What this means

Henrys Fork near Ashton is running far below normal at 2.72 ft.

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 2.71 ft and 2.77 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.
