What this means

At 78.08 m, the Bourne Rivulet at St Mary Bourne is below normal for mid-October.

The median for mid-October is 78.12 m, based on 15 years of readings, so the river level is 0.04 m below typical. On the same day last year the reading was 78.13 m, a difference of −0.05 m.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 78.08 m and 78.12 m.

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

On the river at St Mary Bourne

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.
