River Darwen

The River Darwen is a river running through Darwen and Blackburn in Lancashire.

The river was seriously polluted with human and industrial effluent during the Industrial Revolution, up to the early 1970s. The river often changed colour dramatically as a result of paper and paint mills routinely using river water to flush out dye and paint tanks. This has now ceased and the river is relatively clear with the return of trout and small fish.

Rising in Jack's Key Clough at the confluence of Grain Brook and Grainings Brook, two streams from Bull Hill and Cranberry Moss respectively, the river flows through the town of Darwen, continuing into the suburbs of Blackburn past Ewood Park. The river passes below the Leeds and Liverpool Canal at Ewood Aqueduct and is culverted again at Waterfall and near Griffin Park. It is joined by the River Blakewater near Witton Country Park in Blackburn and leaves the mostly urban landscapes of the towns behind, flowing through parklands and valleys. A further tributary, the River Roddlesworth, joins the Darwen at the bottom of Moulden Brow on the boundary between Blackburn with Darwen and Chorley Borough Council (the name Moulden Brow being associated with Moulden Water, an alternative name for this stretch of the river). From there, the Darwen flows past Hoghton Tower through Hoghton Bottoms and Samlesbury Bottoms, finally combining with the River Ribble at Walton-le-Dale.

A small Memorial Garden for Kathleen Ferrier is on the river bank at Higher Walton, Lancashire.

At Walton-le-Dale, the river was the backdrop the Battle of Preston during the Second English Civil War, a Parliamentarian victory immortalised in John Milton's poem "To Cromwell": -

While Darwent Streams with Blood of Scots imbru'd...

In this poem, the river appears to be named "Darwent," giving evidence of its derivation from a Brythonic dialect form similar to the Old Welsh derwenyd (Modern Welsh derwenydd), meaning "valley thick with oaks".
