Use waterway=river for larger natural waterways. For wider rivers you may also wish to indicate the width of the river using waterway=riverbank. For a natural area of water use natural=water and for a man-made expanse of water use landuse=reservoir. Note that the linear ways should form a complete routable description of the watercourse. For small waterways that can be jumped across by a fit adult use waterway=stream. For a man-made waterway, created for use by vessels, use waterway=canal. For smaller man-made waterways used for field drainage use waterway=drain.

How to map

See also: Waterways

To map a river make a simple way. Add the waterway=river tag to it. The direction of the way should be downstream (i.e., draw the way in the direction that the river flows).

Just as with highways, it is important that the topology of rivers is correct. That means, if you can go from one part of the river to an other part of the river via the water, there has to be a piece of waterway=* between them. This implies that a way tagged as waterway=river should not stop on the riverbank of another river, but should proceed to the central way of the other river.

Additional tags:

  • name= for the name of the watercourse in the local language if known. For example 'River Thames', 'River Nile' (note that this should be 'River Thames', rather than simply 'Wey').
  • Use the name:xx tag format to add the name of the watercourse in another language, for example name:fr=La Tamise for The Thames.
  • width=* to indicate the width in meters. This is an approximate average width of the river throughout most of length of that bit of river. You can use width=5 or width=5 m to tag a river with a width of 5 meters.
  • depth=* to indicate the depth of the river. This is the maximum depth of the river, averaged over the length of that bit of river.
  • maxwidth=*
  • maxheight=*
  • maxlength=*
  • maxspeed=*
