Swimming off at popular Surrey pond after blue green algae found

Waverley Borough Council has said people should be aware of dangerous levels of blue-green algae at Frensham Great Pond and that visitors must not go in for a swim.

Blue-green algae naturally occurs in inland waters and can produce toxins called ‘harmful algae blooms’ that can kill wild animals, farm live stock and pets.

In humans, they can cause rashes – and illnesses if swallowed.

Not all blue-green algal blooms and scums are toxic but there is no way to easily tell, according to the Environment Agency.

Frensham Great Pond is very popular in nice weather, the council said, but this can lead to overcrowding.

In the past the council has even gone as far as asking people to avoid the famous sandy beach after “huge influxes” of visitors caused numerous problems including illegal and dangerous parking, barbecues, littering, dogs fouling, and abusive behaviour towards staff members.

Posting on social media, the council which oversees and manages the pond, said: “Please be aware blue-green algae has been found at Frensham Great Pond, meaning visitors will not be able to swing in the pond at this time.

‘Stay tuned for updates as to when the algae has cleared and the pond is open again.”
