I was went out of the hotel yesterday there's a 2 foot gap between rocks and ice i had a 4 foot plank worked fine. The ice was still 5 to 7 but I could only get as far as nine feet but the perch were in there. I don't know what this wind is doing to it now. But where I fished Tuesday it was open water now. I also studded everywhere I went use caution if you try it
