About this gauge
USGS gauge 02334885 sits on Suwanee Creek and reads everything draining 47 square miles of the Upper Chattahoochee basin. Its datum sits 910 feet above sea level NAVD88. Daily flow is on record here from 1985 to 2024, 40 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 Chattahoochee River near Norcross, GA at 1,170 square miles, so what passes this gauge is about 4% of the water measured there. Water passing here goes on to Chattahoochee River above Roswell, GA, Chattahoochee River below Morgan Falls Dam, GA and Chatt River at Powers Fy and I-285 near Atlanta, GA.
Normal flows here
Suwanee Creek runs a median of 39 cfs at this gauge across 40 years of record. February is the fullest month at a median 71 cfs, and September the leanest at 23 cfs. The highest daily mean on record is 3,300 cfs in 2009, and the lowest is 1.0 cfs in 1988.

Medians from the USGS daily-statistics record, 1985 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.
