Interesting article Alicia, I was not aware of the actual numbers.
One thing in particular sticks out, and as Bill also mentioned, the high percentage of young males who get themselves into trouble for various reasons. With age, I have learned to temper my adventurous impulse to "Just go do it", with more calm and reasoning. Now I plan things, consider the risks, and listen to advise from peers and those with more knowledge than me.
I have always been fairly open to advise I think, but did not always seek it out.
The picture below is a section of the Hiawassee River just below the Appalachia powerhouse in Polk Co. TN. where water is released to power hydroelectric turbines. The area is a popular place for trout fishermen / women. It is a great place to wade fish.

This picture shows the water level at minimum flow, no turbines running. In most places the water is no more than waist high except in some of the deeper holes, at the minimum flow level.
However, when the dam releases water, the water level can rise rapidly, trapping anyone out in the middle who was not paying attention. This can be a deadly situation for wade fishermen! All the rocks you see in the picture can be up to three feet under water at full flow!!
The Cherokee NF has signs posted warning of the dangers, and telling fishermen to wear PFD's. If you pay attention to the water level you can easily wade out as the water rises, not everyone pays attention for some reason, mostly younger males in my experience.
I always try to encourage these guys to be more careful, it only takes once, to get killed I tell them.
I've been asked to mind my own business before, told I worry too much. One young guy who I offered my extra PFD to, actually said to me: "&%#$ that, I've got waders on! Why wear a vest?"
Each year some of them drown, in one river or another. Sometimes it's the older ones who have grown complacent, some also love to mix fast water with alcohol. In any event, S&R usually ends up being just a recovery.
