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 Wilson Lake near Florence, Al at 30,750 square miles, so what passes this gauge is about 1% of the water measured there.
