About this gauge
USGS gauge 02336340 sits on Nancy Creek and reads everything draining 18 square miles of the Upper Chattahoochee basin. Its datum sits 837 feet above sea level NAVD88. Daily flow has been on record here since 2012, 14 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 Nancy Creek at Rickenbacker Drive, at Atlanta, GA at 27 square miles, so what passes this gauge is about 67% of the water measured there. Water passing here goes on to Nancy Creek at West Wesley Road, at Atlanta, GA, Chattahoochee River at GA 280, near Atlanta, GA and Chattahoochee River near Fairburn, GA. It then enters Nancy Creek at Lake Forest Road, at Atlanta, GA, below which releases set the flow.
