Stream, river, lake, pond, sea, ocean are clear enough to be understood by an occasional mapper and correspond to existing tags. Instead, to undestand what waterbody would mean, mappers and users should read the wiki explanation.

The distinctions given in the wiki between a stream and a river, and
between a pond and a lake, are far from objective. Just because the
words are familiar does not in itself guarantee good-quality
(objectively and verifiably correct) tagging. 

Apparently there is a scientific distinction between a pond and a lake,
based on whether sunlight reaches the bottom. I also found a reference
to a river/stream distinction based on stream order.
