What this means
Avon Weir is running below normal at 50.49 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 50.46 m and 50.55 m.
Autumn rain usually starts to lift rivers again after the summer low.
