headwater
Stream's starting point
The headwaters of a river or stream are the small tributaries and springs near its source, where it begins: We hiked to the headwaters of the Mississippi.
The term appears almost exclusively in the plural, though headwater works as a modifier: headwater streams, headwater region.
