La Nina to affect summer water quality

On the eve of summer starting, could our normal dip in the bay be at risk because of Australia’s La Nina weather alert?

Environment Protection Authority Victoria (EPA) publishes a twice-daily water quality forecast for 36 Port Phillip Bay beaches and four popular swimming spots on the Yarra River,and says the rains a La Nina system brings means we’ll need to check before we put our toes in the water for a cool off.

“La Nina weather often brings heavy rain which washes unseen pollutants off our streets, into the drains and out into the bay and river systems,” says EPA Water Scientist Paul Leahy.

“Run-off can often contain harmful microbes that can cause skin irritations, eye and ear infections, and even gastro illness especially for our kids, elderly and people with vulnerable immune systems. Anyone experiencing swim-related illness should seek advice from their doctor. .

“Every summer EPA and Life Saving Victoria (LSV) provide a daily forecast of water quality around the bay and with Melbourne Water, on the Yarra River. The forecasts are available on the EPA website, at LSV clubs around the bay in weekends and public holidays, or you can register to receive a local SMS alert.

“We want everyone to check in before they dive in and stay safe from avoidable illnesses. That goes for pets too. Dogs often get skin irritations that are harder to see under their fur. Give them a good hose down after they’ve been in for a swim.”

The forecast service rates water quality as:

Good means water quality is probably suitable for swimming.

Fair means water quality may not be suitable for swimming. Check for signs of pollution before you swim. For example; stormwater drains flowing, murky water, bad smell, and rubbish.

Poor means water quality is probably not suitable for swimming.

“If the rating is ‘Poor’ don’t go in. But conditions can change quickly, so be prepared and take a good look at the water before going in.

• Avoid swimming near stormwater drains

• Avoid swimming for 48 hours after rain

• Try not to swallow water during recreation

• Cover cuts and scratches with waterproof bandages

• Wash your skin with soap after touching the water and shower after swimming

“Our water quality is usually pretty good, but Beach Report and Yarra Watch will alert you if that’s not the case.,” said Paul

The Beach Report and Yarra Watch service operates between 1 December and Labor Day (14 March 2022).
