Transylania counties. In North Carolina, its easternmost tributaries — 

 the Toxaway, Horsepasture, Thompson, and Whitewater rivers — flow 

 south as independent streams, entering Lake Jocassee and the Keowee 

 River system of the Savannah basin not far into South Carolina. West 

 of these rivers, the Chatooga River and several even more western 

 tributaries of that river head in Macon County and flow independently 

 south. The Chatooga River forms part of the upper boundary between 

 Rabun County, Georgia, and Oconee County, South Carolina. The 

 Tallulah River, which rises in the southeastern corner of Clay County 

 on the slopes of Standing Indian Mountin, flows south into Towns 

 and Rabun counties, Georgia, where it joins the Tugaloo River of 

 the upper Savannah system. 



The crayfish fauna of the Savannah River basin in North Carolina 

 consists of the endemic C. reburrus (currently known in this system 

 only from the floodplain of the Horsepasture River in Jackson County), 

 C. b. bartonii, C. asperimanus, and Cambarus sp. (Hobbs and Peters 

 1977:38). The type locality of C. reburrus is in the Savannah basin 

 (see the preceding account for this species). Little is known of 

 the crayfish fauna of the Tallulah River in North Carolina, but 

 C. asperimanus and C. b. bartonii undoubtedly occur there. 



Broad River — This system rises in the west as headwater streams 

 in southern and eastern Henderson, western Polk, and eastern 

 Buncombe counties, and in the north in southern McDowell and 

 northern Rutherford and Cleveland counties. A western tributary, the 

 North Pacolet River, heads in southern Polk and Henderson counties, 

 and flows independently into the Pacolet River of South Carolina. 

 The Pacolet and Broad rivers merge at the juncture of Cherokee, 

 Union, and Chester counties, South Carolina. Eastern tributaries 

 head in eastern Cleveland and western Lincoln and Gaston counties, 

 flow independently into South Carolina, then soon join the Broad 

 River at the line between Cherokee and York counties. The Broad 

 flows through the eastern foothills and western Piedmont of North 

 Carolina, across South Carolina, and merges with the Saluda River at 

 Columbia to form the Congaree River. The Congaree joins the Wateree 

 River (continuation of the Catawba River), and the Wateree flows 

 into the Santee system via Lake Marion. 



The crayfish fauna of the Broad River basin in North Carolina 

 consists of C. b. bartonii (the eastern and southern limits of its 

 range here are unclear, but it is known from Cane Creek, McDowell 

 County, and Green River, Henderson County), C. sp. A (Hobbs and 

 Peters 1977:52), C. asperimanus (in southeastern McDowell and 

 northeastern Cleveland counties), and C. sp. C (which is probably
