latest Water Quality Assessments
Natural Resources Wales (NRW) has recently published the latest water quality assessments for Welsh rivers, covering the period from 2020 to 2023. These assessments include both the nine Welsh Special Area of Conservation (SAC) rivers and the broader Water Framework Directive (WFD) results for all rivers across Wales.
Water Quality Status in North Wales
While the overall results show no improvement in the number of rivers meeting their water quality targets, there are specific findings that concern the North Wales catchments, particularly those of the Afon Eden and Afon Gwyrfai, which are both failing their phosphate targets. This brings the number of SAC rivers passing phosphate targets down to just two, compared to four in 2021.
Afon Eden: Although one sample showed a failure in the Eden, it will not subject to nutrient neutrality restrictions. However, its overall phosphate levels are a concern.
Afon Gwyrfai: This river has now officially failed its phosphate target, and any planning decisions in this catchment will now be subject to nutrient neutrality restrictions, alongside other rivers like the Wye, Usk, and Dee.
These phosphate failures are worrying as they reflect the ongoing challenges in maintaining water quality, especially in rivers impacted by agricultural practices, where voluntary measures have not been enough to drive significant improvements.
Fish Populations and Water Quality Concerns
Another concerning development highlighted in the report is the decline in fish stocks, which is the largest contributor to new waterbody failures. Low fish numbers in Welsh rivers, including those in North Wales, are an indicator of the wider water quality problems that persist, especially in SAC-designated rivers.
Cypermethrin and its Impact on Aquatic Life
The report also raised alarms about the ongoing use of cypermethrin, a toxic insecticide that continues to impact river ecosystems. Although banned as a sheep dip in Wales due to its harmful effects on aquatic life, cypermethrin is still used in domestic pesticides and unregulated forestry practices. This highlights the need for stricter controls on its use, as its presence is contributing to the deterioration of river health across Wales.
Looking Ahead
With only two years remaining until the 2027 Water Framework Directive targets are meant to be achieved, the chances of meeting these goals are slim without significant changes in management practices. It is clear that more stringent measures are needed, especially in sectors such as agriculture, which are heavily influencing water quality outcomes.
As we continue our efforts to improve the health of rivers in North Wales, the findings of this report underscore the need for more action to protect our vital water systems. The North Wales Rivers Trust remains committed to working with local communities and partners to address these challenges and restore the health of our rivers.
