About this gauge
USGS gauge 03076100 sits on the Youghiogheny River and reads everything draining 250 square miles of the Youghiogheny basin. Its datum sits 2,017 feet above sea level NAVD88. Daily flow has been on record here since 2011, 15 years of it.
Where this gauge sits in the drainage
Two gauged sites sit upstream of here. The closest is Youghiogheny River near Swallow Falls Park, MD, reading 162 square miles. This gauge adds the 88 square miles that drain in between. Downstream the next reading comes from Youghiogheny River at Friendsville, MD at 295 square miles, so what passes this gauge is about 85% of the water measured there. It then enters Youghiogheny River Lake at Rt 40 Bridge, PA, below which releases set the flow.
