Most lakes have one or more feeding and draining rivers. Many lakes, such as Lake Constance in the Rhine, are considered to be part of a river. However, such a river is not a criterion for a lake; drainage may also be by evaporation and the water supply may also come directly from precipitation.
Lakes that have no drainage, such as the Caspian Sea, the Dead Sea and the Great Salt Lake, often contain salt water. For this reason, they are sometimes considered to be sea rather than lake. The first two are even below sea level and therefore cannot have natural drainage.
The Dutch IJsselmeer is an exception. It lies below sea level. The drainage via the Afsluitdijk is artificial.
A lake is a lake that has been artificially created by peat extraction or the extraction of minerals such as sand and gravel. This often leaves behind deep pools, up to thirty metres deep.
Water surfaces in gardens and parks are often called ponds.
A fen is a naturally formed heath lake.
A reservoir is an artificial lake created by damming a river.
