No matter where you go, you are always in a watershed. A watershed is an area within which water from rain and springs drains into a specific place such as a stream or lake. The water you drink and swim in is part of your watershed. To figure out where your watershed is all you need to do is connect all the highest points of land around you. You can think of a watershed as a bathtub. Any water that hits the walls or sides of the bathtub collects in the bottom of the tub. If water is splashed outside the tub, it falls outside the bathtub's watershed. This is similar to what happens in a real watershed. If rain falls anywhere in the watershed, it will flow downhill until it reaches a stream, river, pond or other type of water body. The following activities will introduce the concept of watersheds and how to locate your watershed.
