It's possible to make the distinction.  It's not clear-cut.  There are
definitions which are not entirely compatible with each other, but they
have more similarities than differences.  Edge cases are hard.

See, for example:


Most of them agree that lakes have aphotic zones (deep areas that receive
no sunlight, preventing plants from growing there).  But wave height,
of temperature, and area of water may play a part.  And, of course, there's
the locals call it.

Renderers will probably treat them identically  A limnologist would find the
distinction useful.

There is also a distinction between pools and ponds.  However, since pools
are supplied by a spring or a stream, most can be distinguished by other
water=* occurring in conjunction with them (a lot of the ponds I've mapped
are actually pools).
