from ATVs for another few days. Fishing has been really slow this last week with these temps. Few bluegills and crappies have been caught. I haven't heard of ice thickness in the main lake so use caution the further away from shore that you travel.
