There is currently an Amber alert toxic algae caution in place for Ruamāhanga River at Double Bridges due to moderate levels of toxic algae being observed.
We advise no swimming and for dog walkers to stay away from these sections of the river until further notice. Toxic algae represents a very real risk to human and animal health. If you have been in contact with toxic algae and are feeling unwell see your doctor or ring Healthline 0800 611 116. If you think your dog has swallowed toxic algae, take it to the nearest vet immediately.
