National Park: Rivers at Risk Report Launched
Our new research shows National Park rivers are being failed by government and water regulators and are now under threat.
Published: 16 September 2025
Today, in partnership with The Rivers Trust, we’ve launched our Rivers at Risk Report, setting out the latest full assessment of the state of rivers across the National Parks of England and Wales. It provides evidence of the current situation and identifies the changes needed to policy, legislation and practice to secure the step-change in progress that is so urgently needed.
The waterways of the UK’s National Parks are iconic: internationally renowned wetlands, glacial lakes, chalk streams and some of the most biodiverse and sensitive rivers, they support natural flood management, help tackle climate change, and are much valued by millions of people as places for recreation and relaxation. These waterways are the lifeblood of our most precious landscapes.
National Parks were designated to preserve and enhance natural beauty, habitats and wildlife: we might expect their waters to be free from pollution, in far greater condition than other waterways, and protected to the highest standards. Yet this is not the case. Water in National Parks faces many challenges, just as it does across the UK.
Dr Rose O’Neill, Chief Executive, Campaign for National ParksAs home to some of the UK’s most precious and globally renowned waterways, National Parks should set the gold standard for clean and healthy rivers. You’d expect National Park freshwaters to be protected like the national treasures they are, but instead they are being ignored and neglected by Government, regulators and water companies. These are rivers loved by millions of people: if we can’t protect the jewels of our waterways, then we are failing the nation.
Working with the Rivers Trust who provided in depth data analysis of the state of rivers, our research included analysis of publicly available data looking at trends for each of the 13 National Parks as well as six rivers at risk: River Cleddau (Pembrokeshire Coast), the Wye (Peak District), Meon (South Downs), Lymington (New Forest), Bure (Broads) and Pulham (Exmoor).
We used freedom of information requests to secure new information on how National Park rivers fared in the water company price review process, and related decisions made by water companies and the regulators. Finally, we looked at the latest National Park Management Plans to review their water ambitions.
Working together on this report with the Rivers Trust, we have identified the work we can do jointly to support improved water management in National Parks. It is clear that there is still a significant amount of work to be done to better understand the state, pressures and drivers for change within National Park waterways. We are currently exploring how we might fund development of a mapping tool to support National Park Authorities and others better access the huge amount of water data that is available. We are also developing ways to celebrate and support people’s connection with National Park waterways, as part of ensuring that every citizen, no matter their age, race, class or where they live, feels welcome and connected to National Parks.
We’re demanding urgent action from Government in England and Wales to protect and prioritise National Park waterways. Campaign for National Parks have launched a public action calling on Ministers in England and Wales to finally give National Park waters the protection they deserve and implement the full recommendations from the Rivers at Risk report.
David Johnson, Technical Director, The Rivers TrustAll data tells a story, and unfortunately this data presents a tragic tale of underinvestment and mismanagement of the rivers that flow across our most iconic landscapes. This report makes clear that serious action is needed to secure and enhance protection for rivers in our National Parks, and to be even more ambitious in future so the cycle of pollution and destruction can be broken.
“Water is inextricably linked with many of our cherished National Parks and remains a lifeblood of countless Protected Landscapes. This research highlights that rivers in National Parks are three times more likely to be assessed as in good condition compared to outside our landscapes. This is in no small part down to the work of National Park Authorities, with communities, farmers, landowners and government agencies to improve habitats, restore peat, reduce pollution and tackle invasive species. We know there’s no single action and only concerted effort across our water systems and catchments will lift water quality to the high levels the public rightly expects.
We need to go further and faster in National Parks to meet the target of 30% of land being conserved for nature. Waterways are the cornerstone of our habitats. Yet, as the report illustrates, our efforts are hampered by poor infrastructure, lack of investment and weak regulation. We need government to, as promised, come forward with new legislation to prioritise action in our National Parks and Protected Landscapes, building on the duty on relevant authorities, including water companies, to seek to further National Parks’ statutory purposes.” – Vanessa Rowlands, Chair, National Parks England
“We are dismayed, but not surprised, that rivers in our treasured National Parks are polluted. These waters should be the cleanest in the country, yet they are treated as open sewers by profit-driven water companies and poorly regulated industrial-scale agriculture. The system is broken. Ofwat has failed and must be replaced with a regulator that puts people and nature before dividends. The Environment Agency must be properly resourced to enforce the law. We also need to end the failed experiment of water company privatisation and transition to a model where they are run for public benefit. Alongside this, there must be investment in nature-friendly farming and ambitious river restoration. Our National Parks deserve nothing less – and the public will not tolerate more excuses.” – James Wallace, Chief Executive, River Action
“National Parks and National Landscapes are high value landscapes and we welcome the call to prioritise these special places for action. Designated Landscapes cover 25% of Wales and are home to sources of water for the biggest centres of population and benefit nature, climate and recreation. Underinvestment is sewage treatment is a significant issue in rural areas. Meanwhile, in many cases Designated Landscapes are impacted by activity in the wider river catchments upstream and outside of their boundary. However, it is important to recognise the work that is being done by Designated Landscape teams to engage and work with stakeholders and partners in those wider catchments, often with limited resources and jurisdiction. For example, the majority of the Cleddau River catchment falls outside the Pembrokeshire Coast National Park boundary. The National Park Authority as part of Tirweddau Cymru is working to improve the condition of the Cleddau through a range of actions, including through the Nutrient Management Board and engaging and supporting landowners and land managers as well as through education and awareness raising in schools and local communities.” – Andrew Blake, Chair Tirweddau Cymru
“The ‘Rivers at Risk’ report casts a cloud over the reputation of England’s most important protected wetland, the Broads. How can the home of a quarter of our threatened species, living in and amongst 200km of lakes and rivers, be dirtier than waterways in any of the other National Parks?
The Broads draw millions of visitors for walking, cycling, boating and birdwatching. They pay their dues and, along with the local economy that welcomes them, have every right to expect cleaner rivers. The Bure, with its headwaters in endangered chalk streams, is the Broads’ longest river, and, together with its tributaries, must get the attention it needs.
Duties enshrined in the Levelling-Up and Regeneration Act 2023, require national and local government, water companies and regulators to protect the Broads and promote their enjoyment by the public. It’s a disgrace that these obligations are being flaunted and ignored.
The Broads wetlands are recognised globally under the Ramsar Convention, but ‘Rivers at Risk’ shows that the UK falls well short of its legal obligations to use them wisely and maintain their ecological character through effective management and monitoring.” – Dr Mark Collins, Chair of the Broads Society
Our new research shows National Park rivers are being failed by government and water regulators and are now under threat.
The Cunliffe Independent Water Commission has published recommendations for reforming the water regulatory system, but throughout this detailed report National Parks fail to be mentioned.
The UK Government has released official data on the state of nature in England’s Protected Landscapes, marking a big step forward in understanding how these special places are faring.
