[Tagging] Waterway direction

[John F. Eldredge]

If a body of water that is not navigable is not a waterway, does this mean that any river that contains a waterfall is not a waterway?  What about a stream or river that has portions that are too shallow to be navigable, or where the current is too rapid?  What if it is navigable for only part of the year?

The wiki page for the waterway tag does not say that a body of water must be navigable in order to be classified as a waterway.

Because it's not navigable, therefore it's not a waterway.  And
because the wiki says to use tunnel=culvert, not waterway=culvert.
