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 Leaf River at Hattiesburg, MS at 1,748 square miles, so what passes this gauge is about 43% of the water measured there.
