What this means

Low water at Swanage King Georges Field St Marys Church: the gauge reads −0.03 m, at a record low.

That is below the previous record low of 0.00 m (September 3, 2004), so the gauge is setting a new low. The median for late October is 0.02 m, based on 20 years of readings, so the river level is 0.05 m below typical. On the same day last year the reading was −0.02 m, a difference of −0.01 m.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly.

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.
