What this means
The Chehalis River near Harrison Mills is running below normal at 8.93 m.
That puts it 0.43 m below the median of 9.36 m for mid-October, based on 16 years of readings. A year ago it stood at 9.72 m (−0.79 m).
It has dropped 0.04 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 8.75 m and 9.98 m.
Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.
