Mats of Toxic Algae on rocks in the Hutt River

Toxic Algae in the Hutt River

Hot weather and low rainfall have combined to increase the risk of toxic algae with parts of the Hutt River now over the limit for safe swimming.

People are strongly advised not to swim in the Hutt River between Moonshine Bridge and Fairway Drive Bridge, or in the Pakuratahi River from SH2 to where it joins the Hutt River in Kaitoke Regional Park.

Children should be kept away from water in these sites and dogs should be kept on a lead.

“No detached mats of toxic algae have yet been seen at any of our monitored sites. However this could change rapidly especially during warm weather, so we are urging people to be careful near all waterways throughout the region,” says Dr Mark Heath, Senior Environmental Scientist at Greater Wellington.

Given the rapid growth of toxic algae, and its potential change in coverage between weekly monitoring points, people are also urged to know what it looks like. They should check out information signs around popular swimming holes and visit Greater Wellington’s Is it Safe to Swim? website and Facebook page for images and more information about toxic algae.
