What's a watershed? |
| Watersheds
are simply the land area that water flows across or under on its way to
a stream, river, lake, or ocean. See a watershed
graphic. How do watersheds work? The landscape is made up of many interconnected watersheds or basins. Within each watershed, all water runs to the lowest point - a stream, river, lake or ocean. A watershed is sort of like a basin or bathtub where all water drains to a certain place. On its way through the watershed, water travels over the surface of the land whether it is farm fields, forestland, suburban lawns, or city streets. To watch this happen, view this watershed movie. Water can also travel under the land as it soaks into the ground and travels as groundwater. |
