What this means
The Saint John River at Maugerville is running far below normal at 1.02 m.
The median for mid-October is 1.54 m, based on 21 years of readings, so the water level is 0.53 m below typical. On the same day last year the reading was 1.09 m, a difference of −0.07 m.
It has dropped 0.07 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 0.83 m and 1.30 m.
Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.
