Tasmanian Irrigation advises that Craigbourne Dam in Tasmania's South East will remain closed to the public due to the presence of a blue-green algal bloom.

The dam is closed to all recreational activities, including fishing as the naturally occurring algae remains at elevated levels.

TI Chief Executive Chris Oldfield said that members of the public should adhere to these warnings.

"TI understands that closing the dam may inconvenience some members of the public but this is necessary to protect the community," he said.

"TI advises against the consumption of any fish caught from the dam as the current levels within the dam may present a risk to human health, including skin irritations and gastro-intestinal illness."

TI is continuing to monitor the algal bloom and will re-open the site once results show a return to safe levels.
