Harbertonford Bridge water level

What this means

Low water at Harbertonford Bridge: the gauge reads 0.27 m, far below normal for mid-October.

The median for mid-October is 0.42 m, based on 17 years of readings, so the river level is 0.15 m below typical. On the same day last year the reading was 0.36 m, a difference of −0.09 m. The lowest reading on record is 0.21 m (May 27, 2011).

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 0.26 m – 0.32 m.

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