What this means

Low water at Tahltan River at the Mouth: the gauge reads 3.92 m, far below normal for mid-October.

The median for mid-October is 4.00 m, based on 5 years of readings, so the water level is 0.08 m below typical.

It is still going down, by 0.04 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 3.82 m – 4.11 m.

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