The River Derwent is one of England's most celebrated fishing rivers, with multiple distinct waterways sharing the name flowing through Cumbria, Derbyshire, and Yorkshire. The Cumbrian Derwent rises beneath Scafell Pike, flows through Derwentwater and Bassenthwaite Lake, passes through the rolling countryside of the Derwent Valley and the town of Cockermouth, and ultimately enters the Irish Sea at Workington — a journey through some of the most dramatic scenery in the Lake District National Park. The Derbyshire Derwent flows for 66 miles through rural Derbyshire, passing through Chatsworth Park and the village of Matlock Bath before continuing south. The Yorkshire Derwent runs for approximately 100 miles from its source at Lilla Rig on Fylingdales Moor, through the North Yorkshire Moors National Park, the Vale of Pickering, and the Vale of York before joining the River Ouse. Together, these rivers offer an extraordinary diversity of fishing experiences, from wild salmon and sea trout runs in Cumbria to classic chalk-stream-style trout and grayling fishing in Derbyshire and coarse fishing in Yorkshire.
