Around 100 volunteers will check the water quality of Windermere this weekend as part of a citizen science project.
The Big Windermere Survey, designed by scientists at Lancaster University and the Freshwater Biological Association, returns on Sunday. People will work within the Leven catchment, which surrounds Windermere, to help build a one-day snap shot of water quality in the lake and its tributaries.
The first survey was carried out in June and the second has been funded through the Love Windermere Partnership, and is again led by Lancaster University and the Freshwater Biological Association.
Samples will be analysed independently by scientists at the university and independent laboratories to provide precise and accurate data, to help inform decision-making and action to improve water quality in the catchment.
They will be analysed for concentrations of bacteria and nutrients such as nitrogen and phosphorus, which can cause issues for both ecological and human health.
The aim of the project is to build up a comprehensive and geographically widespread picture of water quality in and around Windermere, and how it varies throughout the year.
It will be used to develop evidence-based plans to maintain and improve the lake for future generations, including by the Love Windermere Partnership.
Dr Louise Lavictoire, head of science from the Freshwater Biological Association, said: “The Freshwater Biological Association has been monitoring water quality periodically here on the shores of Windermere for more than 90 years.
“June’s survey was the largest single one-day snap shot of water quality ever undertaken in the catchment, and we’re excited to be back to continue the work with our fantastic volunteers this weekend.
“It’s really important that we build up a seasonal picture of water quality, taking into account variable factors such as rainfall, temperature and visitor numbers.
“Ultimately this will allow us to see where there are specific problems affecting the lake, and then we can collectively plan the right interventions to tackle these issues.”
