About this gauge

USGS gauge 03311513 sits on the Green River and reads everything draining 2,762 square miles of the Upper Green basin. Only 600 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 383 feet above sea level NAVD88.

Where this gauge sits in the drainage

Two gauged sites sit upstream of here. The closest is Green River at Mammoth Cave, KY, reading 2,020 square miles. This gauge adds the 742 square miles that drain in between. Downstream the next reading comes from Green River at Lock 4 at Woodbury, KY at 5,404 square miles, so what passes this gauge is about 51% of the water measured there.
