Windermere to get 40 signs warning of algae poisoning risk

Dozens of signs warning people about the dangers of algae poisoning are to be placed around England’s largest lake.

About 40 notice boards alerting visitors to blue-green algae blooms, which can produce toxins that make humans ill and be fatal to pets, will be installed at Windermere, in the Lake District.

Blooms occur naturally but are more frequent during warm, dry weather and are exacerbated by nutrients from phosphate in pollutants such as sewage.

Funded by the Environment Agency (EA), a further 40 signs will be placed at other locations across Cumbria.

The Love Windermere Partnership, which includes organisations such as the EA, Lake District National Park Authority and United Utilities, said it was installing the permanent signs in response to requests for “clearer and more consistent public information”.

As well as explaining what blue-green algae looks like, the notices will provide guidance on where to find current information about blooms and how to report suspected sightings using the Bloomin’ Algae app, external.

The microscopic organisms can look like blue-green paint, scum or greenish-brown discolouration.
