North Carolina Reserve
The Currituck Banks Component
The Currituck Banks site is an excellent example of an undisturbed barrier island and low-salinity estuarine system. The site lies in the northeastern corner of North Carolina, 10 miles south of the Virginia border and three-quarters of a mile north of the village of Corolla, in Currituck County. Bounded by Currituck Sound and the Atlantic Ocean, the site encompasses 954 acres. The Nature Conservancy and the U.S. Fish and Wildlife Service own neighboring tracts.
Watershed
The Albermarle Sound is formed by the union of the Roanoke and Chowan rivers. They drain 8,000 and 4,800 square miles respectively. Due to its distance from the ocean, it is generally fresh for most of its length. As freshwater flow reduced due to consecutive years of drought, the salt content has risen. The Pasquotank, Alligator and Scuppernog rivers also empty into the sound before it meets the Currituck Sound.
