About this gauge
USGS gauge 02398000 sits on the Chattooga River and reads everything draining 192 square miles of the Upper Coosa basin. Its datum sits 613 feet above sea level NAVD88. Daily flow has been on record here since 1937, 89 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 Chattooga River above Gaylesville AL at 366 square miles, so what passes this gauge is about 52% of the water measured there. Water passing here goes on to Coosa River at Leesburg AL.
