Within a watershed, all the water beneath the soil (groundwater) and rain water or snow are drained into the same place such as a stream, lake, or wetland. These bodies of water supply us with the water we drink, water for agriculture and manufacturing, and opportunities for recreational activities like canoeing and fishing. They also provide habitats for numerous plants and animals. The National Park Service monitors and manages the health of watersheds.
