The source or headwaters of a river or stream is the furthest place in that river or stream from its estuary or confluence with another river, as measured along the course of the river.ometimes the source of the most remote tributary may be in an area that is more marsh-like, in which the uppermost or most remote section of the marsh would be the true source. For example, the source of the River Tees is marshland. The furthest stream is also often called the headstream.
