A 30-year-old Sartell man is in critical condition after falling through thin ice in Benton County. Joshua Johnson was ice fishing Friday morning on Little Rock Lake when he went through the ice. Rescuers were able to pull Johnson from the water. Officials say the ice was about an inch-and-a-half to two inches thick. Authorities are warning that any ice that has formed on the lakes is not safe for travel at this time.
