The Course of the Yarrow
 | Our Lancashire River Yarrow rises on Anglezarke Moor, (left), close to Rivington Moor (photo to right), and soon becomes a tree lined gorge. | 
|
| The Yarrow drains into a series of reservoirs, first the Yarrow Reservoir, and then into the adjoining Anglezarke and Rivington reservoirs. The construction of these reservoirs arose from an Act of Parliament in 1847, allowing the growing city of Liverpool to impound the waters of the River Douglas, Yarrow and the Hoddlesworth. Work began in 1852 and the supply to Liverpool commenced in 1857.

| The name Yarrow is a generic name for river - hence a number of River Yarrows in other parts of Britain - one of the best known the Yarrow tributary of the Tweed. | ||
| The Yarrow emerges from Rivington Reservoir, to begin its 18 mile course to join the Douglas at the Redbridge, near Sollom - a tidal reach at this point - the eventual discharge is via the Ribble Estuary into the Irish Sea. There are five main tributaries of the Yarrow; Black Brook, River Chor, near Chorley, Cullbeck Brook, Syd Brook and Lostock, near Croston. | ||
