What is a Watershed?

A watershed is an area of land that drains all the streams and rainfall to a common waterway. The word watershed is sometimes used interchangeably with drainage basin or catchment. A watershed consists of surface water--lakes, streams, reservoirs, and wetlands--and all the underlying ground water. Larger watersheds contain many smaller watersheds. It all depends on the outflow point; all of the land that drains water to the outflow point is the watershed for that outflow location.
