About this gauge

USGS gauge 02400100 sits on Terrapin Creek and reads everything draining 252 square miles of the Upper Coosa basin. Its datum sits 539 feet above sea level NAVD88. Daily flow has been on record here since 1963, 51 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 Coosa River at Adams Ferry Br near Ballplay, AL at 5,605 square miles, so what passes this gauge is about 4% of the water measured there.
