EQ: Where is Earth’s water located? What percentage of water is available for our use?

1. EQ: Where is Earth’s water located? What percentage of water is available for our use? • LT: I can explain the processes by which water moves through the water cycle. • POU: I can create a relief map to determine where and how water flows through a watershed. . I will differentiate between Watersheds & River Basins. I will identify major river basins in NC. I can define key River Basin Vocabulary

3. Watersheds and River Basins 12 Water ~ 8th Grade Science

4. Surface Water • We know that precipitation (rain, snow, sleet and hail) will soak into the ground or it runs downhill into surface water. • What is surface water? • Water found on the surface of the Earth such as rivers, lakes, streams or ocean

5. Fresh Surface Water Locations— Rivers, Streams, and Lakes • What is a river? • A large channel along which water is continually flowing down a slope—made of many streams that come together (tributaries) • What are tributaries? • streams and smaller rivers that feed into a main/large river • What is a stream? • A small channel along which water is continually flowing down a slope—made of small gullies • What is a lake? • A body of water of considerable size contained on a body of land

6. What is a watershed? an area of land that drains water to the lowest point—a river, stream, lake, or ocean

7. Everyone lives, works or plays in a watershed. Watersheds drain water to the lowest point.  In the diagram below, the land within the white line is the watershed that drains into the tributaries that will eventually flow larger river and then on to the ocean

9. Durham has 5 main • Watersheds: • Lake Michie* • * (not pictured) • Little River • Eno River • Falls Lake • Jordan Lake

10. In this image you can see all the tributaries that make up the different watersheds.

11. A group of interconnected watersheds form a river basin.

12. What is a River Basin? Encompasses all land surface drained by tributaries (streams and creeks) that flow downhill eventually into one large river. • A river basin’s final destination is an estuary or ocean.

13. River Basin Analogy…. A bathtub catches all water falling within its’ sides, a River basin sends all the water falling on surrounding land into a central river and out to an estuary or ocean.

14. Fresh Water Locations—River Basins and Watersheds • Durham County is located mainly in the Neuse River Basin • The largest river basin in NC is the Cape Fear River Basin • Cape Fear and Neuse River Basins are made of many small watersheds

15. North Carolina River Basins Durham NC is made of 17 river basins 5 will flow into the Mississippi River Basin The other 12 will flow into the Atlantic Ocean 11 originate in NC Only 4 are entirely contained within NC: Cape Fear, Neuse, White Oak, and Tar-Pamlico

16. Some river basins will become watersheds to another LARGER river basin such as the Mississippi River Basin. • In NC the New, Watauga, French Broad, Little Tennessee, Hiwassee all flow into the Ohio River Basin and then to the even larger Mississippi Basin

17. Mississippi River Basin’s watersheds are large areas.

18. Mississippi River Basin

19. River Basin Vocab 13 Tributaries: streams and smaller rivers that feed into a main/large river Watershed: an area of land that drains water to the lowest point—a river, stream, lake, or ocean. Several Watersheds make up a River Basin River Basin: an area of land that drains water into a large river
