Is there any existing tagging convention for such seasonal or dry streams?

A typical example of such a dry stream can be seen in the satellite images
at this location:

I used an 'intermittent=yes' tag for a county-wide import I did. I remember
it as being an official tag, but when I can't find the documentation now, so
it's likely that I am simply misremembering. There isn't support for the tag
from Mapnik or Osmarender, so if there's another tag that does have render
support, I'd like to know too.

FWIW, I also use intermittent=yes.

It sems 'obvious' :-) that this should be

  waterway=stream
  stream=intermittent
