What this means

At 10.07 ft, the East Fork Lewis River near Heisson is far below normal for mid-October.

The median for mid-October is 10.81 ft, based on 27 years of readings, so the river stage is 0.74 ft below typical. It is 9.93 ft below the flood stage of 20.00 ft. On the same day last year the reading was 11.32 ft, a difference of −1.25 ft.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 10.03 ft and 10.41 ft.

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

What the stage means on the water

Low water means more dragging on shallow riffles and slower floats. Fish crowd into the deeper runs, and warm, low water stresses them, so play and release them quickly.

The National Weather Service puts flood stage for this gauge at 20.00 ft, still 9.93 ft away.
