No matter where you live or play, you’re in a watershed! So what is it and how does it work? A watershed is an area of land where all the water (surface and groundwater) flows to the lowest point – usually a stream, lake or river.
Imagine your bathtub is a watershed and the drain is a river. Any water that falls inside the tub (watershed) will eventually go down the drain (river) carrying dirt and soap with it. The high sides of the tub (like mountains and hills) keep the water from ending up on the floor (or in other watersheds).
