About this gauge

USGS gauge 02335910 sits on Rottenwood Creek and reads everything draining 19 square miles of the Upper Chattahoochee basin. Its datum sits 820 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 at US 41, at Atlanta, GA at 1,440 square miles, so what passes this gauge is about 1% of the water measured there. Water passing here goes on to Chattahoochee River at Atlanta, GA, Chattahoochee River at GA 280, near Atlanta, GA and Chattahoochee River near Fairburn, GA.
