What this means

Low water at Serpent River at Highway No. 17: the gauge reads 7.67 m, below normal for mid-October.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 7.48 m – 7.69 m.

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