What this means

Low water at Denham Lodge: the gauge reads 0.06 m, below normal for mid-October.

That puts it 0.02 m below the median of 0.07 m for mid-October, based on 21 years of readings. A year ago it stood at 0.07 m (−0.02 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 0.05 m – 0.07 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 Misbourne

River Misbourne

The River Misbourne is a chalk river that rises in a field on the outskirts of Great Missenden in Buckinghamshire, passing through Little Missenden, Old Amersham, Chalfont St Giles, Chalfont St Peter and under the Chiltern railway line and the M25 motorway to its confluence with the River Colne just north of where the Colne is crossed by Western Avenue, the A40 road. It falls by around 94 m (310 ft) in the course of its 27 km length.
