About this gauge
USGS gauge 01643395 sits on Soper Branch and reads everything draining 1.2 square miles of the Monocacy basin. Its datum sits 381 feet above sea level NAVD88. Daily flow has been on record here since 2004, 23 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 Bennett Creek at Park Mills, MD at 63 square miles, so what passes this gauge is about 2% of the water measured there. Water passing here goes on to Monocacy River near Dickerson, MD and Potomac River at Edwards Ferry near Poolesville,md.
