What this means

At 1.38 m, the St. Mary River below Morris Creek is below normal for mid-October.

That puts it 0.10 m below the median of 1.48 m for mid-October, based on 16 years of readings. A year ago it stood at 1.31 m (+0.07 m).

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 1.38 m and 1.67 m.

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