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
