About this gauge

USGS gauge 02234324 sits on Howell Creek and reads everything draining 29 square miles of the Upper St. Johns basin. Daily flow has been on record here since 1972, 53 years of it.

Where this gauge sits in the drainage

Lake Howell near Casselberry, Fla sits immediately upstream, so dam releases rather than rainfall set the flow here. Four gauged sites sit upstream of here. The closest is Lake Howell near Casselberry, Fla, reading 28 square miles. This gauge adds the 1.4 square miles that drain in between. Downstream the next reading comes from Howell Creek at State Hwy 434 near Oviedo, FL at 52 square miles, so what passes this gauge is about 56% of the water measured there. Water passing here goes on to St Johns River near Sanford, FL and St Johns River near De Land, FL. It then enters Lake Jesup Outlet near Sanford, FL, below which releases set the flow.
