Man made body of stored water. May be covered or uncovered.
There was considerable confusion whether landuse=reservoir is deprecated, but it turned out to be not deprecated and landuse=reservoir is used much wider than "new" way natural=water + water=reservoir.
It may be a good idea to tag the actual water body with natural=water + water=reservoir in addition or instead of landuse=reservoir. See also the approved water details proposal and pointers to discussion on talk page.
Currently most renderers will interpret and draw landuse=reservoir as a visible open water area.
How to tag
Begin by placing a node or a closed way on the map, and tagging it with
|landuse=reservoir||A man-made body of stored water.|
It sometimes makes sense to add the following tags:
|name=*||The name of the reservoir, if known.|
|covered=yes/no||Whether the reservoir is covered, typically buried underground.|
|natural=water + water=reservoir||Can be added if the reservoir is also a body of open water.|
Osmarender has different rendering rules using the key reservoir_type=*:
- approved and active: water details proposal which obsoletes this tag
- in mail discussions the wish was formulated to create a tagging scheme covering areas and objects related to water reservoirs (a superset of the current definition). Although it might seem logical to use landuse=reservoir for such purpose this would conflict with the current widely used definitions and another tagging scheme should be proposed instead.
- landuse=pond (deprecated)
