Ouzel and Milton Keynes Operational Catchment

About

The River Ouzel rises from chalk springs in the Chilterns. It flows northwards, through Leighton Buzzard, skirts east of Milton Keynes and joins the River Great Ouse at Newport Pagnell. The Clipstone and Broughton Brooks are its main tributaries. This catchment also includes a short section of River Great Ouse (Wolverton to Newport Pagnell), the Loughton Brook (draining west Milton Keynes) and Tathall Brook to the north. The Grand Union Canal runs north-south along the River Ouzel valley. Milton Keynes, a major urban area, dominates the north of the catchment. The rest of the catchment is mainly rural.

Challenges data for Ouzel and Milton Keynes Operational 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.
