The heat waves have caused concern with river temperatures reaching 18 degrees, almost close to the point where there is not enough oxygen in the water for our fish and other wildlife. The Dyfi Rivers Trust is taking action to make the catchment more resilience to climate change, gaining funds to ensure more shading, reduced agricultural and soil erosion run-off and limiting stock access for cleaner waters.
With our partners we are also monitoring Dŵr Cymru Welsh Water to try to ensure they are taking planned actions to upgrade our sewage plants and limiting raw sewage releases. However figures, released by Natural Resources Wales (NRW) in July 2025, show the water company was responsible for 155 pollution incidents across Wales in 2024 – an increase of 42% in the past 10 years.
Welsh Water, the BBC reports, accepts its performance “is not where it needs to be” and says it is accelerating investment in key areas to reduce pollution incidents.
