Drainage area: ~36.8 sq.mi.

At the uppermost listed put-in, drainage area (as calculated by USGS StreamStats 4.0 beta software) is 36.8 square miles. This is roughly 1/4 the drainage at the gauge (Popple River, near Fence), thus flows here could be roughly 1/4th the gauge reading. Expect the gauge to lag flows up here on both rise and fall.
