What this means

The Jean-Marie River at Highway No. 1 is running far below normal at 1.64 m.

The median for mid-October is 1.85 m, based on 19 years of readings, so the water level is 0.21 m below typical.

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 1.63 m and 1.65 m.

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