LIFE Dee River is a £6.8m project to transform the River Dee and its catchment by restoring the river and its surroundings back to their natural state. This will bring many benefits to the environment, most notably improving the numbers of salmon, lamprey and freshwater pearl mussels to help them become more sustainable in future.
The Dee is the largest river in North Wales with a catchment area of more than 1,800 km2. It is one of the most highly regulated rivers in Europe, and along with Llyn Tegid it has been designated as a Special Area of Conservation (SAC).
From its headwaters in the uplands of Snowdonia, the Dee descends via Llyn Tegid, the largest natural lake in Wales. After flowing through a broad valley to Corwen, it tumbles eastwards through the spectacular Vale of Llangollen, under the famous Pontcysyllte Aqueduct World Heritage Site, before breaching the Welsh foothills near Bangor-on-Dee, and meandering northwards through the Cheshire plain to its tidal limit just below Chester.
The main uses of the River Dee are farming, predominantly cattle and sheep grazing; water abstraction for water supply for 2.5m people; tourism including recreational angling, canoeing and navigation; and nature conservation.
Action we’re taking
removing the constraints to fish migration and wider ecological connectivity
restoring or improving natural riverine physical processes, features and habitats in at least 55 km of river
improving agricultural and forestry land management practices to reduce the input of nutrients and sediment entering the SAC
initiating conservation management for the critically-endangered freshwater pearl mussel
establishing and building long-term positive relationships with key stakeholders during and beyond the life of the project
We will fully or partially remove five weirs in the Dee and tributaries and install fish passage solutions in a further six weirs. This will increase access for fish and improve hydromorphology in 33km of river, benefiting all habitats and species.
We will carry out over 6km of habitat improvement in the river including the addition of more than 4,000 tonnes of gravel, 4,500 tonnes of boulders, and 1,000 tonnes of woody material.
At least 35km of land along the river bank will be restored through managed grazing, fencing and planting, and 2km of bank protection and historic artificial embankments will be removed or breached.
We will improve forestry infrastructure by installing two river crossings and blocking 21 forest drain culverts which will reduce pollution risk in 600ha of forestry in the SAC catchment.
By working closely with farmers, we will help improve agricultural practices to reduce the input of nutrients, chemicals and sediment entering the SAC.
Conservation management for the critically endangered freshwater Pearl Mussel
Using Dee pearl mussel stock, we will captive rear and release juvenile mussels in suitable habitat, thereby increasing the population of the river tenfold. We will continue this programme after the project is complete until the population is re-established.
Engaging with our local community
The communities living along the River Dee and Llyn Tegid will be at the heart of the project. We will work closely with local people to ensure they understand the biological, social and economic value of the habitats and species, the river and the SAC in terms of their historic and present-day importance. Our hope is that they will feel a greater sense of community ownership and responsibility for the Dee and ensure the project’s legacy continues for years to come. We will be encouraging people to get involved as much as possible by holding over 50 events during the project’s lifetime including river walks and talks, workshops, open days and a one-day river festival.
Outcomes of the project
restoration of natural riverine processes and morphology
habitats and species moved towards favourable conservation status
reduction in pollution of the river with biodiversity and drinking water benefits
improved Salmon and other fish populations
