A watershed is the area where all of the water that is on or under the land drains to the same place. In other words, it is where the water from the higher elevations settle in lower elevations. Watersheds come in all shapes and sizes. They cross county, state, and national boundaries. No matter where you are, you’re in a watershed, including your home!
