About this gauge

USGS gauge 02342850 sits on Hannahatchee Creek and reads everything draining 121 square miles of the Middle Chattahoochee-Walter F basin. Its datum sits 233 feet above sea level NAVD88. Daily flow has been on record here since 1964, 19 years of it.

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 at Spur 39, near Omaha, GA at 5,910 square miles, so what passes this gauge is about 2% of the water measured there.

Normal flows here

Hannahatchee Creek runs a median of 47 cfs at this gauge across 19 years of record. March is the fullest month at a median 97 cfs, and September the leanest at 26 cfs. The highest daily mean on record is 5,030 cfs in 2009, and the lowest is 5.0 cfs in 2012.

Medians from the USGS daily-statistics record, 1964 to 2026. A month at 100% is running at its own long-term median.

Flood stages and record crests

Hannahatchee Creek reaches flood stage at this gauge at 16 feet. NWS starts watching it at 14 feet. The highest crest on record is 15.5 feet, in December 2015.
