What this means

At 0.33 m, the River Colne at Farlows Bridge is far below normal for mid-October.

The median for mid-October is 0.43 m, based on 9 years of readings, so the river level is 0.10 m below typical. On the same day last year the reading was 0.34 m, a difference of −0.01 m. The lowest reading on record is 0.14 m (February 27, 2019).

The level is falling, down 0.02 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 0.30 m and 0.40 m.

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

On the river at Farlows Bridge

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.
