Where this gauge sits in the drainage

Two gauged sites sit upstream of here. The closest is Oostanaula River at Calhoun, GA, reading 1,624 square miles. This gauge adds the 491 square miles that drain in between. Downstream the next reading comes from Oostanaula River at US 27, at Rome, GA at 2,149 square miles, so what passes this gauge is about 98% of the water measured there. Water passing here goes on to Coosa River at State Line, Al/ga.

Normal flows here

The Oostanaula River runs a median of 1,930 cfs at this gauge across 46 years of record. March is the fullest month at a median 4,720 cfs, and September the leanest at 930 cfs. The highest daily mean on record is 42,300 cfs in 1990, and the lowest is 312 cfs in 2011.

Medians from the USGS daily-statistics record, 1975 to 2020. 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.
