The Derwent is a
riverin the countyof Derbyshire, England. It is 50 miles (80 km) long and is a tributaryof the River Trentwhich it joins south of Derby.

Peak Districtat Bleaklowjust east of Glossopand flows through the Upper Derwent Valleywith its three reservoirs, the Howden Reservoir, Derwent Reservoir and Ladybower Reservoir. It then passes through Bamford, Hathersage, Grindlefordand Baslow, and through the ChatsworthPark estate, and it is joined by the River Wye. After passing through Darley Dale, the Derwent reaches Matlock, before flowing past Cromfordand through the Crich Chase Nature Reserve. The River Derwent supplies Carsington Reservoirindirectly, 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.
