Hi Charlotte
This page may help:

As it says you should still include a way tagged as waterway=river to
indicate the flow direction. This can be changed in Potlatch if
necessary by selecting the way & clicking the arrow icon in the bottom
left of the screen.
On this way I also include a width=* to suggest the width of the river,
but as this is rendered, if this isn't accurate & not dead centre of the
riverbanks it may overlap with them.
As you suggest, it's best to divide it up into smaller sections. I try
to place them next to river crossing, but as yours is very wide that's
probably doesn't occur very often.
Often it helps to send a permalink (bottom right of the webpage map) of
the area your working in so the others can take a look.
Hope that helps

Hello everyone,
I've been mapping the Little Colorado River, which, despite its name,
is rather large, bank to bank. When it's not encased in a canyon--such
as when it gets close to joining the big Colorado--it's a typical
Western U.S. river: a quarter-mile wide and a foot deep. So, in the
places where it is wide, I've been mapping it as two riverbanks.
However, it sometimes renders as a large area of water, covering
places that are not under water.
I know we are not supposed to map for rendering, but this result makes
me think that I am doing something wrong.
So, what is the correct way to handle waterway=riverbank? Do we join
the two banks from time to time (as I have done to try to correct the
problem)?
The area I have mapped is in northern Arizona, around the towns of
Cameron and Winslow.
Thanks in advance for your help.
