Source (river or stream)
From Simple English Wikipedia, the free encyclopedia
The source of a river or stream is the original point from which the river flows.
The source of a river or stream may be a lake, a marsh, a spring or a glacier.
The furthest stream is called the Headstreams. The source is the farthest point of the river stream from its estuary or its confluence with another river or stream.
Where a river is fed by more than one source, it is usual to regard the highest as its source.
