Dee
The Dee Water Framework Directive (WFD) Management Catchment is a landscape of real contrasts, stretching across the border of England and Wales and linking the mountains of Eryri (Snowdonia) to the open plains of Cheshire and the wild mudflats of the Dee Estuary. There are thriving communities such as Chester, Wrexham and Whitchurch, as well as a vast range of farmland, woodlands, canals and wildlife‑rich waterways.
For our Environmental Destination (ED) programme, we are focusing on a specific “area of interest” within the catchment, relevant to our abstractions. Our focus is those surface water bodies where we actively abstract water or where our groundwater abstraction impacts on flow to surface waterbodies. These four water bodies are Morlas Brook, Shell Brook, Worthenbury Brook (Worthenbury Lower) and Aldford Brook—and they represent the full character of the Dee system, from fast‑flowing upland rivers to peaceful lowland streams weaving through agricultural landscapes. Some influencing abstractions sit just outside the Dee catchment, so we’ll also be working closely with neighbouring catchments to make sure our efforts are joined‑up – specifically the Severn Middle Shropshire and the Weaver Gowy management catchments.
This is an area rich in special habitats, including Sites of Special Scientific Interest (SSSIs) such as Shell Brook Pastures and the Afon Dyfrdwy (River Dee) itself. Local authorities manage many of the smaller watercourses, and the much‑loved Llangollen Canal adds heritage and recreational value. All of this work is supported by the Middle Dee Catchment Partnership—a collaboration of farmers, communities, environmental groups and local organisations who share a common goal: a cleaner, healthier, wildlife‑rich water environment. Through shared evidence, coordinated action and community involvement, the partnership is working to enhance biodiversity, support sustainable land management and ensure the Dee catchment continues to thrive for both people and nature.
We need your help!
Your involvement is crucial as we work together to better understand the Dee. We will be conducting a workshop on 1 July 2026 at Whixall Social Centre, Shropshire, SY13 2NA. We hope you can attend and bring your local knowledge, practical experience, and on‑the‑ground perspective that we simply can’t capture through data alone. Together we hope we can build an accurate picture of the catchment, help identify viable water resource options, highlight potential opportunities to improve in-river ecology and shape partnership projects that genuinely reflect local priorities. Your input ensures that the plans we develop are realistic, collaborative, and capable of delivering real improvements for the water environment. Ultimately, by working closely with us now, you’ll be helping to secure healthier rivers, more resilient catchments, and better outcomes for the communities and sectors that depend on them.

What are our objectives and investigations?
Understand what river flow targets and changes to water abstraction may be needed to support a healthy water environment in the Dee.
Check how well the Environment Agency’s national modelling reflects local conditions. You can view their modelling in the Modelled Abstraction Reductions – National Framework for Water Resources 2025.
Compare the national modelling with improved local data to make sure we’re getting an accurate picture of the catchment and its needs.
Explore options to improve and protect river flows, including reducing our own abstractions where necessary. We’ll also look for opportunities to work with local partners and develop Nature‑Based Solutions (NBS) that strengthen the catchment’s resilience.
Use the evidence gathered to build confidence in any future abstraction changes, helping us prioritise actions and plan a realistic timeline for making improvements.
Feed into the development of our Water Resources Management Plan (WRMP), which outlines how we will meet long‑term challenges such as population growth, drought, environmental pressures and climate change, while ensuring a reliable water supply. The plan is being developed alongside the Water Resources West Regional Plan, which sets out how all abstractors in the region will work together to secure water supplies over the next 60 years. The first plan was published in June 2025 and is available here: Water Resources West Final Regional Plan — Water Resources West.
So who abstracts water and how much?
Severn Trent operates two public water supply groundwater abstractions in the catchment with a licenced abstraction of 9Ml/d.
Other sectors with abstraction licences in the Dee Management Catchment: - The data below is from the EAs Waterhub site: North West | Environmental Destination - Get involved! | Engage Environment Agency. This site shows that there is 741Ml/d of fully licenced consumptive abstraction in the Dee catchment (England only), with the following proportions allocated to different sectors. These abstractions are from both surface water and groundwater.
What have we done so far and what have we got planned for this investigation?
We are working to a deadline of 31 December 2026 to deliver the first phase of Environmental Destination investigations. By this date we will have developed abstraction reduction scenarios, compiled a high-level list of potential options which enable the proposed reductions or support the ecological needs of the catchment and we will deliver a narrative of how we have come to our decisions.
During 2025:
WRW water companies have been working together and with regulators to agree the scope and methods for these investigations.
We have been analysing data and previous investigations to develop an understanding of the catchments and understand current flow pressures and impacts on ecology.
During 2026:
We will be holding engagement sessions to talk to other abstractors, water users and stakeholders to develop our understanding of the catchment and pressures on water. We will be looking for opportunities to get involved in existing projects and work with you to develop new opportunities to improve water resources and low flow conditions in the catchment. Once confirmed the sessions will be listed here along with a booking form. In the meantime, you can register your interest by providing your contact details below.
We will be undertaking modelling work to enhance the understanding of the catchment, look forwards at the potential impacts under one or more climate change scenarios. Along with information collated from stakeholders we will assess the EAs national framework reduction numbers to identify what reductions may be needed in the future to public water supply abstractions.
We will begin to prioritise the actions that are needed and develop an approach through the WRMP and regional plan to address these.
