|Tools for this tag|
The waterway key is used to describe rivers, streams and boat-yards. Some 'water' related features use other tags, including
By convention the direction of the way should be downstream (ie draw the way in the direction that the water flows), when known.
If water is seasonal, use the tag intermittent=yes
|waterway||river||For narrow rivers which will be rendered as a line. For larger rivers (defined as more than 12 m across) see waterway=riverbank (Other languages).|
|waterway||riverbank||Used for larger rivers, to define an area between the opposite riverbanks. See water=river for alternative tagging.|
|waterway||stream||A naturally-formed waterway that is too thin to be classed as a river. An active, able-bodied person should be able to jump over it if trees along it aren't too thick.|
|waterway||brook||A tiny linear depression in the ground of a width from 10 cm to 1 meter wide. Carryies water at least for some part of the year.|
|| A natural, dry (ephemeral) riverbed that contains water only during times of heavy rain or simply an intermittent stream, in semi-arid areas. Also known as a "Wash" in the deserts of America.
It has been recommended to stop using this tag. Use a combination of waterway=river and intermittent=yes instead.
|| Dry stream bed - negative forms of erosion relief formed by the activity of temporary streams.
Don't use this tag. Use a combination of waterway=stream and intermittent=yes instead.
Man made waterways
|waterway||canal||An artificial open waterway used for transportation, waterpower, or irrigation.(Other languages).|
|waterway||drain||An artificial waterway for carrying storm water or industrial discharge.|
|waterway||ditch||A small to moderate depression created to channel water.|
|waterway||dock||An 'enclosed' area of water used for building or repairing ships.|
|waterway||boatyard||Boat yard – a place for constructing, repairing and storing vessels out of the water.|
Barriers on waterways
|waterway||dam||A wall built across a river or stream to impound the water. A dam normally does not have water flowing over the top of it.|
|waterway||weir||A barrier built across a river, sometimes to divert water for industrial purposes. Water can still flow over the top.|
|waterway||waterfall||A waterfall, use in combination with natural=cliff|
|waterway||lock_gate||To mark the position of gates at each end of a lock. Alternatively, for smaller locks use a single lock=yes node in the middle of the lock.|
Other features on waterways
|waterway||turning_point||A place to turn the driving direction for vessels, where the boats are longer than the river/canal is wide. Use maxlength=* to denote the maximum length of the vessel.|
|waterway||water_point||This tag is for ports/marinas where you can get large amounts of potable water.|
Some additional attributes for waterways
|intermittent||yes||Indicates that the waterway does not have a permanent flow (i.e. is sometimes/often dry).|
|lock||yes||()||A lock is used for moving boats between waterways at two different levels. Can tag either the section of the way between the gates (detailed) or just a single node in the waterway (less detailed).|
|mooring||yes, private, no||A length of bank where boats are explicitly permitted to moor. maxstay=* should be used for timing information.|
|service||transportation, water_power, irrigation||A waterway=canal may have one (or more; separate with semicolons) uses.|
|tunnel||culvert||()||For streams passing under a road in culverts use tunnel=culvert+layer=-1 on the section of stream passing under the road. Don't use either of these tags for streams passing under bridges.|
