The Big Windermere Survey Results

The Big Windermere Survey has completed nine rounds of surveys representing two full year’s worth of data spanning the four seasons for 2022/23 and 2023/24.

Launched jointly by the Freshwater Biological Association (FBA) and Lancaster University, the Big Windermere Survey has recruited a team of local volunteer citizen scientists to help assess the environmental health of Windermere.

Citizen scientists are trained to collect water samples from approximately 100 different locations on Windermere and in the rivers and lakes that flow into it. The samples are analysed for nutrient and bacterial concentrations at independent laboratories, producing the largest, one-day snapshot of conditions in Windermere.
