The Waccamaw silverside is an imperiled fish endemic (found nowhere else in the world) to the waters of Lake Waccamaw, a Carolina bay lake in Columbus County, NC.
The Waccamaw Silverside is a small, thin fish, almost transparent with a silver lateral stripe. The eyes are large for its size and its jaw is angled upward.
Distribution by County: Waccamaw River Basin: Columbus Co. (Lake Waccamaw and Big Creek). NOTE: All headwater areas that flow into these occupied habitats should receive special management.
This species is found only in the waters associated with Lake Waccamaw, Columbus County, North Carolina. This is a natural lake fed by acidic swamp waters; however, as a result of exposed limestone formations, the pH of the lake itself is near neutral. The Waccamaw Silverside can be found in schools near the surface throughout this shallow lake (Shute 1997).
The Waccamaw Silverside spawns through April and June, and their entire life cycle is typically completed in less than 2 years (Shute 1997).
