About this gauge

USGS gauge 03315500 sits on the Green River and reads everything draining 5,404 square miles of the Middle Green basin. Only 4,045 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 379 feet above sea level NAVD88. Daily flow is on record here from 1970 to 1993, 24 years in all.

Where this gauge sits in the drainage

Two gauged sites sit upstream of here. The closest is Green River at Hwy 259 at Brownsville, KY, reading 2,762 square miles. This gauge adds the 2,642 square miles that drain in between. Downstream the next reading comes from Green River at Rochester, KY at 5,770 square miles, so what passes this gauge is about 94% of the water measured there. Water passing here goes on to Green River at Paradise, KY.

Normal flows here

The Green River runs a median of 5,630 cfs at this gauge across 24 years of record. February is the fullest month at a median 16,500 cfs, and August the leanest at 1,470 cfs. The highest daily mean on record is 101,000 cfs in 1979, and the lowest is 359 cfs in 1991.

Medians from the USGS daily-statistics record, 1970 to 1993. A month at 100% is running at its own long-term median. USGS stopped publishing a daily flow record at this gauge, so these are historical norms, not a baseline for current readings.

Flood stages and record crests

The Green River reaches flood stage at this gauge at 26 feet. NWS starts watching it at 24 feet. The highest crest on record is 52.7 feet, in January 1937.
