Mole Upper Trib Operational Catchment

About

The Upper Mole operational Catchment includes the head waters of the Mole, south of Crawley, which form in to two larger channels, the Mole and the Gatwick Stream. These two channels combine just to the north of Gatwick airport. Two further tributaries join the Mole downstream of Horley, The Burstow Stream and the Salfords stream, which includes the Redhill brook.

Challenges data for Mole Upper Trib 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.
