About this gauge

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 Obion River at Hwy 51 near Obion, TN at 1,875 square miles, so what passes this gauge is about 20% of the water measured there.
