Warning of Blue Green Algae in Lake Windermere

19 October 2011

The Environment Agency who regularly inspects lakes and rivers and carries out water sampling has informed South Lakeland District Council that there is evidence of blue green algae. 

The following waters have recently been found to have a blue-green algal bloom or the potential for one to form and should be treated with caution.

• Miller Ground, Lake Windermere
• Steamboat Museum Pier, Lake Windermere
  . 

Anyone using lakes, rivers and reservoirs should treat all blue green algae blooms with caution and contact should be avoided as skin rashes and illness may occur if the water is swallowed

Farmers and pet owners should also prevent livestock and animals coming into contact or drinking the affected water, as it can sometimes prove fatal for animals.

SLDC’s Public Health and Licensing Manager, Tracy Howard, said: “Blue green algae can potentially make people feel quite ill if swallowed or even by just swimming in it.  We just want people to be aware of the affects and are asking people to be extra careful and vigilant when using the lakes and rivers for recreational purposes during the summer months.  The public should observe any notices near affected areas and avoid contact or drinking the water.”

Many waters are vulnerable to problems with blue green algae, typically between June and November.  All blue green algae blooms should be assumed to be toxic and the blooms vary in colour from discoloured green, blue-green, greenish brown, or reddish brown.
