Why lakes matter

Lakes do far more than look beautiful. They provide drinking water, support wildlife, help power local economies and give us places to connect with nature.

But these vital ecosystems are under growing pressure. Lakes are at risk from pollution, habitat loss, invasive species and climate change.

There are over 40,000 lakes in the UK.​

Lakes are telling us something. We’re listening.

It isn’t possible to understand environmental change from a single snapshot. It takes evidence built up over time to see what’s really happening and what’s coming next.

UKCEH scientists have been monitoring lakes fortnightly for decades. When we decode our data, we can show how climate change is reshaping our lakes for nature and people.

We combine decades of data with cutting edge environmental DNA techniques, and AI and acoustic sensors, meaning our scientists can identify risks earlier and understand impacts across entire ecosystems.

Our science helps governments, businesses and communities make better decisions to protect what we love so that nature and people can thrive.

The lake attracts 7 million visitors a year.
“Lakes like Windermere are sentinels of change… More than ever, it’s vital we continue monitoring how our freshwaters are changing.”
Dr Stephen Thackery
Head of Aquatic Ecosystems, UKCEH
