Curly Brunette Girl In The Nature At The Pond With A Big Tree

Regional differences include the use of the word pond in New England, and Maine in particular, for relatively large water bodies. For example a Great Pond in Maine is considered to be at least 10 acres (41,240 m²) in area.
In areas which were covered by glaciers in the past, some ponds were created when the glaciers retreated. These ponds are known as kettle ponds. Walden Pond in Concord, Massachusetts, is a well known example. Kettle ponds are usually quite deep and clean because they are fed by underground aquifers rather than surface streams.
The term is also used for temporary accumulation of water from surface runoff (ponded water).
There are various regional names for naturally occurring ponds. In Scotland, one of the terms is lochan, which may also apply to a large body of water such as a lake.
