What this means

At 35.10 m, the River Arun at Provender Mill is far below normal for mid-October.

That puts it 0.18 m below the median of 35.28 m for mid-October, based on 20 years of readings. A year ago it stood at 35.17 m (−0.07 m). The lowest reading on record is 34.30 m (January 5, 2016).

The level is falling, down 0.06 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 34.68 m and 35.21 m.

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

On the river at Provender Mill

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 Arun

River Arun

The River Arun is a river in the English county of West Sussex. At 37 miles (60 km) long, it is the longest river entirely in Sussex and one of the longest starting in Sussex after the River Medway, River Wey and River Mole. From the series of small streams that form its source in the area of St Leonard's Forest in the Weald, the Arun flows westwards through Horsham to Nowhurst where it is joined by the North River. Turning to the south, it is joined by its main tributary, the western River Rother, and continues through a gap in the South Downs to Arundel to join the English Channel at Littlehampton. It is one of the faster flowing rivers in England, and is tidal as far inland as Pallingham Quay, 25.5 miles (41.0 km) upstream from the sea at Littlehampton. The Arun gives its name to the Arun local government district of West Sussex.
