Used to specify a type of inland body of water. It must be tagged in conjunction with natural=water.
Possible values
These tables are a general overview of each feature. For detailed explanation of each, refer to their specific pages.
Natural features
| Tagging | Description | Sample photo |
|---|---|---|
| water=lagoon | A lagoon: a body of shallow sea water or brackish water separated from the sea by some form of barrier. It's better to specify saltness of water with salt=yes/no. | 
|
| water=lake | A lake: A body of relatively still fresh or salt water. Artificially created water bodies should be tagged with water=pond or water=reservoir. | 
|
| water=oxbow | An oxbow lake: U-shaped body of water formed when a wide meander from the main stem of a river is cut off to create a lake. |
|
| water=rapids | A fast-flowing, often turbulent, section of a watercourse such as a river, often containing exposed rocks or boulders. This tag is only for mapping rapids area. Rapids still have to be mapped on river centerline, see waterway=rapids and for more rapids properties whitewater:rapid_grade=*. | 
|
| water=river | The water area of a river. Should contain waterway=river way inside. | 
|
| water=stream | The water covered area of a stream: a naturally-formed watercourse which is narrower than a river | 
|
| water=stream_pool | A stream pool; a small and usually deep collection of fresh water, occurring along a stream. Water velocity in the pool is typically much lower than in the stream. Frequently found below a waterfall. May be used as a "swimming hole". | 
|
Artificial features
| Tagging | Description | Sample photo |
|---|---|---|
| water=basin | An area of land artificially graded to hold water. For more details you can use basin=*. | 
|
| water=canal | A body of a canal, a man-made channel for water. Should contain waterway=canal way inside. | 
|
| water=ditch | Water covered area of a waterway=ditch - a linear waterbody serving as a barrier or for draining surrounding land. Should contain waterway=ditch way inside. | 
|
| water=drain | The water covered area of a waterway=drain - an artificial waterway, lined with concrete or similar, used to carry superfluous water. Should contain waterway=drain way inside. | 
|
| water=fish_pass | The body of a fish pass for the fish to pass waterway dams or weirs. Should contain waterway=fish_pass way inside. | 
|
| water=harbour | A harbour is a sheltered body of water where ships, boats, and barges can be docked. | 
|
| water=lock | A lock chamber outline: a part of river, canal or lake system, level of which can be manipulated. The mapping of a lock and its parts is described on wiki-site lock=*. | 
|
| water=moat | A deep, wide defensive ditch, normally filled with water, surrounding a fortified habitation. | 
|
| water=pond | A pond: a body of standing water, man-made in most cases, that is usually smaller than a lake. Salt evaporation ponds should be tagged with landuse=salt_pond, open-air swimming pools — with leisure=swimming_pool. | 
|
| water=reflecting_pool | A reflecting pool: a water feature found in gardens, parks, and at memorial sites. It usually consists of a shallow pool of water, undisturbed by fountain jets, for a calm reflective surface. | 
|
| water=reservoir | A reservoir - An artificial body of water used to store water, usually formed by a dam over a natural water course to retain the water. | 
|
| water=wastewater | A clarifier/settling basin of a wastewater treatment plant. The whole land area of the plant should be mapped with man_made=wastewater_plant. |
|
Obsolete uses
- water=intermittent: consider using intermittent=yes instead
- water=tidal: consider using tidal=yes instead
- water=cove and water=bay: the established tagging for bays, coves and inlets is natural=bay
Possible tagging mistakes

- man_made=reservoir_covered - A covered reservoir is a large man-made tank for holding fresh water
- landuse=salt_pond - A place where sea water is evaporated to extract its salt
