Signs of toxic blue-green algae have been spotted at Roath Park Lake. Natural Resources Wales (NRW) has alerted Cardiff Council that blue-green algae may have reappeared at the popular beauty spot.
This week, samples of the algae have been taken by the NRW to confirm if it is toxic. Signs have been put up to warn the public and, following the warm weather, people are advised not to swim or make any contact with the water. It was last spotted at the popular spot back in 2018.
It is harmful to dogs and other animals if they enter the water. In some cases, it can kill a dog between 15 minutes to an hour after drinking the contaminated water.
