Waterway

This is used to described different types of waterways. When mapping the way of a river, stream, drain, canal, etc. these need to be aligned in the direction of the water flow. See the page titled Waterways for an introduction on its usage.

Natural watercourses

waterway river way For narrow rivers which will be rendered as a line. For larger rivers see also waterway=riverbank (Other languages).

waterway riverbank area Used for larger rivers in addition to waterway=river, to define an area between the opposite riverbanks. Also see water=river with natural=water.

waterway stream way A naturally-formed waterway that is too narrow to be classed as a river. An active, able-bodied person should be able to jump over it.

waterway tidal_channel way A natural tidal waterway within the coastal marine environment with bi-directional flow of salty water which depends on the tides.

waterway wadi way 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. For intermittent waterways use waterway=river/waterway=stream + intermittent=yes. For valleys natural=valley.

waterway drystream way Dry stream bed - negative forms of erosion relief formed by the activity of temporary streams.
Don't use this tag. For intermittent waterways use waterway=stream + intermittent=yes. For valleys use natural=valley.

Man made waterways

waterway canal way An artificial open flow waterway used to carry useful water for transportation, waterpower, or irrigation. (Other languages).
Grand Union Canal.jpg
waterway pressurised way A waterway where water is flowing in a fully enclosed conduit and subject to pressure; this includes gravity-driven penstocks and siphons and pump-driven pipelines, for example.

waterway drain way An artificial free flow waterway used for carrying superfluous water like storm water or industrial discharge, usually lined with concrete, stones or similar.
Example Drain.jpg
waterway ditch way An small artificial free flow waterway used for carrying superfluous water for drainage purposes, usually unlined.

waterway fairway way A navigable route in a lake or sea marked by buoys. The navigable area marked by the buoys can be mapped with seamark:type=fairway.

Facilities

waterway dock node area An 'enclosed' area of water used for building or repairing ships.

waterway boatyard nodearea Boat yard – a place for constructing, repairing and storing vessels out of the water.

Barriers on waterways

waterway dam way area 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.
Amagase Dam.jpg
waterway weir node way A barrier built across a river to control speed and depth. Water can still flow over the top.
Alifakovac Miljacka.jpg
waterway waterfall node A waterfall, use in combination with natural=cliff

waterway lock_gate node 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 node 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 node A place to fill fresh water holding tanks of a boat.
waterway fuel node area A place to get fuel for boats.

Some additional attributes for waterways

intermittent yes way Indicates that the waterway is sometimes dry and sometimes contains water.
Rendering-intermittent-river-mapnik.png
seasonal yes, spring, summer, autumn, winter, wet_season, dry_season way Indicates that a waterway has a seasonal (yearly cyclic) flow, usually flowing continuously for at least some part of the year.

destination name way Name of the body of water the linear feature flows into.
lock yes way (node) 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).
JesusGreenLock-Cambridge.jpg
mooring yes, private, no way A length of bank where boats are explicitly permitted to moor. maxstay=* should be used for timing information.

usage transmission, irrigation, headrace, tailrace, penstock way A waterway=canal may have one (or more; separate with semicolons) uses.
tunnel culvert way (node) A short tunnel usually installed under roads, railways or building. Its size doesn't allow human to get inside and is as narrow as the structure is supposed to go under. 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.
Culvert.jpg
tunnel flooded way A long (> 100 m) tunnel where flowing water or other fluid prevent humans from safely walking inside despite its appropriate diameter or size. Water inside can be pressurised or not, used in combination with any waterway=* linear value.
Waterway free flow tunnel.png
bridge aqueduct way A bridge which conveys an artificial waterway over a road, valley or another waterway.

waterway user defined node way All commonly used values according to Taginfo
