What this means

The Sultan River below Powerplant near Sultan is running below normal at 5.09 ft.

That puts it 0.24 ft below the median of 5.34 ft for mid-October, based on 30 years of readings. A year ago it stood at 5.21 ft (−0.12 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 5.05 ft and 6.18 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that. The sensor also reports a water temperature of 53 °F.
