The River Derwent is one of England's most storied fishing rivers, with multiple distinct waterways sharing the name flowing through Derbyshire, Cumbria, Yorkshire, and the Northeast. The Derbyshire Derwent runs approximately 66 miles through rural countryside, serving as a vital water source for nearby cities while offering excellent trout and grayling fishing. The Cumbrian Derwent rises beneath Scafell Pike, flows through Derwentwater and Bassenthwaite Lake, passes through the Lake District National Park and the town of Cockermouth, and ultimately enters the Irish Sea at Workington — making it one of the finest salmon and sea trout rivers in northern England. The Northeast Derwent, a tributary of the River Tyne, has undergone a remarkable conservation transformation over the past decade, with salmon and sea trout now flourishing along more than 20 miles of the main river. The Yorkshire Derwent flows 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 meeting the River Ouse. Across all its iterations, the River Derwent offers a diverse and rewarding angling experience for fly fishers, coarse anglers, and game fishers alike.
