How does the watershed affect the water body?
A watershed – the land area that drains to a stream, lake or river – affects the water quality in the water body that it surrounds. Healthy watersheds not only help protect water quality, but also provide greater benefits than degraded watersheds to the people and wildlife that live there.
What watershed is North Carolina?
In North Carolina, the five western basins drain to the Gulf of Mexico (Hiwassee, Little Tennessee, French Broad, Watauga and New). The other 12 basins flow to the Atlantic Ocean. Only four basins are contained entirely within the state (Cape Fear, Neuse, White Oak and Tar-Pamlico).
What is the major difference between a watershed and river basin in NC?
A river basin consists of all the waters (tributaries, lakes, reservoirs ground water etc.) that flows (drains) down towards the river. Watersheds are smaller land areas and located within a river basin that include; creeks, streams, lakes, reservoirs, groundwater, aquifers, springs and sections of a river.
Where does all the water run to within each watershed?
A watershed is the area of land where all of the water that drains off of it goes into the same place—a river, stream or lake. The smallest watersheds are the drainage areas for small streams and lakes. Think about your local creek or river.
Can a watershed be fed by groundwater?
The boundaries of a surface watershed and groundwater recharge area can, but do not always, coincide. Lakes that appear to have no major inlet are often fed by groundwater. Sometimes humans withdraw too much water from an aquifer, resulting in serious problems.
How are watershed scores calculated in NC?
The selected factors contributing to watershed characteristics ratings are average annual precipitation, land-surface slope, land cover, land use, and ground-water contribution. For surface-water systems, the higher the inherent vulnerability of a watershed, the higher the rating applied on a scale of 10 to 100.
What is the biggest watershed in NC?

Why is it called a watershed?
But, the word was originally a geographical term describing the area from which water sources drain into a single river or a ridge, like that formed by a chain of mountains, which sends water to two different rivers on either side. From that, watershed came to mean a turning point or dividing line in life.
What are 3 key features to a watershed?
A watershed is dynamic and three-dimensional. It includes precipitation, the network of surface streams and the groundwater stored in underground aquifers.
How many watersheds are there in North Carolina?
