What is the major difference between lakes and ponds?

Ponds have plants growing in them while lakes do not.

Lakes are temporary while ponds are permanent.

Light reaches the bottom of a pond, but does not reach the bottom of a lake.

Ponds are man made while lakes are natural

Both lakes and ponds are standing or slow-moving bodies of water. There are no official or scientific differences between lakes and ponds. Lakes are larger than ponds, but size is relative. What would be considered a pond in one region might be considered a lake in another.
