It's the standard to draw a waterway in the direction of flow. I've
questioned this several times, but it's an ingrained default.
My question is more specific: what happens to a drainage canal that
reverses direction? I offer the Everglades and surrounding agricultural
land as an example.
Interesting question.
I do have do navigable canals that can have the water flow in either
direction, under operator control. I think there must be many of them.
I so far have not bothered about the flow direction, as boat traffic goes
both ways independently of the actual flow of the water, but

So there are a lot of major canals that have no fixed direction. How
should these be mapped? Is there any existing scheme that can show how
water flows under different conditions?
We have this abandoned proposal for explicitly mapping flow directions:
In many European canals, the convention is for the waterway authorities
to arbitrarily define a direction so that a 'left' and 'right' bank can
be defined and the appropriate navigational marks installed. So in those
cases, where you see red on one side and green on the other, the

oneway=no would make sense, since the (unusual) default assumption for
this type of object appears to be oneway=yes.
It's possible that there are places where the waterway is legally
restricted to travel in one direction.
