About

The catchment of the River Derwent covers an area of 1,197km2, covering much of the county of Derbyshire. The Derbyshire Derwent is a major tributary of the River Trent. Rising on Howden Moor, the Derwent is impounded by three public water supply reservoirs. It flows through a rural landscape towards the urban areas of Matlock and Derby.

Challenges data for Derwent Derbyshire Management Catchment

Reasons for not achieving good status by business sector

The issues preventing waters reaching good status and the sectors identified as contributing to them. The numbers in the table are individual counts of the reasons for not achieving good status with a confidence status of 'confirmed' and 'probable', where the latest classification is less than good status. There may be more than one reason in a single water body. Note, table does not include reasons for deterioration.
