1. Watersheds and Drainage Basins
Where does our water flow from and into?

2. What is a watershed?
A watershed is a landform defined by highpoints and ridgelines that descend into lower elevations.
A watershed carries water “shed” from the land after rain falls and snow melts.
The water of the area flows across or through on its way to a particular water body, such as a stream, river, wetland or coast of a drainage basin.

5. What is a Drainage Basin?
A drainage basin is an extent or area of land that drains all precipitation (rain, melting snow, ice) received as runoff from watershed.
The runoff converges to a single point, usually the exit of the basin, where the waters join another body of water, such as a river, lake, wetland, sea, or ocean.
