I agree about the tag water=pool. Potentially very misleading.

Stream_pool seems okay, or perhaps waterway_pool to avoid a possible
semantic conflict when applying the tag to rivers. Are there plans to add
"riffles" as well? A riffle is, in American English at least, a fisherman's
term for a shallower place in a river or stream where the water runs faster
than normal. A riffle is akin to a rapid, only much smaller and slower
running.  Folks fish the pools and riffles for trout, salmon, etc.
