Drove past Blue last week just before Christmas. Stopped to talk to the folks as I had not ice gear with me on that trip. Ice was out about 40-50 yards past the Lake City bridge. Only a few were fishing past the bridge (within 25 feet of the bridge). Others were fishing east of the bridge in about 12 inches of ice in 18 feet of water. Browns and perrch were being caught at a pretty good clip early in the morning but slowed as the day went on apparently.
