West Ayton water level

What this means

At −0.20 m, the River Derwent at West Ayton is at a record low.

It has now dropped past the published record low of −0.07 m (October 1, 1997). That puts it 0.34 m below the median of 0.14 m for mid-October, based on 21 years of readings. A year ago it stood at −0.22 m (+0.02 m).

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between −0.22 m and 0.09 m.

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