What this means

Low water at St Johns: the gauge reads 2.52 m, far below normal for mid-October.

That puts it 0.09 m below the median of 2.62 m for mid-October, based on 18 years of readings. A year ago it stood at 2.53 m (−0.01 m).

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 2.51 m – 2.54 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.
