About this gauge

USGS gauge 03322420 sits on the Ohio River and reads everything draining 108,000 square miles of the Highland-Pigeon basin. Its datum sits 311 feet above sea level NAVD88. Daily flow is on record here from 1985 to 1993, 9 years in all.

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 Ohio River at Old Shawneetown, Il-Ky at 141,000 square miles, so what passes this gauge is about 77% of the water measured there.

Normal flows here

The Ohio River runs a median of 106,000 cfs at this gauge across 9 years of record. March is the fullest month at a median 224,000 cfs, and August the leanest at 30,100 cfs. The highest daily mean on record is 720,000 cfs in 1991, and the lowest is 4,780 cfs in 1988.

Medians from the USGS daily-statistics record, 1985 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 Ohio River reaches flood stage at this gauge at 37 feet. NWS starts watching it at 33 feet. The highest crest on record is 64.4 feet, in February 1937.
