What this means

The River Rea at Calthorpe Park is running far below normal at 0.08 m.

No reading on record has been lower: the old record low was 0.11 m, from August 1, 1981. That puts it 0.05 m below the median of 0.13 m for mid-October, based on 21 years of readings. A year ago it stood at 0.08 m as well.

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 0.07 m and 0.39 m.

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

Fishing and paddling

At low levels, many rivers become a walk-and-paddle trip. Fish hold in deeper pools and spook easily.

Flood alerts and warnings come from the Environment Agency.
