What this means

At 0.31 m, the Souris River near Ralph is far below normal for mid-October.

The level is falling, down 0.01 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 0.31 m and 1.25 m.

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