The temperature in the river was about 47 degrees Fahrenheit (8 degrees Celsius) in the early hours of Tuesday, according to a buoy that collects data for the National Oceanic and Atmospheric Administration.

Replies seem to think that I think 8°C water isn’t cold or dangerous. I don’t think that.
Water cools the body about 25 times faster than air of the same temp. A diver in 70-degree water may go blue in the lips even with a wetsuit. 47 degrees will have your body going numb super quickly. Then you lose dexterity and start having muscle cramps all over. You lose the ability to swim away or even tread water.
I’ll wear a t-shirt outside for 10 minutes when it’s 47 degrees outside. But 47 is a whole new level of cold when it’s water.
I have a little pond in the yard, so I occasionally have to reach in there throughout the year. Right now it’s close to that 47F mark, and it’s like past “this is cold” to “this hurts!”

Water temp of 47 can be lethal very quickly.

It’s bad.
