About this gauge

USGS gauge 03415000 sits on the West Fork Obey River and reads everything draining 115 square miles of the Obey basin. Only 81 square miles of that contributes flow in a normal year; the rest is closed basin that does not drain to the river. Its datum sits 681 feet above sea level NAVD88. Daily flow has been on record here since 1943, 53 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 Dale Hollow Lake near Celina at 936 square miles, so what passes this gauge is about 12% of the water measured there.
