Not only that, but as it was described years back* ("Maybe you can just jump
over it." from January 2008) did not seem like a hard set rule, but like a soft
description.

Ah, but in England we have some Streams that are bigger than Rivers.
Stream is sometimes used when a river divides into a number of channels,
and some Rivers retain that name even in their upper reaches when they are
pretty small (and easily jumpable). So you can't always rely on the name.

As ever this is an interesting question, when is a river not a river,
when it's a stream? Or when is a stream not a stream, when it's a river?
Reading some articles: http://water.usgs.gov/wsc/glossary.html#Stream
and http://en.wikipedia.org/wiki/Stream and

I think the whole issue should be split into two separate questions: The
verifiability of the rule and the rule itself.

+1, it also depends heavily on the surroundings (surface, steepness,
solidity of the riverbank, ...) if you can effective jump over it, just a
small width doesn't tell you anything if this is a barrier to a
Having a river run into a stream seems strange (unless something (like a
drain or evaporation) reduce the amount of water in the river), or the river
is split into several streams.
I'm repeating some of my arguments from the import list, hopefully to get
some discussion on how to use these tags fr
