The term watershed is used to describe a smaller area of land that drains to a smaller stream, lake or wetland.

What is catchment area and water flow?

A catchment is an area of land, usually surrounded by mountains or hills, over which water flows and is collected. Within a catchment, water runs by gravity to the lowest point. The water is called surface runoff if it stays on the top of the land or groundwater flow if it soaks into the ground.

How do I identify a watershed?

At each point on the stream the land slopes up on each side to some high point then down into another watershed. If you were to join all of these high points around the stream you would have the watershed boundary. (High points are generally hill tops, ridge lines, or saddles).
