Big Windermere Survey secures funding from Lake District Foundation and National Trust

Written By Jo Gamble

13 July, 2023

The Freshwater Biological Association is delighted to announce that it has just secured funding from the Lake District Foundation and National Trust to continue with the Big Windermere Survey.

The Big Windermere Survey is a citizen science project run by the Freshwater Biological Association and Lancaster University that aims to provide evidence and understanding about water quality in Windermere.

The project is a huge undertaking that requires the help of an army of volunteers as well as funding to cover the costs of sampling kits, laboratory analysis and staff time, so The Freshwater Biological Association is delighted to announce that it has just secured funding from the Lake District Foundation and National Trust to enable it to continue this innovative project with Lancaster University for another season.

Sarah Swindley, CEO at Lake District Foundation, commented, “The Lake District Foundation is very pleased to be able to support the Big Windermere Survey and we are grateful to our many donors for making this possible. The Big Windermere Survey is a key part of the Love Windermere partnership, which is working together to look after this iconic lake for generations to come. Having robust data to best direct activity is vital and the survey is clearly providing this.”

Laura Ruxton, General Manager of the South Lakes Portfolio, National Trust, commented, “The National Trust values the importance of understanding Windermere’s water quality through regular sampling and testing. Through the Love Windermere partnership, we are pleased to support the Big Windermere Survey to include the community around the lake in this work.”

The next Big Windermere Survey will take place on Sunday 13th August. Volunteers are trained to collect water samples from Windermere and the rivers and lakes that flow into it, which are analysed for nutrient and bacterial concentrations at independent laboratories, producing the largest, one-day snapshot of conditions in Windermere.

To date, The Big Windermere Survey has included four surveys – summer and autumn 2022, and winter and spring 2023 – representing a year of data spanning the four seasons.

Dr Lynsey Harper, Senior Scientist at the Freshwater Biological Association, explains, “It is important to gather data in each season throughout the year to identify patterns in the concentrations of nutrients, such as phosphorus and nitrogen, and bacteria that can indicate the presence of faecal matter. This allows us to determine which locations are of good or poor water quality year-round and which locations experience poor water quality in certain seasons. For example, higher visitor numbers in spring and summer may increase nutrient inputs from households to the wastewater system and eventually the lake. In autumn and winter, higher rainfall and runoff from the land surrounding the lake can also increase nutrient inputs to the lake.”

Dr Ben Surridge, Senior Lecturer at Lancaster University, adds, “In combination with warm, dry and stable weather conditions, high nutrient concentrations can increase the frequency and intensity of algal blooms, which can be harmful if the bloom produces toxins or lowers dissolved oxygen levels in the lake water. The Big Windermere Survey informs targeted action on the ground, as the data from the survey are used to inform decision-making processes and to bring about action to maintain and improve water quality.”

If you’d like to see the results gathered from the four rounds of the Big Windermere Survey so far, these are publicly available on the Freshwater Biological Association website.

If you would like to get involved with the Big Windermere Survey on Sunday 13th August and become a scientist for the day, get in touch at windermere@fba.org.uk

Emma Kelly, Windermere Project Officer, says, “Getting involved in the Big Windermere Survey as a volunteer is a great way to get out and about on a Sunday morning, helping to collect valuable data to assess the water quality of the Windermere catchment. Absolutely anyone can get involved – you can even bring along family and friends, including four-legged friends!”

Pond Restoration Training: North West England - 6th & 7th July 2026
from £250.00

NEW COURSE: Pond Restoration Training: North West England on 6 & 7 July 2026. From £250.00

Ponds are increasingly recognised as critical features for biodiversity conservation across UK landscapes. This two-day course will introduce participants to the science and best practice of pond restoration.

Helen Greaves of the Pond Restoration Research Group at University College London (UCL) is a co-founder of the Norfolk Ponds Project (NPP) and Executive Director of the NPP Community Interest Company (CIC). With over 15 years’ experience restoring ponds and researching their ecological recovery, and following publication of the recent Guide to the Restoration, Creation and Management of Ponds, Helen is keen to share key lessons and practical insights from both the UCL and NPP teams.

The course will include a combination of lectures, workshops, and field visits focused on the restoration of degraded overgrown ponds and in-filled “ghost ponds”.

Participants will be introduced to the scientific evidence underpinning pond restoration, including the benefits for freshwater and terrestrial biodiversity. The course will also cover the key DOs and DON’Ts of restoration, including pond selection and important considerations during the restoration process.

Field visits will explore two contrasting pond landscapes typical of West Lancashire. One site is situated within a lowland floodplain landscape, while the other lies within a higher arable setting adjacent to a nature reserve. These visits will provide an opportunity to compare ponds across different land uses, including farmland and conservation-focused landscapes. Participants will consider how landscape context influences restoration potential, management approaches, and ecological outcomes, including the specific challenges and opportunities associated with restoring existing ponds and resurrecting ghost ponds.

The course will also address approaches to engaging landowners, farmers, and local communities in pond conservation, alongside practical routes for securing funding to support restoration work.

Participants on all FBA courses must be 18 years and above.

Location: West Lancashire (near Ormskirk)

River Restoration Modelling course: upland river settings - Date TBC
River Restoration Modelling course: upland river settings - Date TBC
from £234.00

This River Restoration Modelling Course covers the upland river settings. The lowland river settings course may be booked separately.

With the advent of improved computing power, user-friendly software and easier acquisition of base data, the tasks required to deliver river naturalisation have become easier. In particular, the ability to rapidly simulate the action of water across the riverine landscape has revolutionised our ability to understand fluvial processes and to harness this knowledge to rejuvenate degraded systems in a targeted manner.

This course introduces simple 2D modelling through a set of hands-on exercises to develop flow simulations across a varied fluvial landscape. It is targeted at those interested in this area but with no prior knowledge of river modelling. Anyone interested in NFM, river and floodplain restoration and tributary and drainage improvement will benefit from the course. Delegates will, under supervision, build their own models (no laptop required) and assess outputs using the results to suggest local interventions that improve hydromorphological functioning. All software and base data are free and these, together with the results from the day, can be downloaded and retained by delegates at the end of the course.

Key course components:

  • The history and value of modelling

  • Different types of models and their uses (catchment, NFM, river design, ecohydraulics etc.)

  • Mapping flow in the catchment using GIS & rainfall models

  • Simple reach-scale modelling to map opportunities and constraints

  • Example modelling exercise

  • Utilising the results for system naturalisation

Date: To be confirmed soon

Note: This is a one day course and will explore an upland river setting. Lunch will be provided.

Location: Field Studies Council Laboratory, Castlehead, Grange-Over-Sands, Cumbria, LA11 6QT

Tutor: George Heritage & Kieran Sheehan

Price: £260 for non-members and £234 for FBA members

Freshwater Biology and Ecology Handbook (digital copy with £5 donation)
Freshwater Biology and Ecology Handbook (digital copy with £5 donation)
£5.00

This handbook provides an overview of the biological and ecological methods used to assess the status of the freshwater environment, with a focus on invertebrate methods. Good river health is the key outcome and aim of this work. The handbook describes how biological methods are used in the UK to improve and protect freshwater quality by delivering the Water Framework Directive. The principles underlying that delivery are constants and feed forward into possible reshaped UK approaches in the future.

The book is aimed at students, operational ecologists (including citizen scientists), nascent environment protection agencies (including those joining the European Union), and policy makers in the UK.

· Chapter 1 provides an overview, including the legal framework for freshwater biological monitoring

· Chapter 2 is a practitioner’s guide to the standard methods for invertebrate sampling and data collection

· Chapter 3 provides an understanding of current river invertebrate classification methodologies, focussing on RIVPACS and surveillance & operational monitoring.

· Chapter 4 looks at other sampling methods for investigative monitoring

· Chapter 5 looks at indices and data analyses for investigations, including the increasing contribution from citizen science programmes.

· Chapter 6 considers the reporting methods used in the UK and the EU, specifically with links to investment programmes, driven by the monitoring and assessment information. It also provides links to publicly available datasets.

The focus is on river invertebrate methodologies and on status classification, using the UK’s RIVPACS approach to provide a working example of what is needed to set up a biological monitoring programme for a national initiative, a river catchment or a specific tributary. Public participation through citizen science initiatives and are increasingly important for gathering data and presenting evidence, and those methods are also described. Most invertebrate methods use similar key principles, and we expect users to modify and adapt methods to their specific situations as needed.

Several important biological and ecological methods are not covered in this handbook, including fish, macrophyte, diatom, DNA, and river habitat assessments, river restoration methodologies, still-water methods, and statistic and computing methods. We would like other specialists to work in collaboration with FWR and FBA to add additional chapters or sections to expand its coverage.

The core elements described here are the basis for training programmes and university teaching, to provide the expertise to consolidate the improvement of river health into the future. We also hope that they provide a useful insight for civil servants, water managers, specialists, and river conservation groups working to improve and protect our invaluable freshwater environment.

In making this publication free of charge and for public good, we hope to accelerate the development and use of biological monitoring and assessments to improve the understanding of freshwater systems around the world.
