Thanks for the clarification, Pierre.
Actually, I tagged the relation both with natural=water, water=river and
waterway=riverbank as advised in the wiki (see New Tagging) I assume this is
the recommended way to do it?
As for Obrero, I haven't been that far north yet :) I only traced it up to the
point where someone else had traced it. I stopped around Sta Rosa:

But, yes I agree, that needs to be retraced. It was probably traced from an
old lower resolution satellite image like some of my own earlier work.
Ronny.
