What this means

South Marston Brook at Highworth Bridge is running at a record low at 0.07 m.

No reading on record has been lower: the old record low was 0.10 m, from August 11, 2022. The usual range here runs from 0.12 m to 1.08 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 0.05 m and 0.30 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.
