What this means

At 0.04 m, the River Kennet at Marlborough is below normal for mid-October.

That puts it 0.03 m below the median of 0.07 m for mid-October, based on 21 years of readings. A year ago it stood at 0.04 m as well.

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 0.04 m and 0.05 m.

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

On the river at Marlborough

Low, clear water makes fish wary, and anglers often do better early and late in the day. For canoeists, shallow riffles mean scraped hulls and the odd portage.

Flood warnings for the area come from the Environment Agency.

About the River Kennet

River Kennet

The Kennet is a chalk river and a tributary of the River Thames in Southern England. Most of the river is straddled by the North Wessex Downs National Landscape. The lower reaches have been made navigable as the Kennet Navigation, which – together with the Avon Navigation, the Kennet and Avon Canal and the Thames – links the cities of Bristol and London.
