About this gauge
USGS gauge 02070000 sits on the North Mayo River and reads everything draining 108 square miles of the Upper Dan basin. Its datum sits 730 feet above sea level NAVD88. Daily flow has been on record here since 1929, 96 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 Mayo River near Price, NC at 242 square miles, so what passes this gauge is about 45% of the water measured there. Water passing here goes on to Dan River near Wentworth, NC.
