What this means

At 0.35 m, the River Stour at Lamarsh is far below normal for mid-October.

The median for mid-October is 0.42 m, based on 21 years of readings, so the river level is 0.06 m below typical. On the same day last year the reading was 0.49 m, a difference of −0.14 m. The lowest reading on record is 0.25 m (August 21, 1998).

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 0.35 m and 0.36 m.

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

On the river at Lamarsh

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 Stour

River Stour, Kent

The River Stour is a river in Kent, England that flows into the North Sea at Pegwell Bay. Above Plucks Gutter, where the Little Stour joins it, the river is normally known as the Great Stour. The upper section of the river, above its confluence with the East Stour at Ashford is sometimes known as the Upper Great Stour or West Stour. In the tidal lower reaches, the artificial Stonar Cut short cuts a large loop in the natural river.
