20.Watersheds and River Basins

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 will 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 will define key River Basin Vocabulary

What percentage of the world’s fresh water is ice and what are two reason we can’t access this

source of water?

Water ~ 8th Grade Science

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

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

an area of land that drains water to the lowest point—a river, stream, lake, or ocean

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

Durham has 5 main Watersheds:1.Lake Michie*

* (not pictured)2.Little River3.Eno River4.Falls Lake5.Jordan Lake

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

A group of interconnected watersheds form 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 destinationis an estuary or ocean.

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.

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

North Carolina River Basins

NC is made of 17 river basins5 will flow into the Mississippi River BasinThe other 12 will flow into the Atlantic Ocean

11 originate in NCOnly 4 are entirely contained within NC:

Cape Fear, Neuse, White Oak, and Tar-Pamlico

Durham

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

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
