Blue Green Algae in the Lake District
When the weather's warm it's tempting to go for a dip in Windermere. But please be aware of Blue Green Algae.
Blue Green Algae naturally occurs in inland waters, estuaries and the sea. Blooms can form when their numbers become excessive, often in hot weather conditions. Once algal numbers are high, the blooms are likely to persist throughout the season, declining only on the onset of winter conditions.
We’re advised of Blue Green Algae blooms by the Environment Agency and if they are present – we’ll put notices up in those areas straight away.
During the blooming stage Blue Green Algae becomes toxic to people, but particularly to animals. Not all blue-green algae blooms and scums are toxic, but you can’t tell just by looking at them, so it’s best to assume they are.
Due to the turbidity of the water in some of the lakes here from boats and wind, the blooms can appear and disperse quickly, but are unpredictable in nature. If you notice anything that looks like a bloom, please report it to the Environment Agency incident line on 0800 80 70 60 which is open 24/7.
Take a look at the Lake District National Park's website to find out more about Blue Green Algae, the Environment Agency's blog, and refer to the government's advice on what to do if you spot it in a lake, river or the sea.
