I don't like this, as I feel pond is "more commonly used for places in
a park where you find ducks, often with lots of vegetation", and the
water would cover a larger area, and not be flowing as much as a pool.

That was the plan, but I wanted to see what others thought and see if
there was a consensus first.

I agree, a lake and this kind of stream pool are fundamentally
different. natural=water is the common element already.

My view is that a river has enough flow and is wide enough tag as an
area with waterway=riverbank or water=river. So you wouldn't really
get these pools on a river.

A stream on the otherhand might only be able to be tagged as a linear
way in most sections as the water doesn't collect, except for a pool
along the lake. (ie. a pool / stream pool). Further the pool usually
isn't flowing in the same way as the creek, so I don't think it makes
sense to tag as a stream area (a stream area, would be mostly rock,
not water).

I'm not fussed with water=stream_pool or water=pool. I agree with
althio that water=stream_pool is more explicit, and water=pool could
be confused with a reflecting pool, swimming pool,
