North Carolina's River Basins

What is a River Basin?

A river basin is the land that water flows across or under on its way to a river. Just as a bathtub catches all the water that falls within its sides, a river basin sends all the water falling on the surrounding land into a central river and out to an estuary or the sea. The term watershed is used to describe a smaller area of land that drains to a smaller stream, lake or wetland. There can be many smaller watersheds within a river basin. For example, the Neuse river basin contains the Swift Creek watershed, Eno River watershed, Walnut Creek watershed, and the Crabtree Creek watershed - just to name a few! The Neuse river basin flows into the Pamlico Sound, which empties into the Atlantic Ocean.

Do I live in a River Basin?

Yes! Everyone lives in a river basin, even if you don't live near the water. The land that we live on eventually drains to a river or estuary or lake, and our actions on that land affect water quality and quantity far downstream. The topography of each basin determines the area that it drains, and for North Carolina, whether that water flows into the Atlantic Ocean or Gulf of Mexico.

When rain falls on your street, roof or yard, what creek or river will it flow through on its way downhill towards the sea?
When you drain your bathtub or sink, where does the water go?
When you turn on your tap to get a drink of water, where does the water come from?

Just like an artery connects parts of the body to one another, so too does a river thread together the creeks and streams, valleys and hills, lakes and underground springs that share a common network of water. Whatever happens to surface or groundwater in one part of the river basin will find its way to other parts. If water is diverted out of its downward course in one section, other parts will come to "know" of its absence. A river basin comes closer than any other defined area of land, with the exception of an isolated island, to meeting the definition of an ecosystem in which all things, living and non-living, are connected and interdependent.

The Office of EE, in partnership with other DENR divisions including the Division of Water Resources and the Wildlife Resources Commission, has created informative river basin education materials that can be ordered free of charge.
