What is a watershed?
A watershed is the drainage basin of a river or stream. All the precipitation, whether rain or snow, that falls in the basin eventually drains downstream and collects in larger and larger watercourses. Tiny brooks join to form streams, these combine to become creeks and these drain together into rivers. A watershed is actually an area of land from which water drains into a single river. Water ties this tract of land together.
