(CBS 2 Chicago)

With the lake water below 50 degrees, anything more than a quick dip can potentially lead to hypothermia. It´s especially dangerous for boaters who may decide to jump in. `If your airways are below the water level when you take that gasp of air which is involuntary, you suck in that cold water in your lungs, it´s going to cause cold water drowning,` said U.S. Coast Guard, Matt James.
