This feature has been labeled as deprecated. The recommended replacement is: natural=water + water=reservoir.|
The reason is documented in Deprecated features. You are still free to continue to use or interpret this tag as you see fit since OpenStreetMap does not have “banned features”. Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the Automated Edits code of conduct. Each of these changes would be reverted.
Man made body of stored water. May be covered or uncovered. Usually formed by a dam over a natural water course, water then backs up into a natural valley or depression.
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.
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.
