Algae sighting a cue for vigilance on waterways

Despite the conclusion of Greater Wellington’s toxic algae monitoring programme, a mainstay for Greater Wellington over the summer months, officers have spotted moderate levels of toxic algae in Te Awa Kairangi/Hutt River in a stretch from Manor Park to Silverstream.

The GWRC environmental monitoring team has wrapped up the monitoring season for toxic algae and fortunately, spotted the algae while monitoring for other purposes.

This is a reminder for us on the Ka¯ piti Coast to still keep a watchful eye on our waterways, especially the Waikanae and O¯ taki rivers.

The late bloom is likely attributable to the run of warmer weather, which despite the change in season, has continued.

While rain and cooler weather is obviously more common through autumn and winter and helps flush out and prevent further algae, it’s important to remember the risks of toxic algae developing in our waterways.

If you’re still enjoying the water or taking dogs to the river, it’s important to remember the risk, as dogs love the smell and taste of toxic algae, with an amount as small as a 50¢ piece, enough to kill one.

It highlights the value in knowing what to look out for and what to do if you or your pet come into contact with it. Especially, now that monitoring has finished and the LAWA website is no longer being updated with changes in alert levels or confirmed sightings.

If anyone thinks they or their dog has been in contact with toxic algae, they should see their doctor or ring Healthline on 0800 611 116 and, for their dog, take it immediately to the nearest vet.
