An ambitious catchment wide project aiming to reduce flood risk to Keswick, delivering nature-based solutions to benefit nature, farming and communities.
The catchment
The catchment of the River Glenderamackin is approximately 142 square kilometres and includes the mountains and river valleys that drain into Keswick, including Mungrisdale, Troutbeck, the Naddle and St Johns in the Vale. The River Glenderamackin and St John’s Beck join to form the River Greta just upstream of Keswick.
The Glenderamackin is part of the River Derwent and Bassenthwaite Lake Special Area of Conservation (SAC). A large area of the uplands to the north of the catchment are part of the Lake District High Fells SAC. The entire catchment sits within the Lake District National Park, also a UNESCO World Heritage Site, designated for its cultural heritage.

The problem
The catchment faces multiple threats:
Increase in severe flood events due to climate change. In recent years, Keswick has been hit by devastating floods in 2005, 2009 and most recently in 2015.
Poor water quality - high phosphate levels from wastewater discharges and agricultural runoff contribute to the SAC river being in ‘unfavourable’ condition.
Poor habitat condition – important habitats such as woodlands, wetlands and ponds have disappeared from our countryside. Those that still exist are often in poor condition and are not connected, so wildlife can’t move through the landscape. Our rivers are also heavily modified including being straightened or disconnected from their floodplains creating poor conditions for fish passage, spawning and survival.
Degraded peatlands – when peat is in a poor condition it contributes to flooding and reduces habitat available for wildlife. The erosion of peat is also a source of greenhouse gas emissions.
Vulnerability to drought – drained and modified landscapes don’t hold onto water, making them susceptible to drought during the dry summer months. This has negative effects for wildlife, farms and businesses.
Changing farm payments and uncertain futures for farm businesses.
Our plan
We want to support our communities to manage flood risk. Nature often has the answers to man-made problems. Alongside existing traditional hard engineering, we are using nature-based solutions to reduce downstream flood risk by delivering a whole host of interventions including re-wiggling rivers, planting trees and restoring wetlands. We will deliver these at an ambitious scale in a multi-million-pound catchment-wide programme to make a big difference to these issues as part of an adaptive pathway, working with other agencies.
To achieve this, we’re looking at using a combination of public and private sector funding to make our vision a reality. This blended finance approach is increasingly being favoured by UK Government for nature restoration projects and through the new Environmental Land Management (ELM) Landscape Recovery scheme. This project is one of the biggest blended finance projects being worked up in England and there is significant national interest. It’s an important pilot and an opportunity to show how working together can really make a difference, not just for flooding, but to address the biodiversity crisis, whilst ensuring we continue to support and work with the local farming community.
We want to re-naturalise 4km of river, improve the condition of soils and grasslands, create 185 hectares of new woodland and 185 hectares of scrub land, restore 45 hectares of ponds and wetlands, build 5.6km of low level earth bunds, plant 6.3km bunded floodplain hedges and 7km ‘normal’ hedges and restore 30 hectares of peat.
The benefits
Reducing flood risk (by a modelled 10% off the flood peak in a 1 in 30 year event in the present day, continuing to offer protection up to 2039 (and beyond) using mid-point climate change projections)
Mitigating climate change
Reversing biodiversity loss
Improving water quality
Supporting our local farming communities
If you would like to volunteer in the area, sign-up and look for activities in the Glenderamackin Catchment.
If you farm within the Glenderamackin catchment, we have farming equipment you can borrow, detailed at the bottom of our land management page.
For more information, email Project Officer Clair.
Our progress (as of February 2024)
This project is now a DEFRA round 2 Landscape Recovery project and we will be working through the development phase.
With thanks to funding from Natural Course, we’ve been able to work with leading consultants, JBA, to model how the proposals will reduce flood risk in the catchment.
We’re continuing to work with the Rivers Trust to map ecosystem services including water availability, water quality, biodiversity uplifts and carbon sequestration and using this to inform our discussions with Buyers.
With thanks to funding from the Lake District National Parks’ Farming in Protected Landscapes funding, we are able to continue the Glenderamackin Farmer group until January 2025. This allows us to bring farmers together to help co-design the Resilient Glenderamackin project, understand grants that are available and support farmers in the catchment through the agricultural transition.
