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. For the water-covered area of a waterway, see natural=water + water=*.

Key	Value	Element	Comment
Natural watercourses
waterway	river		A river is a wide, natural watercourse that flows from a source to an ocean, sea, lake or another river. For narrow naturally-formed waterways, see `waterway=stream`.
waterway	stream		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		A natural tidal waterway within the coastal marine environment with bi-directional flow of salty water which depends on the tides.
waterway	flowline		Slow-moving flow through a water body.
Artificial waterways
waterway	canal		An artificial open flow waterway used to carry useful water for transportation, waterpower, or irrigation. (Other languages).
waterway	pressurised		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		An artificial free flow waterway used for carrying superfluous water like storm water or industrial discharge, usually lined with concrete, stones or similar.
waterway	ditch		A small artificial free flow waterway used for carrying superfluous water for drainage or irrigation purposes, usually unlined.
waterway	fairway		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`.
waterway	fish_pass		A fish pass, also known as a fish ladder, a fishway or fish steps, is a structure on or around artificial barriers (such as dams and locks) to facilitate diadromous fishes natural migration.
waterway	canoe_pass		A canoe pass is a structure on or around artificial barriers (such as dams and locks) to enable whitewater praticants to go through those barriers
Facilities
waterway	dock		An 'enclosed' area of water which the height of the water can be managed.
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 to control speed and depth. Water can still flow over the top.
waterway	waterfall		A waterfall, use in combination with `natural=cliff`
waterway	rapids		A natural barrier, formed by a fast-flowing, often turbulent, section of the watercourse.
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.
waterway	sluice_gate		A sluice gate is a movable gate to control water flow.
waterway	floodgate		Floodgate regulates the flow of water from a body of water by shutting out, admitting, or releasing water from a reservoir, river, stream, canal.
waterway	debris_screen		Debris screen (or trash rack (US) prevents water-borne debris (such as logs, boats, etc.) from entering the intake of a water mill, pumping station or water conveyance.
waterway	security_lock		Flood barrier
waterway	check_dam		Flood and debris barrier
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		A place to fill fresh water holding tanks of a boat.
waterway	fuel		A place to get fuel for boats.
Some additional attributes for waterways
intermittent	yes		Indicates that the waterway is sometimes dry and sometimes contains water.
seasonal	yes, spring, summer, autumn, winter, wet_season, dry_season		Indicates that a waterway has a seasonal (yearly cyclic) flow, usually flowing continuously for at least some part of the year.
destination	name		Name of the body of water the linear feature flows into.
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.
usage	See the key for details		Possible uses of the waterway. Use semicolons to separate.
tunnel	culvert	()	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.
tunnel	flooded		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=*`.
bridge	aqueduct		A bridge which conveys an artificial waterway over a road, valley, or another waterway.
waterway	user defined		All commonly used values according to Taginfo
