About this gauge

USGS gauge 01638350 sits on the South Fork Catoctin Creek and reads everything draining 32 square miles of the Middle Potomac-Catoctin basin. Its datum sits 336 feet above sea level NAVD88. Daily flow has been on record here since 2001, 25 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 Catoctin Creek at Taylorstown, VA at 90 square miles, so what passes this gauge is about 35% of the water measured there. Water passing here goes on to Potomac River at Point of Rocks, MD and Potomac River at Edwards Ferry near Poolesville,md.
