Roanoke River Basin
Transcript of Roanoke River Basin
What is a River Basin?
The Roanoke River Basin
A river basin is the land that water flows across or under on its way to a river. It can be compared to a bathtub. A bathtub catches the water that falls within its sides. Likewise, a river basin catches all the water that falls on the surrounding land and sends it through streams and creeks into a central river and eventually to an estuary or the sea.
There are 17 river basins in North Carolina.
We live in the Catawba River Basin.

Facts about the
Roanoke River Basin
Where does the
Roanoke River Basin
start and end up?
River Basins have both natural and man-made components.
The Roanoke River carries more water than any other North Carolina river.
This river basin has the widest floodplain – up to 5 miles in some places.
How many are in North Carolina?
What is our Local River Basin?
Are river basins natural or man-made ?
This river basin has places I have never been but would like to visit:
All or portions of 17 North Carolina
counties lie between the start to finish.
Over 60% of the Roanoke Basin lies within the state of Virginia.
Starts: Blue Ridge Mountains of southwestern Virginia
Ends: The Albemarle Sound, part of the second largest estuary system in the United States (Albemarle-Pamlico)
The water flows from mountainous areas,into the Piedmont, as it makes it way to the Coastal Plains.
Over half of the land in the river basin is forested.
What does the area around the River Basin look like?
Over 200 bird species have been identified in this ecosystem.
Native Americans and early settlers called it the “river of death” because the floods in the spring killed many people.
The Roanoke River creates one of the largest swamp ecosystems in the eastern United States
The area is home to black bear, river otter, white-tail deer, bobcat, racoons, beaver and mink.
It is the largest intact
bottomland hardwood swamp forest
east of the Mississippi.
Mistletoe and Spanish moss hang from century-old cypress trees and massive tupelos.
The 33,000-acre Roanoke River National Wildlife Refuge has a positive impact on the river basin and surrounding communities.
The Wetlands are important to the Roanoke River Basin because
they enhance water quality
provide flood control
Protect the wildlife
Organisms at the bottom of the food
chain thrive in the wetlands . Many species
of fish, amphibians, shellfish, and insects eat
Most birds and mammals rely on the wetlands for food, water, and shelter, especially during migration and breeding.
Man's destruction of aquatic habitat is the largest issue in the water quality of the basin.
Agriculture, Forestry, and Construction are the main areas negatively impacting the basin.
A recent issue has been the Coal Ash Spill at the Dan River in the Roanoke River Basin. Jamie Krizer, a spokesman for the NC Department of Environment and Natural Resources says, "It's unclear what that could mean for wildlife in the area. It's certainly cause for concern for the long-term impacts of this coal ash spill on the health of the Dan River."
"Environmental advocates warn that the damage could be significant, potentially harming fish in the river and impacting the food chain." (Shoichet)
There are 11 major reservoirs along the North Carolina portion of the Roanoke River; most are in the upper basin on tributaries of the Dan and Roanoke Rivers.
Humans still continue to pollute our waterways through industry and personal refuse.
Smith Mountain Lake (to the north) is one of the state’s top striped bass fisheries.
Kerr Reservoir (to the south) offers 49,000 acres of
fishing, boating and camping.
The River Basin also provides water to municipalities in the basin, but droughts have caused major water issues in these areas and conservation plans have been put into action.

Here you can catch striped bass,
large mouth bass, black crappie,
lunker catfish, gar and bowfin.
Do you like to fish???
that make a positive impact are: .
A wetland is the area between dry land and open water. It is sometimes covered with a shallow layer of water, but there are also wetlands which can be dry for part of the year. The plants and animals which live there have adapted to this environment.
