What this means

Low water at Allerford: the gauge reads −0.09 m, at a record low.

That is below the previous record low of 0.00 m (September 12, 2002), so the gauge is setting a new low. The usual range here runs from 0.00 m to 0.45 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 −0.13 m – −0.02 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.
