What this means

Low water at Trengune: the gauge reads 0.20 m, below normal for mid-October.

The median for mid-October is 0.25 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 0.23 m, a difference of −0.04 m.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 0.19 m – 0.21 m.

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

For anglers and canoeists

Low rivers are hard going for paddlers, with exposed gravel and weirs that are awkward to shoot. Salmon and sea trout usually wait for the next spate to run.

Many angling and canoe clubs check gauges like this one before heading out.
