About this gauge

USGS gauge 02330450 sits on the Chattahoochee River and reads everything draining 45 square miles of the Upper Chattahoochee basin. Its datum sits 1,404 feet above sea level NGVD29. Daily flow has been on record here since 1981, 45 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 near Leaf, GA at 150 square miles, so what passes this gauge is about 30% of the water measured there. Water passing here goes on to Chattahoochee River near Cornelia, GA.
