Where is the source of the river?

The source of the river is called a different kind of reservoir or the place from which it flows, that is, it originates. These can be springs, swamps, lakes or high-altitude glaciers. On a geographical map, the source of the river is shown by a conventional point. It often happens that the beginning of large rivers is considered to be the confluence of two rivers bearing different names. For example, the Ob River – from the confluence of Biya and Katun.
