River Derwent

The River Derwent winds through the Peak District and its foothills in Derbyshire. It rises at Swains Greave on Bleaklow at 590 metres and travels 50 miles to join the Trent south of Derby. The upper valley holds three reservoirs—Howden, Derwent and Ladybower—fed by tributaries such as the Westend and Ashop. Below these, the river passes villages like Bamford, Hathersage and Baslow before flowing past Chatsworth House. Near Matlock it collects Bentley Brook and continues through Matlock Bath, Cromford and Ambergate, where the Amber joins. The Derwent was central to the Industrial Revolution, powering early cotton mills such as Richard Arkwright’s Cromford Mill. The Derwent Valley Mills World Heritage Site recognises this legacy, with surviving weirs and historic mill complexes at Belper, Darley Abbey and Masson. The river also supplies drinking water through the Derwent Valley Aqueduct to Sheffield, Nottingham, Derby and Leicester. Its waters reach Carsington Reservoir via a pumping station at Ambergate, balancing flows for downstream use. Canoeists enjoy the fast water and slalom course at Matlock Bath, while the valley remains a key route for roads and railways. Visitors find scenic walks along the Upper Derwent Trail and through the Lower Derwent Trail, where wild flowers and otters can be seen. The Heights of Abraham above Matlock Bath offers cable cars and caves, and souvenir shops line Matlock Bath’s promenade. At Chatsworth, the river threads the estate’s parkland, and at Derby the Riverside Gardens sit beside the old mill sites now generating hydro-electricity. The river’s meanders add length to its course, creating gentle bends and broad views across the valley floor.
