Status: de facto

An area of land artificially graded to hold water. Note that this definition includes also structures typically without water. Usually these features are made for man made water courses e.g. storm water, water treatment.

It is treated as synonymous to natural=water in many renderings, including JOSM editor.

iD editor instead considers landuse=basin as "outdated" and suggests replacing it with natural=water + water=basin.

How to tag

Applies to node nodes and area areas.

Tags used in combination

  • name=<name of the basin>
  • basin=* - refines the type of the basin
  • intermittent=yes - If the presence of water is intermittent.


River basins

Do not use this tag for land form (natural) basins e.g. the Amazon Basin. There are no tags (yet, 2018) in OSM for mapping such features.

Possible synonyms

If you know places with this tag, verify if it could be tagged with another tag.
Automated edits are strongly discouraged unless you really know what you are doing!
