There is currently a red alert toxic algae warning in place at Hutt River at Silverstream due to high levels of toxic algae being observed. The presence of detached mats has also been observed. This makes it easily accessible and represents the highest risk to young children and dogs.
We recommend no swimming and keeping dogs away from this part 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 ring Healthline 0800 611 116. If you think your dog has swallowed toxic algae, take it to the nearest vet IMMEDIATELY.
