RIVER DERWENT, NORTH EAST ENGLAND

:''For other rivers called Derwent, see River Derwent.''
The 'River Derwent' is a river on the border between County Durham and Northumberland in the north east of England. It broadens into the Derwent Reservoir west of Consett. The Derwent is a tributary of the River Tyne, which it joins near the MetroCentre.
The name Derwent comes from the Brythonic/Old Welsh word for oak "derw", harking back to the time when the Derwent Valley was inhabited by a British-speaking population.
