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 Catawba River at NC Highway 16 near Millersville, NC at 1,310 square miles, so what passes this gauge is about 3% of the water measured there. Water passing here goes on to Catawba River below Lookout Shoals Dam near Sharon, NC. It then enters Lake Hickory on Catawba River near Taylorsville, NC, below which releases set the flow.
