What this means

At 5.35 ft, the Fall River above Yellowstone Canal near Squirrel is far below normal for mid-October.

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 5.34 ft and 5.37 ft.

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