Three dogs have died after drinking water from a Dartford fishing lake containing poisonous Blue-green algae. 

It has been confirmed that the trio of canines drunk and swam in Brooklands Lake on May 17.  

Seven other dogs, who were part of the pack out with a dog walker, are still receiving veterinary care at Parkvets Vet Hospital in Sidcup. 

The Environment Agency (EA) has confirmed that initial tests have detected the lethal Blue-green algae in the lake off off Powder Mill Lane.

Further samples are being tested.

Police have cordoned off the area and warned dog walkers to avoid the lake.

The lake will remain closed until the results of the further analysis have been received.

Veterinary surgeon Emily Brady, at Parkvets, said: “At this time of the year, and throughout the summer and autumn, blue green algae can produce a potential toxin that can be found in lakes and ponds. 

“The algae can bloom suddenly as a result of certain conditions such as increased levels of sunshine, or fertiliser run off from fields.

"This means that water that was previously safe can suddenly become toxic.

“If this toxic water is ingested by dogs drinking from or swimming in the lake, they can suffer serious health complications and in many cases - such as those we have unfortunately seen today - it can quickly be fatal. 

“There are also serious health risks to humans who come into contact with infected water.”

The lake will be closed for at least a week, authorities have confirmed

Initial symptoms of algae poisoning include muscle tremors, an increased breathing rate, vomiting, diarrhoea, collapses and seizures – and can progress to death in as little as 15 minutes.

The Environment Agency has confirmed that there is no action that the council can take to remove Blue-green algae from its lakes or prevent it growing.

The lake is leased by the council to the Dartford and District Angling and Preservation Society (DDAPS).
