I think just "water=pool" is a bit short and potentially misleading with other types of pools (reflecting pool, swimming pool, salt pool, ...).
If you don't need a new tag, I would go for natural=water water=lake (and let the size and position of the feature show that it is a small body of water on a river) After all, it is a kind of lake, only much smaller ;) The various definitions to distiguish lake/pond are quite messy, I do not want to go there. https://en.wikipedia.org/wiki/Pond#Technical_definitions Please also note that in current OSM wiki: water=lake "should be considered default for natural=water, when no water or other descriptive tags are specified". I think it is good enough for the kind of semantics we are trying to achieve in OSM. Otherwise, if I cannot convince you with that alone, at least expand to "stream_pool", like: natural=water water=lake lake=stream_pool or natural=water water=stream_pool -- althio On 11 March 2017 at 10:24, Andrew Harvey <andrew.harv...@gmail.com> wrote: > I'm looking for a tag for "A small and rather deep collection of (usually) > fresh water, as one supplied by a spring, or occurring in the course of a > stream;" https://en.wiktionary.org/wiki/pool#English also like > https://en.wikipedia.org/wiki/Stream_pool. > > They come in all shapes and sizes but are usually part of a stream/creek > where it is deep enough for water to collect there. > > Some photo examples: > > https://www.flickr.com/photos/136319147@N08/32171903253/in/datetaken-public/ > https://www.flickr.com/photos/136319147@N08/32986671125/in/datetaken-public/ > https://www.flickr.com/photos/136319147@N08/25031837975/in/datetaken-public/ > > It's not a lake which is much larger. > > I don't think it's right to use water=pond, which is "man-made in most > cases", and seems to be more commonly used for places in a park where you > find ducks, often with lots of vegetation. > > water=pool seems like the best option.
