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.
