MADISON, WI (Wisconsin Radio Network) — After a number of recent tragedies, the Department of Natural Resources is reminding people to be careful out on the ice.
Fisheries Supervisor David Rowe says that while the recent snow and cold might have put more packs down on most lakes, you always want to be careful “Drill holes, check the thickness as you’re going. Six inches is safe ice, less than that, you really have to use your judgement.”
Rowe stresses that any lake or river that has moving water could have a chance to have ice rapidly thin out in places, “and so people really have to be really cautious when they’re going out on places where the water could be moving.” He advises snowmobilers to stick to established, marked trails.
