About this gauge

USGS gauge 01673800 sits on the Po River and reads everything draining 78 square miles of the Mattaponi basin. Its datum sits 182 feet above sea level NAVD88. Daily flow has been on record here since 1963, 63 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 Mattaponi River near Bowling Green, VA at 256 square miles, so what passes this gauge is about 30% of the water measured there.
