What this means
Low water at Saint John River at Saint John: the gauge reads 0.85 m, far below normal for mid-October.
The median for mid-October is 1.30 m, based on 21 years of readings, so the water level is 0.46 m below typical. On the same day last year the reading was 1.00 m, a difference of −0.16 m.
It is still going down, by 0.19 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 0.59 m – 1.34 m.
Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.
