~~~~~~~~~~~~~~~
With the speed of the current of 20 mph, it is a mountain river. Something like a waterfall.
I do not think that boats are able to travel "upstream" and even "downstream" in such a river.
If downstream, then only once, after which case a boat becomes a "scrap metal" (if it was made of metal).

Avoid travel at such dangerous conditions (!)
