What this means

The River Avon at Salisbury Harnham Bridge is running below normal at 0.27 m.

That puts it 0.16 m below the median of 0.44 m for mid-October, based on 20 years of readings. A year ago it stood at 0.21 m (+0.06 m).

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 0.26 m and 0.36 m.

Autumn rain usually starts to lift rivers again after the summer low.
