Waddon Ponds water level

What this means

The River Wandle at Waddon Ponds is running far below normal at −0.11 m.

That puts it 0.16 m below the median of 0.05 m for mid-October, based on 14 years of readings. A year ago it stood at 0.03 m (−0.14 m). The lowest reading on record is −0.25 m (October 12, 2005).

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 −0.11 m and 0.02 m.

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