Pearson Park lake taped off after algae infestation

WARNING: The serpentine lake in Pearson Park

By Simon Bristow, Co-Editor

Visitors to Pearson Park have been urged to avoid contact with water in the lake and to stop their pets drinking from it after a potentially hazardous blue-green algae infestation.

Hull City Council said water samples have been sent for specialist testing but early assessments indicate a 95 per cent likelihood that blue-green algae is present. This naturally occurring algae, which is caused by the bacteria cyanobacteria, can pose risks to both people and animals when present in high concentrations. 

Warning signs and hazard tape and have been installed around the lake and the fountains have been switched off to minimise the risk of water spray.

The water in the serpentine lake in Hull’s oldest public park had noticeably changed to a turquoise colour over the weekend.

Councillor Rob Pritchard, portfolio holder for culture and leisure, said: “Pearson Park is a much-loved green space and we know how important it is to so many residents.  

“While these measures are precautionary, we’re acting quickly to keep everyone, including animals, safe and healthy. 

“We’re asking visitors to respect the measures in place, by not touching the water, and keeping pets on leads and away from the pond while we monitor the situation.  

“We’ll continue to keep the public updated and appreciate everyone’s understanding and support.” 

The council will continue to monitor the water and is seeking expert advice on available treatment options.
