About this gauge

USGS gauge 02111000 sits on the Yadkin River and reads everything draining 29 square miles of the Upper Yadkin basin. Its datum sits 1,211 feet above sea level NAVD88. Daily flow has been on record here since 1940, 86 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 Yadkin River below W Kerr Scott Dam near Buck, NC at 367 square miles, so what passes this gauge is about 8% of the water measured there. Water passing here goes on to Yadkin River at Wilkesboro, NC.
