Fished last week in frigid temps. Thank God for heated shack! Had 8-10 inches of ice but top 6" or so was slush that had refrozen so wasn't very strong. Use caution!
Fished in 10' of water. Managed a dozen or so decent crappie and 1 northern on jig poles and tip downs. Small blue or orange jig with small minnow, about 2' off bottom. Nothing on tip ups with 4" minnows.
Tight lines, stay safe.
