This is second hand, but if you follow the Facebook page "Palo Bite" it looks like there were people out there last weekend/earlier this week. Didn't see an actual thickness on the post, but it sounded like the ice was sketchy.
DNR report that came out today said "1-3 inches as of 1/5 and ice fishing not recommended". I would think with the forecasted temps the next few days the ice would be good by the weekend. Not sure how much snow is on the lake. I was thinking about fishing Saturday or Sunday.
