Toxic algae poses risks in two Ka¯piti Coast river sites

Our Greater Wellington marine and freshwater team says that toxic algae has increased to amber levels at the sites, meaning we strongly advise caution to swimmers. . .

And just like that, it’s February already. And on the back of the warm weather and minimal rain I want to highlight the risks of toxic algae in our local rivers.

Swimmers are being advised to take caution while dog owners should keep dogs on leashes or avoid the two river sites along the Kapiti Coast with toxic algae, including detached algal mats being identified.

The sites are located at Otaki ¯ River at State Highway One and Waikanae River at Jim Cooke Park.

Our Greater Wellington marine and freshwater team says that toxic algae has increased to amber levels at the sites, meaning we strongly advise caution to swimmers and to check the LAWA website regularly for updates before getting in the water.

The warning bears greater significance for dog owners as dogs like the smell and taste of the algae and a small piece, only around the size of a 50c coin, is enough to kill a dog.

The risk is higher with detached algal mats being found at both sites, meaning the algae has broken off rocks in the riverbed and accumulated at the rivers edge, within easy reach for dogs.

Sites that are safe to swim in, can move to dangerous warning levels within a matter of days given the hot temperatures so it’s important to check the latest status on LAWA.

Greater Wellington is currently monitoring popular swimming spots around the region on a weekly basis to ensure the community knows when where it’s safe to swim.

Members of the public who think they or their dogs have been in contact with toxic algae should see your doctor or ring Healthline on 0800 611 116 and for their dogs, take it immediately to the nearest vet.
