About this gauge

USGS gauge 03383000 sits on the Tradewater River and reads everything draining 255 square miles of the Tradewater basin. Only 246 square miles of that contributes flow in a normal year; the rest is closed basin that does not drain to the river. Its datum sits 361 feet above sea level NAVD88. Daily flow has been on record here since 1941, 85 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 Tradewater River near Providence, KY at 605 square miles, so what passes this gauge is about 42% of the water measured there.
