The Community and Public Health division of the Canterbury District Health Board has lifted its algal bloom health warning issued at Pegasus Lake on 14 February 2017.
Recent water testing at Pegasus has shown the quantity of potentially toxic blue-green algae (planktonic cyanobacteria) in the lake has decreased and concentrations are now below levels of concern to public health.
Dr Ramon Pink, Canterbury Medical Officer of Health, says as we move into winter there is a decreased chance of the toxic algae returning until the warmer months.
"People are reminded to be aware of the signs of the presence of cyanobacteria in the lake, as the monitoring frequency has now reduced from weekly to monthly," Dr Pink says.
