For anglers and canoeists

A river in spate is no place for beginners. Weirs form strong towbacks, and trees in the water become strainers.

Many angling and canoe clubs check gauges like this one before heading out.

About the River Yarrow

River Yarrow (Lancashire)

The River Yarrow is in Lancashire, with its source at an area called Will Narr at Hordern Stoops, along Spitlers Edge - the Chorley/Blackburn boundary - on the West Pennine Moors. The river feeds the Yarrow Reservoir, which in turn feeds the Anglezarke and Upper and Lower Rivington Reservoirs. Upon leaving the reservoirs via a pumping station, the river passes through an area that was formerly known as Abyssinia. Currently, this area is within the boundaries of Heath Charnock and Limbrick, but the original name was given because it was a route frequented by coal miners, and the workers were said to look like natives of Abyssinia : until the mid 20th century it was usual for miners to return from work covered in coal dust.
