Stay safe at the river or beach this summer! The warm weather is here, and it’s the perfect time to cool off in our rivers and at the beach. But before you dive in, there are a few things to keep in mind to ensure you and your whānau stay safe in the water this summer.
Watch out for hidden hazards! Floods earlier this year may have shifted debris in rivers, especially in the Motueka Valley. A lot of large objects such as trees, nets and truck wheels have already been found, so check underwater before diving in – things may not be as clear as last summer.
Our environmental officers test popular swim spots weekly for E.coli, enterococci, and toxic algae. Water quality is currently looking good, and post-flood data shows the Motueka River is back to normal.
We monitor water quality at the District’s hot spots throughout the season, from Collingwood and Tata Beach through to Kaiterieri, Māpua and Moturoa/Rabbit Island, and even the Tākaka, Motueka, Lee and Aniseed rivers.
Check the latest water quality and toxic algae results at tasman.govt.nz/swimming-water and tasman.govt.nz/toxic-algae-monitoring-results.
We are certainly spoilt for choice when it comes to swimming in our rivers lakes or beaches.
But as we head into the summer holidays, it’s worth mentioning the potential for the water quality at your favourite spot to change with the weather and/or environmental factors.
Rain is the most common reason for these changes and if we happen to get a downpour, our recommendation is to avoid entering the water for at least 36 hours, but preferably 48.
There is still a risk to swimmers, even when the sun comes out soon after the rain has abated.
We are well into our routine testing of water quality and in most cases, the results are largely excellent for most spots – Moturoa/Rabbit Island, for example, remains a perennial winner for safe swimming.
Some sites are more vulnerable to high faecal indicator bacteria than others and we have had several instances of concern in the last three weeks - there are no new locations of concern and nearly all of them have been due to rain.
Enjoy the water – safely!
