About this gauge

USGS gauge 02338000 sits on the Chattahoochee River and reads everything draining 2,430 square miles of the Middle Chattahoochee-Lake Harding basin. Its datum sits 682 feet above sea level NAVD88. Daily flow has been on record here since 1965, 61 years of it.

Where this gauge sits in the drainage

Six gauged sites sit upstream of here. The closest is Chattahoochee River above Bear Creek, near Rico, GA, reading 2,130 square miles. This gauge adds the 300 square miles that drain in between. Downstream the next reading comes from Chattahoochee River at GA 100, at Franklin, GA at 2,680 square miles, so what passes this gauge is about 91% of the water measured there. It then enters Chattahoochee River near Lagrange, GA, below which releases set the flow.
