Catchment partnership vision
Our vision for West Cumbria is for healthy rivers, lakes and estuaries that support wildlife, are used sustainably to benefit people, and are valued by all. We will work collaboratively to plan, fund and deliver actions to:
- reverse redundant physical modifications and allow natural function
- improve water quality by reducing agricultural diffuse pollution and wastewater inputs
- increase resilience to climate change
- reduce the impacts of floods, droughts and coastal erosion using sustainable methods
- provide high quality, diverse and connected habitats that support a wide range of wildlife, and control invasive species
- support farm businesses to adopt sustainable practices that provide diverse habitats, clean water and ‘slow the flow’ measures
- increase opportunities for local communities to enjoy, understand and safeguard their catchments
- develop a robust evidence base to underpin action.

Catchment challenges
Current challenges identified by partnership
Physical modifications
Straightened and perched rivers and obstacles to fish passage, particularly Yearl weir
Pollution from abandoned mines
Abandoned metal mines in Newlands Valley and Threlkeld causing zinc and cadmium pollution
Pollution from agriculture and rural areas
High sediment and phosphate in lower Ellen and Derwent tributaries and coastal streams, and low dissolved oxygen in lakes
Wider water environment challenges identified by partnership
Nature Recovery, designated areas for nature and biodiversity
Biosecurity risks from recreational use of pristine lakes, high likelihood of spread of invasive species from other lakes
Build environmental resilience and adaptation to climate change
Flooding, drought and high water temperatures threaten communities and native wildlife, particularly salmonids
Support Nature Recovery Network and Local Nature Recovery Strategy
Multiple strategies exist including the Catchment Partnership plan, LNRS and Lake District National Park Plan and need to be joined up
Reduce storm overflows and drainage system incidents
Ageing combined sewer infrastructure systems with frequent overspills throughout the catchment
Improved bathing waters (including inland)
Well-used lakes, including Derwentwater and Bassenthwaite Lake, are not designated as inland bathing waters
Protect and restore healthy soils and nutrient balance
Better soil management could increase infiltration and organic matter, helping reduced flood risk, improve water quality and sequester carbon
Future challenges predicted by partnership
Changes to the natural flow and water levels
Modified channels throughout the catchment are susceptible to drought and spate events
Invasive Non-native Species
New Zealand pigmyweed is present and has potential to spread to pristine lakes, increasing tourism and recreational use of lakes causing greater biosecurity risks
Pollution from waste water
Growing populations and tourism combined with more low flow events and storm events (combined sewer overflows)
Future challenges predicted by Environment Agency
Future challenges in 2050
- Invasive Non-native Species
- Physical Modifications
- Pollution from Agriculture and Rural Areas
Emerging challenges
- Pollution from Agriculture and Rural Areas
- Pollution from waste water
- Physical Modifications
Partnership success highlights 2016 to 2021
Since 2016 numerous projects have enhanced the catchment and in-stream habitat by improving water quality, restoring biodiversity and reducing flood risk:
- United Utilities' Thirlmere Resilience Project is employing sustainable land management upstream of Thirlmere Reservoir
- The Derwent River Corridors Group completed 51 habitat improvement projects, informed by annual fish population surveys at 150 sites
- The River Restoration Strategy partnership completed 15 innovative projects to restore natural processes
- Cumbria Wildlife Trust restored extensive peat areas on White Oak Moss and Matterdale Common
- Large upland woodlands were created by National Trust and the Woodland Trust
- The National Trust's Riverlands Project began by restoring natural function in Brockle Beck
- West Cumbria River Trust's Cocker and Glenderamackin natural flood management projects reduced runoff and created pond and wetland habitats.Further work targeted water quality issues: Natural England's Catchment Sensitive Farming delivered advice and interventions to reduce agricultural runoff and Facilitated Farmer groups in the Cocker, Crookhurst, Glenderamackin and Borrowdale shared best practice. The 'Ellenwise' project in the Crookhurst catchment reduced agricultural pollution to improve the condition of Allonby bathing waters. United Utilities upgraded multiple wastewater treatment works and the 'Water and Abandoned Metal Mines' Programme began delivery of the Gategill minewater remediation scheme.

Partnership development plans
The West Cumbria Catchment Partnership will continue delivering multi-benefit projects, integrating flood risk reduction with environmental improvements including coastal and marine projects. The partnership would benefit from greater involvement of local communities and specific interest groups in project development. The partnership aims to utilise a broader range of funding sources including private investment in delivering landscape scale habitat improvement and make use of opportunities afforded by Biodiversity Net Gain and Nutrient Neutrality legislation.
