Ponds - What is a Pond?

A pond is a small area of still, fresh water. It is different from a river or a stream because it does not have moving water and it differs from a lake because it has a small area and is no more than around 1.8m deep. Some ponds are formed naturally, filled either by an underwater spring, or by rainwater – sometimes known as ‘dewponds’; other ponds are artificially made.
