What this means

The River Marden at Stanley is running far below normal at 0.36 m.

That puts it 0.11 m below the median of 0.47 m for mid-October, based on 21 years of readings. A year ago it stood at 0.36 m (−0.01 m). The lowest reading on record is 0.14 m (September 30, 1982).

It has dropped 0.04 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 0.35 m and 0.39 m.

Autumn rain usually starts to lift rivers again after the summer low.

Fishing and paddling

At low levels, many rivers become a walk-and-paddle trip. Fish hold in deeper pools and spook easily.

Flood alerts and warnings come from the Environment Agency.
