What it feels like to swim in sub-zero waters
Actually if you read the link you'd see one of the polar bear events the temperature was -8 degrees fahrenheit. I've watched similar events on TV where they actually cut a hole in the ice to begin the event.

Those are air temperatures, not water. Being fresh water, the liquid water is not below 32F/0C.

Nit: flowing water does go below 0°C without freezing, as does water with impurities (sea water).

That's air temp, not water temp. We are discussing water temp.

Do you mean the first photo where it says 8 degrees above zero?
