The waterway key is used to describe rivers, streams and boat-yards. Some 'water' related features use other tags, including

Or with the new tagging: natural=water + water=reservoir

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 seasonal=*. If intermittent (irregular) then use the tag intermittent=*.

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. See water=river for alternative tagging.
waterway stream Way 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 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 waterway used for transportation, waterpower, or irrigation.(Other languages).

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 This tag is for ports/marinas where you can get large amounts of potable water. Deprecated. See wiki page.

Some additional attributes for waterways

intermittent yes Way Indicates that the waterway does not have a permanent flow (i.e. is sometimes/often dry).
seasonal yes, spring, summer, autumn, winter, wet_season, dry_season Way Indicates that a waterway has a seasonal (yearly cyclic) flow.

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).
mooring yes, private, no Way A length of bank where boats are explicitly permitted to moor. maxstay=* should be used for timing information.

service transportation, water_power, irrigation Way A waterway=canal may have one (or more; separate with semicolons) uses.
tunnel culvert Way (Node) 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.
waterway user defined Node Way All commonly used values according to Taginfo
