The Derwent is a river in the county of Derbyshire, England. It is 50 miles (80 km) long and is a tributary of the River Trent which it joins south of Derby.

Route

It rises in the Peak District at Bleaklow just east of Glossop and flows through the Upper Derwent Valley with its three reservoirs, the Howden Reservoir, Derwent Reservoir and Ladybower Reservoir. It then passes through Bamford, Hathersage, Grindleford and Baslow, and through the Chatsworth Park estate, and it is joined by the River Wye. After passing through Darley Dale, the Derwent reaches Matlock, before flowing past Cromford and through the Crich Chase Nature Reserve. The River Derwent supplies Carsington Reservoir indirectly, with the water pumped from the river at Ambergate Pumping Station in times of high flow, and then released when flows are low via the same 6.5 mile (10.5km) of tunnels and aqueducts built by Severn Trent Water. This allows greater abstraction rates upstream in the drier summer months.

Industry

The river was used to power many cotton mills in the Derwent Valley Mills area around Matlock and Cromford.

It is the habitat for many different animals such as otters and fish.

It also provides the name for the oldest field hockey club in Derbyshire. Derwent Hockey Club, established in 1897, played its matches on the banks of the Derwent in Darley Dale, before locating to Wirksworth.
