About this gauge

USGS gauge 02203950 sits on Snapfinger Creek and reads everything draining 13 square miles of the Upper Ocmulgee basin. Its datum sits 845 feet above sea level NAVD88. Daily flow is on record here from 2010 to 2024, 14 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 Snapfinger Creek at Thompson Mill Rd near Lithonia, GA at 33 square miles, so what passes this gauge is about 40% of the water measured there. Water passing here goes on to South River at Klondike Road, near Lithonia, GA and South River at GA 81, at Snapping Shoals, GA.

Normal flows here

Snapfinger Creek runs a median of 8.8 cfs at this gauge across 14 years of record. February is the fullest month at a median 15 cfs, and October the leanest at 4.7 cfs. The highest daily mean on record is 836 cfs in 2016, and the lowest is 0.8 cfs in 2012.

Medians from the USGS daily-statistics record, 2010 to 2024. 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.

Flood stages and record crests

Snapfinger Creek reaches flood stage at this gauge at 12 feet. NWS starts watching it at 10 feet. The highest crest on record is 18 feet, in September 2009.
