What is a watershed?

A watershed is an area of land that collects water whenever it rains or snows. Through gravity, water is channeled into soils, groundwater, creeks, and lakes and drains into larger bodies of water such as rivers. Eventually, the water flows to an ocean. 

We all live in a watershed, and whatever we do to the land will affect water quality downstream.
