The presence of the potentially toxic algae Phormidium has been confirmed in the Cardrona River, prompting a warning from the Otago Regional Council for people (and dogs) to avoid contact with waters in the river.

ORC has found the naturally-occurring algae Phormidium at the Regional Council’s Mt Barker sampling site on the river.

Signs have been put up at popular locations on the river to warn the public of the risks associated with the algae.
