Explore water quality across the Yarra

EPA forecasts water quality for 4 sites along the Yarra River in partnership with Melbourne Water.

EPA also issues alerts when there is an issue affecting a waterbody in Victoria.

Yarra Watch season is now closed. Always check for signs of pollution before you swim.

 

Avoid swimming near stormwater or river outlets 24-48 hours after heavy rain.

Healthy swimming advice

For healthy swimming:

  • 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

Forecasts

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.

Children, older people and people with a weakened immune system are most at risk of getting sick from polluted water.

How we calculate forecasts

Melbourne Water test water samples for a bacteria found in faeces called E. coli.

E. coli is the best indicator for measuring pollution from faecal contamination in our rivers.

In poor water quality,  bacteria  may lead to illness. A common illness from swimming in poor quality water is gastroenteritis. You should see your doctor if you suspect you are unwell from swimming.

Recreational water quality standards

We assess water quality against the State Environment Protection Policy (SEPP) (Waters), which came into effect in 2018.

These standards are more stringent than standards we used previously. This ensures that Yarra Watch is more protective of health. This means swimmers can have an even higher degree of confidence in our forecasts and swim advisories.

The stricter standards will likely result in EPA advising that the water may not be safe for swimming more often. A higher number of ‘Poor’ forecasts and swim advisories does not necessarily mean that water quality is worse than in previous years.
