What this means

Bonaparte Creek at Tonasket is running far below normal at 1.06 ft.

The median for mid-October is 1.35 ft, based on 10 years of readings, so the river stage is 0.28 ft below typical. On the same day last year the reading was 1.32 ft, a difference of −0.26 ft.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 0.93 ft and 1.07 ft.

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