When does a body of water go from being called a pond to being called a lake? Does the acreage determine it?

Answer 1

"There are no official definitions for generic terms as applied to geographic names." " The difference between lake and pond is an example." "The only area of general agreement is that perceptibly, a pond is smaller than a lake, but even this is not always true."

"The Pond
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 man-made."

"A pond is a body of water smaller than a lake. However the difference between a pond and a lake is subjective. Pond usually describes small bodies of water, generally smaller than one would require a boat to cross. Another definition is that a pond is a body of water where even its deepest areas are reached by sunlight or where a human can walk across the entire body of water without being underneath. In some dialects of English, pond normally refers to small artificially created bodies of water".

Lake
"A lake is a body of water surrounded by land. The majority of lakes are fresh water, and most lie in the Northern Hemisphere at higher latitudes."

Answer 2

a pond is man-made, lake is formed when cut off from a river

Answer 3

i think lakes are fed by a source, like a river... ponds are just big holes filled with water.
