You suggested that:
Some (or perhaps many) wilderness visitors are city-dwellers or non-English-speakers and therefore the warning system of sorts must be improved to protect their safety in the great outdoors...
I don't agree with that.
There is this amazing, newly-invented technology that we should all use. This amazing new technology is called "common sense". This breakthrough device, called "common sense" tells me to stay the heck away from flowing water.
It tells me that when I have hiked three strenuous miles, the last thing I should do is obey my irrational inclination that urges me to dip my feet in cool, running water.
In the Yosemite Nature Notes video on Youtube, entitled "Wildnerness", there's a short segment where (I believe it is) a ranger discusses the character of the outdoors. He says things to the effect that "Risk exists, and it's up to US (not the NPS or the gov't) to make decisions, to weigh the pros/cons, and to not be idiots.
Edit: If I go into the wilderness and get hurt or die because I break an ankle or slip into the river, or am crushed by a falling tree, there is no one to blame but myself-- a person who made the decision to go out there. It is not the park service's fault or the government's fault because they didn't give me enough warning. Any sensible person will know that the outdoors involves risk (just like stepping out of my house to grab the newspaper off the driveway etc). We don't need more signs and more safety tests.
