About this gauge
USGS gauge 03176500 sits on the New River and reads everything draining 3,770 square miles of the Middle New basin. Its datum sits 1,490 feet above sea level NAVD88. Daily flow has been on record here since 1939, 88 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 Bluestone Lake near Hinton, WV at 4,608 square miles, so what passes this gauge is about 82% of the water measured there.
