Big Ribble Operational Catchment

About

The Ribble downstream of the Calder is slower moving and meandering. The Hodder confluence just above this point improves the water quality but the pollutants from the heavily urbanised and industrial Calder have a significant impact.

Challenges data for Big Ribble 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.

Objectives data for Big Ribble Operational Catchment

Ecological status or potential objectives for surface water bodies

Table summarises the ecological status and ecological potential objectives set for water bodies in the river basin management plan. Each water body is only counted once in this table. Each water body objective consists of a target status and a date when it was, or is expected to be, met.
