About this gauge

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 Western Run at Western Run, MD at 60 square miles, so what passes this gauge is about 21% of the water measured there.
