Hi
According to the waterway=stream wiki page
(http://wiki.openstreetmap.org/wiki/Tag:waterway%3Dstream):
/If a flow exists, the direction of the way must be downstream (i.e.
the way direction follows the flow)/
As of today there is a very small percentage of streams (17593 ways
according to taginfo, 0.23%) with oneway=yes.
Is there any undocumented purpose? Is it ok and safe to delete
oneway=yes tags for streams?
The same question can apply to drains, ditches, canals...
Yours,
