What this means
Avon Mill is running far below normal at 47.71 m.
The median for mid-October is 49.04 m, based on 16 years of readings, so the river level is 1.33 m below typical. On the same day last year the reading was 47.70 m, a difference of +0.01 m.
It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 47.67 m and 47.82 m.
Autumn rain usually starts to lift rivers again after the summer low.
