The Dan River is the major southern tributary to the Roanoke River. It 

 originates on the Blue Ridge uplands in south central Virginia and, after a course 

 of 59 rkm, enters North Carolina in northwest Stokes County; it crosses the state 

 line five more times before joining the Roanoke River at Kerr Reservoir in Hal- 

 ifax County, Virginia (Fig. 3). The 140 rkm North Carolina portion drains 

 approximately 4,410 km 2 of the state. River elevation drops from 366 m at the 

 point where it first enters North Carolina to 140 m where it first exits North Car- 

 olina in northeast Rockingham County (from U.S. Geological Survey 7.5 minute 

 series topographic maps).
