A small river or stream is not called a river basin. A river basin is a portion of land drained by a river and it's tributaries. It encompasses all of the land surface dissected and drained by streams and creeks that flow downhill into one another, and eventually into one river.

A small stream in a river is called a current.
Are you crazy? A stream or a small river is called a TRIBUTARY.
A drainage basin is simply an area between two ridges from which water drains as a stream or river. A small creek has its own drainage basin. The drainage basin of the Mississippi River includes everything between the Rocky Mountains and the Adirondacks.
Every river is part of a larger river system which includes the river and any tributaries that branch off of it.
