The Dodge County Sheriff is warning residents about dangerous ice conditions on area lakes. Sheriff Dale Schmidt says rescue personnel responded to two separate incidents of vehicles breaking through thin ice on two different lakes Sunday. Schmidt says fortunately nobody was hurt when vehicles went through the ice on Fox Lake and Lake Sinissippi. In the Fox Lake incident a man was fishing with his pet dog when his vehicle went through the ice. The man was arrested for OWI 5th offense and transported to jail.
