I checked ice on Wed. 11/28 on a lake not far from Owasso and found 6 inches on each hole I cut. Clear black ice. I went out quite a ways. Although it looked like a lot of ice towards the middle was freshly frozen, there was a distinct line where you could tell the water froze at different times. I did not check that ice, it may have been walkable but I just stayed left of that “line”. I plan to go out Saturday afternoon/evening.
Stay safe everyone!!
