- Toxic algae identified in Waihopai River, posing risks to people and animals.
- Residents urged to avoid algae and monitor other regional waterways for contamination.
- Waiau River alert remains active near Excelsior Creek despite removal in Kennington.
Toxic algae have been detected in the Waihopai River upstream of Queen’s Drive, according to recent monitoring by Environment Southland. While algae are naturally present in waterways and often harmless, certain species can produce toxins and grow rapidly under stable river flows and warm conditions.
Environment Southland has issued a reminder for residents to be vigilant. Toxic algae are typically identified as dark green or brown slime on rocks or dark brown to black mats along the water’s edge. Exposure to or ingestion of these algae can cause serious health risks for people and animals.
Residents are urged to avoid direct contact with affected areas. Dogs should remain on leads, and children should be kept away from contaminated water. If you or your animals experience health symptoms after contact, seek medical or veterinary attention immediately.
Although the toxic algae alert has been lifted for the Waihopai River at Kennington, the Waiau River near the Excelsior Creek inflow remains under alert. Environment Southland advises that similar algae growth could be occurring in other waterways across the region due to the current conditions.
“We encourage river users to take the time to familiarise themselves with how toxic algae look and stay updated through our website,” said a spokesperson for Environment Southland.
