What this means

Swill Brook at Oaksey is running at a record low at −0.29 m.

No reading on record has been lower: the old record low was −0.24 m, from October 10, 2005. That puts it 0.13 m below the median of −0.17 m for mid-October, based on 21 years of readings. A year ago it stood at −0.24 m (−0.05 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 −0.29 m and −0.24 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.
