The lands water flows across or under on its way to a stream, river or lake. The landscape is made up of many interconnected basins, or watersheds. On its way, water travels over the surface and across farm fields, forest land, suburban lawns and city streets or its seeps into the soil and travels as groundwater. Large watersheds like the ones for the Mississippi River, Columbia River and Chesapeake Bay are made up of many smaller watersheds across several states. Not at all.
Watersheds come in many different shapes and sizes and have many different features.
Watersheds can have hills or mountains or be neatly flat. They can have farmland, rangeland, small towns and big cities. Parts of your watershed can be so rough, rocky or marshy that they're suited only for certain trees, plants, and wildlife. Everyone lives in a watershed. You and everyone in your watershed are part of the watershed community.
