We were up to Nelson this last weekend... The ice is about 20 inches thick... In 3 days we had caught 19 Northerns average of 4 pounds (biggest 15), 6 walleys (biggest 4 pounds), and lots of perch. We were using 3 inch minnows on tip-ups. We were fishing north of the boat ramp in 15 to 17 feet of water. Make sure you take your ice cleats (no snow on the ice). Wish you the best of luck
