What is a watershed?

A watershed is typically defined as the area of land where all precipitation drains to a common water body, such as a river or lake. Watersheds are not made of water, but of land. This means that the boundaries of a watershed are determined by the shape of the land that surrounds them. Water runs downstream, so buttes and ranges often form the boundaries of watersheds.
