National Park Rivers At Risk Report Released

A new report, Rivers at Risk, has been published this week by Campaign for National Parks and The Rivers Trust, examining the state of rivers across all 13 National Parks in England and Wales. The findings are clear: while rivers in National Parks are generally in better condition than those outside, they are still under serious threat.

Eryri National Park, right on our doorstep, is included in this analysis. Its rivers are vital for wildlife, local communities, and recreation, yet they too face pressures from pollution, changing land use, and inadequate protection.

Key findings from the report

• Rivers in National Parks are around three times more likely to be classed as in good condition compared to those outside.

• However, many rivers—including those in Eryri—still suffer from agricultural run-off, sewage pollution, and insufficient investment in river management.

• The report highlights six “rivers at risk” across the UK, including the Cleddau in Pembrokeshire, showing that Welsh rivers are particularly vulnerable.

• In 2024, 47,187 hours of sewage were discharged from combined sewage overflows (CSOs) into rivers in Eryri National Park.

What the report calls for

• Stronger legislation and regulation in both England and Wales to protect rivers in National Parks.

• Proper investment in infrastructure, nature-based solutions, and habitat restoration.

• Better use of data and monitoring to hold polluters to account.

• More inclusive engagement, ensuring everyone has the opportunity to help protect these rivers.

At North Wales Rivers Trust, we know the importance of healthy rivers in Eryri. From the Eden and Mawddach to the Glaslyn and Gwyrfai, our catchments are home to internationally important species and habitats. This report reinforces why protecting these waterways matters so much both for nature and for people.
