About this gauge

USGS gauge 02235200 sits on Blackwater Creek and reads everything draining 126 square miles of the Upper St. Johns basin. Its datum sits 19 feet above sea level NGVD29. Daily flow has been on record here since 1967, 45 years of it.

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 St Johns River near De Land, FL at 3,066 square miles, so what passes this gauge is about 4% of the water measured there.
