About this gauge

USGS gauge 02335790 sits on Willeo Creek and reads everything draining 16 square miles of the Upper Chattahoochee basin. Its datum sits 856 feet above sea level NAVD88. Daily flow has been on record here since 2007, 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 below Morgan Falls Dam, GA at 1,370 square miles, so what passes this gauge is about 1% of the water measured there. Water passing here goes on to Chatt River at Powers Fy and I-285 near Atlanta, GA, Chattahoochee River at US 41, at Atlanta, GA and Chattahoochee River at Atlanta, GA.

Normal flows here

Willeo Creek runs a median of 11 cfs at this gauge across 19 years of record. February is the fullest month at a median 19 cfs, and September the leanest at 4.5 cfs. The highest daily mean on record is 2,200 cfs in 2009, and the lowest is 0.1 cfs in 2017.
