If there is verifiable intermittent waterflow you should tag it
waterway=stream + intermittent=yes or waterway=river + intermittent=yes,
possibly also seasonal=no if waterflow occurs sporadically and not on a
regular seasonal basis.
If you are unsure if there has been continuous waterflow in recently
times at all you should not tag it with the waterway key at all.
If there is a visible track used to drive on a regular basis this should
be mapped separately as highway=track - the track will not be identical
to the streambed center everywhere.
Note not every route that has been used by a vehicle is to be tagged
highway=track, it has to be used on a regular basis and the route needs
to be geometrically defined (i.e. cars use the same route as the ones
before). For example these are not hundreds of highway=track:
