About this gauge

USGS gauge 02232400 sits on the St Johns River and reads everything draining 1,331 square miles of the Upper St. Johns basin. Daily flow has been on record here since 1954, 72 years of it.

Where this gauge sits in the drainage

Lake Poinsett near Cocoa, Fla sits immediately upstream, so dam releases rather than rainfall set the flow here. Two gauged sites sit upstream of here. The closest is Lake Poinsett near Cocoa, Fla, reading 1,272 square miles. This gauge adds the 59 square miles that drain in between. Downstream the next reading comes from St Johns River near Christmas, FL at 1,539 square miles, so what passes this gauge is about 86% of the water measured there. It then enters St Johns River above Lake Harney near Geneva, FL, below which releases set the flow.

Normal flows here

The St Johns River runs a median of 537 cfs at this gauge across 72 years of record. October is the fullest month at a median 1,770 cfs, and May the leanest at 174 cfs. The highest daily mean on record is 10,700 cfs in 1954, and the lowest is -535.0 cfs in 2025.

Medians from the USGS daily-statistics record, 1954 to 2026. A month at 100% is running at its own long-term median.
