Despite some frigid temperatures in the last week, conservation wardens and recreational safety specialists are reporting that most lakes are still not safe for any type of ice travel. Some smaller lakes in northern Wisconsin have areas with 3 to 5 inches of ice, but also have areas with just an inch or two. Ice depths can change on the same lake in a very short distance. Larger deeper lakes in the north have just begun to ice over. Some smaller lakes in the south have also iced over and have from 1 to 3 inches of ice, which is not considered safe even for foot travel. Larger deeper lakes in southern Wisconsin are still open and there were even still some open water anglers reported out on Lake Geneva this week.
