About this gauge

USGS gauge 03433500 sits on the Harpeth River and reads everything draining 409 square miles of the Harpeth basin. Only 393 square miles of that contributes flow in a normal year; the rest is closed basin that does not drain to the river. Its datum sits 541 feet above sea level NAVD88. Daily flow has been on record here since 1932, 95 years of it.

Where this gauge sits in the drainage

Five gauged sites sit upstream of here. The closest is Harpeth River at Mile 81.33 near Berrys Chapel, TN, reading 213 square miles. This gauge adds the 196 square miles that drain in between. Downstream the next reading comes from Harpeth River near Kingston Springs, TN at 683 square miles, so what passes this gauge is about 60% of the water measured there.
