About this gauge

USGS gauge 02081000 sits on the Roanoke River and reads everything draining 8,671 square miles of the Lower Roanoke basin. Its datum sits 5 feet above sea level NAVD88. Daily flow is on record here from 1941 to 1979, 18 years in all.

Where this gauge sits in the drainage

Lake Gaston (Little River Channel) near Henrico, NC sits immediately upstream, so dam releases rather than rainfall set the flow here. Four gauged sites sit upstream of here. The closest is Roanoke River at Halifax, NC, reading 8,450 square miles. This gauge adds the 221 square miles that drain in between. Downstream the next reading comes from Roanoke River near Oak City, NC at 8,810 square miles, so what passes this gauge is about 98% of the water measured there. Water passing here goes on to Roanoke River at Hamilton, NC.

Normal flows here

The Roanoke River runs a median of 5,750 cfs at this gauge across 18 years of record. March is the fullest month at a median 10,100 cfs, and September the leanest at 3,270 cfs. The highest daily mean on record is 115,000 cfs in 1945, and the lowest is 750 cfs in 1953.

Medians from the USGS daily-statistics record, 1941 to 1979. A month at 100% is running at its own long-term median. USGS stopped publishing a daily flow record at this gauge, so these are historical norms, not a baseline for current readings.
