Project summary

Edit project overview to modify the project summary.

Colne Water Restoration is a partnership project that will use CRF funds to improve watercourses in an area of the Ribble Catchment that is intensely farmed and urbanised. Some river channels have been heavily modified during the Industrial Revolution. Diffuse pollution, a lack of riparian habitat, unnatural flow regimes attributable to upland drainage and obstructions to fish passage are causing certain watercourses in the Colne Water Catchment to fail to meet the required standards under the Water Framework Directive (WFD). Fish populations, particularly salmonids, have been found to be greatly diminished. To ensure that the failing waterbodies achieve Good Ecological Status under the WFD, the Ribble Rivers Trust aims to improve the habitat and connectivity in order to generate sustainable fish populations. The creation of riparian buffer zones will reduce diffuse pollution from farmland and roads, and some upland drainage grips are to be blocked to encourage a sustainable return to natural flow regimes.

Community Involvement - Practical volunteering activities like river clean-ups, wildlife surveys and tree planting, and awareness raising through walkover surveys and appraisal tours, Public consultation, survey work.
