What this means

Low water at South Thompson River at Chase: the gauge reads 1.32 m, below normal for mid-October.

That puts it 0.35 m below the median of 1.67 m for mid-October, based on 16 years of readings. A year ago it stood at 1.25 m (+0.08 m).

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 1.32 m – 1.42 m.

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