About this gauge

USGS gauge 02391540 sits on Sharp Mountain Creek and reads everything draining 73 square miles of the Etowah basin. Its datum sits 891 feet above sea level NAVD88. Daily flow has been on record here since 2005, 21 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 Etowah River Downstream of I-575, at Canton, GA at 600 square miles, so what passes this gauge is about 12% of the water measured there. Water passing here goes on to Etowah River at Canton, GA and Etowah River Allatoona Dam Tw, above Cartersville,ga.
