The term watershed is used to describe a smaller area of land that drains to a stream, lake or wetland. Many watersheds can reside within a large river basin.
The biggest difference is that water is collected or held in a catchment. A watershed allows the water to drain away. A watershed can be a huge area covering millions of square miles, i.e. the Mississippi River watershed extends from Minnesota to Louisiana, and from Colorado to Ohio.
