The Blue Earth County Sheriff’s Department continues to warn people to keep vehicles off the ice on all county lakes. This comes after numerous incidents of cars falling through thin ice, including a death last week on Lake Elysian. The day before that, a Mankato man plunged through the ice on Washington Lake in his car. He was able to climb out the window onto the roof, and was hospitalized for hypothermia after his wet legs froze to the metal roof as he waited for rescuers. A car broke through the ice on Madison Lake on Wednesday as well, but no one was injured in that incident.
