What this means

Low water at Westy: the gauge reads 3.75 m, below normal for mid-October.

That puts it 0.15 m below the median of 3.90 m for mid-October, based on 21 years of readings. A year ago it stood at 3.62 m (+0.13 m).

It is still going down, by 0.20 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 2.98 m – 4.30 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.

About the River Mersey

River Mersey

The River Mersey is a major river in North West England. Its name derives from Old English and means "boundary river", possibly referring to its having been a border between the ancient kingdoms of Mercia and Northumbria. For centuries it has formed part of the boundary between the historic counties of Lancashire and Cheshire.
