About this gauge

USGS gauge 03432100 sits on the Harpeth River and reads everything draining 67 square miles of the Harpeth basin. Daily flow is on record here from 2007 to 2012, 6 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 Harpeth River at Mile 90.5 near Franklin, TN at 183 square miles, so what passes this gauge is about 36% of the water measured there. Water passing here goes on to Harpeth River at Franklin, TN, Harpeth River below Franklin, TN and Harpeth River at Mile 81.33 near Berrys Chapel, TN.

Normal flows here

The Harpeth River runs a median of 17 cfs at this gauge across 6 years of record. March is the fullest month at a median 103 cfs, and August the leanest at 0.8 cfs. The highest daily mean on record is 3,450 cfs in 2010, and the lowest is 0.0 cfs in 2012.

Medians from the USGS daily-statistics record, 2007 to 2012. 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.
