1. Remember our WATER CYCLE?
Do you remember the awful dance Mr. G does?

2. Where does “run-off” go?
USUALLY TO OUR #1 SOURCE OF FRESHWATER ON EARTH…

3. A lot ends up here!

4. But what about our run-off that doesn’t go underground?

5. RIVER BASINS DRAIN water from highland divides out to the ocean!

6. NC has 17 major rivers that make up 17 basins washing run-off out to the sea!

7. Each of our 17 major river basins are separated by highland ridges called DIVIDES.

8. RIVER BASINS DRAIN water from HIGHLANDS we call DIVIDES.
Where _______ takes control & moves run-off down a big river out to sea.

9. RIVER BASINS DRAIN water from HIGHLANDS we call DIVIDES.
Where gravity takes control & moves run-off down a big river out to sea.

10. And each RIVER BASIN is made of numerous, smaller WATERSHEDS.

11. And each river basin is made of numerous,smaller WATERSHEDS.
little streams, creeks, tributaries that run into a big river

Can you see
the watersheds
in this big river
basin?

13. And each river basin is made of numerous,smaller WATERSHEDS.
Here is a smaller watershed.

Another smaller watershed…

16. How many smaller watersheds are in this river/drainage basin?

17. How many smaller watersheds are in this river/drainage basin?
At least 9, maybe more?

18. How about OUR river basin… the CATAWBA river basin?
Whoa, that’s a lot of watersheds.

19. How about OUR river basin… the CATAWBA river basin?
Whoa, that’s a lot of watersheds.
