It’s one of the leading causes of death in boating.

The leading causes of death in general aviation are the weather and running out of fuel.

It's a not unheard of cause of death in the Grand Canyon as well. Someone gets up to take a pee at night (you're supposed to pee in the river), maybe they're a bit drunk, and they fall in and get swept downriver.

On river trips when camping at night.

Though people have also died pretending to fall from the rim and then they actually do. (You don't normally fall all the way--the walls aren't that shear--but you fall far enough.)
