River Derwent: Facts and Information

Here are some facts about the River Derwent.

  • The River Derwent is 106 km long, and flows entirely in the county of Derbyshire. Half of its course is within the beautiful Peak District National Park.
  • England has three other Derwent Rivers, and there is one in Tasmania, Australia. The name probably comes from an ancient Celtic word meaning ‘belonging to a forest of oak trees’.
  • Its source is at Swains Greave, near the market town of Glossop and near the 633 metre high summit of Bleaklow Head. The Derwent joins the River Trent near Derby.
  • The River Derwent played an important part in the Industrial Revolution. It provided the power for cotton and textile mills, including the first one powered by water, Cromford Mill.
