About this gauge

USGS gauge 03476500 sits on the South Fork Holston and reads everything draining 703 square miles of the South Fork Holston basin. Its datum sits 1,450 feet above sea level NGVD29. Daily flow is on record here from 1951 to 1974, 23 years in all.

Where this gauge sits in the drainage

No gauged site sits above this one on the mainstem, so this is the first published reading on the river. Downstream the next reading comes from Boone Lake at 1,840 square miles, so what passes this gauge is about 38% of the water measured there.

Normal flows here

The South Fork Holston runs a median of 878 cfs at this gauge across 23 years of record. August is the fullest month at a median 1,420 cfs, and March the leanest at 155 cfs. The highest daily mean on record is 7,990 cfs in 1957, and the lowest is 0.5 cfs in 1955.

Medians from the USGS daily-statistics record, 1951 to 1974. 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.
