Then what would you call a natural waterway that is too small to be a

The Wiki says that a stream is small enough to be stepped over, but
gives no lower bound.
I can't think of many permanent watercourses around here that are
small enough to step over. Rock-hop, usually. Sometimes wade. I
personally don't switch from 'waterway=stream' to 'waterway=river'
until I'm telling myself that I might someday want to map the banks.
You can rock-hop https://www.flickr.com/photos/ke9tv/21811867291 in a
dry season if you're more coordinated than I am (I wound up with boots
full of water), but at 30 m across it's still a river. In springtime
that crossing is completely impassable.
The wiki description of a stream surprises me. I always thought of a
stream as something too big to step over. In the area where I live,
smaller waterways are sometimes called "ditches" (even if they're
natural), and sometimes they're called "drains." There is even such a
thing as a "legal drain," which carries certain restrictions and
requirements.
